18www.exxelia.com Taping : dimensions Page revised 02/2 1 COMPOSITION NPO capacitors are produced by using a dielectric made of titanium dioxide (Ti O 2 ) modiﬁed by magnesium oxide Mg O (white ceramics) or a rare earth oxide, e.g. Nd 2 O 3 (other NPO ceramics). As a consequence, these ceramics are non ferro-electric materials with a low dielectric constant ( εr ≤ 110). Other additives are used to dope the dielectric constant up to 300. Though der- ogating from CG class, doped dielectric constant features a linear temperature drift and a matchless stability compared with class 2 ceramics. The wide range of possible NPO dielectric compositions enables to use the ma- terial best suited to the application :

standard applications,
high voltage,
high temperature,
microwave,
power capacitors. «Temperature coefﬁcient» compositions are particularly suitable for imped- ance matching. These ceramics usually enable to achieve temperature coef- ﬁcients from 0 to –1 000 ppm/°C. For speciﬁc requirements, other coefﬁcients can be achieved (e.g. –3 300 ppm/°C). STABILITY As εr is low, these dielectrics are extremely stable with only minor changes under such stresses as :
temperature,
voltage,
frequency. In addition, they are not affected by piezo-electric phenomena and their dielec- tric absorption coefﬁcients are low and even non measurable for dielectrics with the lowest constants. MECHANICAL PROPERTIES Class 1 ceramics are the perfect match for metallic electrodes made of Pd or Ag-Pd alloy and have a high hardness and mechanical toughness making them resistant to thermal shocks (wave soldering for instance) and to thermal cy- cling after mounting on substrates having an expansion coefﬁcient close to the capacitor one. Ceramic chips meet CECC 32 100 and NF C 93133 standards. CLIMATIC CATEGORIES Climatic categories are identiﬁed by three-digit codes as per NF C 20700 stan- dard. Coding method is described in table 6. e.g. : – 55°C + 125°C / 56 days category is identiﬁed by code 434.

20www.exxelia.com Taping : dimensions Page revised 02/2 1 COMPOSITION Class 2 capacitors are produced by using a dielectric made of barium titanate (Ba Ti O 3 ). By nature, the dielectric is a ferroelectric compound with a high di- electric constant usually varying :

from 1 000 to 5 000 - typical of capacitors meeting 2C1 type speciﬁca- tions (BX, X7R),
from 5 000 to 15 000 - typical of capacitors meeting Z5U or Y5V type speciﬁcations. Depending on whether the dielectric contains a ﬂux additive, mainly bismuth or boron, electrodes are made of Ag-Pd alloys with high silver content or high palladium content, even pure palladium in some cases. STABILITY As the dielectric is a ferro-electric material, class 2 capacitors present signiﬁ- cant variations under such stresses as :
temperature,
voltage,
frequency. In addition, the dielectric absorption coefﬁcient can reach a few % and piezo-electric phenomena can affect the dielectric at critical frequencies (full information and speciﬁc documents available on request). MECHANICAL PROPERTIES Class 2 dielectrics are hard materials and are sensitive to thermo-mechanical stress. Stress should be limited when mounting and adequate substrates with an adapted expansion coefﬁcient used. BISMUTH OR BISMUTH FREE DIELECTRICS Class 2 capacitors are made of ceramics capable to embed a ﬂux element (e.g. bismuth or boron salt).Their eventual use will affect the choice of electrode alloys ﬁring temperature used. Capacitor behavior under such constraints as temperature, voltage, frequency and even reliability, in some applications (fur- ther information available on request), is also different. That is why French and European standard authorities have decided to differentiate bismuth from bismuth free ceramics by measuring tangent d at –55°C. Tangent Tg d (–55°C) 350.10 –4 in ﬂux free dielectrics. Flux free dielectrics are identiﬁed by sufﬁx «A» after capacitor type (e.g. CNC2A). CAPACITANCE/TEMPERATURE RELATIONSHIP Capacitance variations are deﬁned within a speciﬁed temperature range, + 20°C being the reference temperature. This characteristic is expressed by as- sociating the temperature range and capacitance stability.

A simpliﬁ ed schematic for the equivalent circuit is: Ls Rs C IR DIELECTRIC CHARACTERISTICS Insulation Resistance (IR) is the resistance measured under DC voltage across the terminals of the capacitor and consists principally of the parallel resistance shown in the equivalent circuit. As capacitance values and hence the area of dielectric increases, the IR decreases and hence the product (C x IR) is often speciﬁ ed in Ω.F or MΩ. µF. The Equivalent Series Resistance (ESR) is the sum of the resistive terms which generate heating when capacitor is used under AC voltage at a given frequency (f). Dissipation factor (DF) is the ration of the apparent power input will turn to heat in the capacitor: DF = 2π f C ESR When a capacitor works under AC voltage, heat power loss (P), expressed in Watt, is equal to: P = 2π f C Vrms 2 DF The series inductance (Ls) is due to the currents running through the elec- trodes. It can distort the operation of the capacitor at high frequency where the impedance (Z) is given as: Z = Rs + j (Ls.q - 1⁄(C.q)) with q = 2πf When frequency rises, the capacitive component of capacitors is gradually canceled up to the resonance frequency, where : Z = Rs and LsC.q 2 = 1 Above this frequency the capacitor behaves like an inductor.

The electrode ink, made from a metal powder mixed with solvents, is printed onto the ceramic sheets using a screen printing process. The sheets with electrode printed are stacked to create a multilayer structure. TERMINATIONS SINTERING PRESSING Each terminal of the capacitor is dipped in the termination ink, mix of metal powder, solvents and glass frit and the parts are ﬁ red in an oven. The parts are sintered in an oven with a precise temperature proﬁ le which is very important to the characteristics of the capacitors. Pressure is applied to the stack to fuse all the separate layers, this created a monolithic structure.

Where larger sizes are required, it is recommended to use components with ribbon or other adapted leads so as to absorb thermo-me- chanical strains. RECOMMENDED FOOTPRINT FOR SMD CAPACITORS Ceramic is by nature a material which is sensitive both thermally and mechan- ically. Stresses caused by the physical and thermal properties of the capaci- tors, substrates and solders are attenuated by the leads. Wave soldering is unsuitable for sizes larger than 2220 and for the higher ends of capacitance ranges due to possible thermal shock (capacitance values giv- en upon request). Infrared and vapor phase reﬂow, are preferred for high reliability applications as inherent thermo-mechanical strains are lower than those inherent to wave soldering. Whatever the soldering process is, it is highly recommended to apply a thermal cycle, see hereafter our recommended soldering proﬁle: Preheat zone 100 150 200 250 0 12 3 4 5 Time (min) Temperature (°C) 215°C 250°C 20°C >50°C/s Natural cool down RoHS No RoHS 0 100 150 200 250Temperature (°C) 0 12 3 4 5 Time (min) 20°C 215°C-225°C 245°C-255°C Natural cool down RoHS No RoHS 100 150 200 250 0 12 3 4 Time (min) Temperature (°C) 20°C 300 250°C 280°C Natural cool down RoHS No RoHS RECOMMENDED VAPOR PHASE REFLOW PROFILE RECOMMENDED IR REFLOW PROFIL RECOMMENDED WAVE SOLDERING PROFILE SOLDERING ADVICES FOR IRON SOLDERING Attachment with a soldering iron is discouraged due to ceramic brittleness and the process control limitations. In the event that a soldering iron must be used, the following precautions should be observed:

Use a substrate with chip footprints big enough to allow putting side by side one end of the capacitor and the iron tip without any contact between this tip and the component,
place the capacitor on this footprint,
heat the substrate until the capacitor’s temperature reaches 150°C minimum (preheating step, maximum 1°C per second),
place the hot iron tip (a ﬂat tip is preferred) on the footprint without touching the capacitor. Use a regulated iron with a 30 watts maximum power. The recommended temperature of the iron is 270 ±10°C. The tem- perature gap between the capacitor and the iron tip must not exceed 120°C,

13www.exxelia.com Page revised 02/2 1 General characteristics GENERAL INFORMATION

leave the tip on the footprint for a few seconds in order to increase locally the footprint’s temperature,
use a cored wire solder and put it down on the iron tip. In a preferred way use Sn/Pb/Ag 62/36/2 alloy,
wait until the solder ﬁ llet is formed on the capacitor’s termination,
take away iron and wire solder,
wait a few minutes so that the substrate and capacitor come back down to the preheating temperature,
solder the second termination using the same procedure as the ﬁ rst,
let the soldered component cool down slowly to avoid any thermal shock. PACKAGING TAPE AND REEL The ﬁ lms used on the reels correspond to standard IEC 60286-3.

CERTIFICATIONS Capacitors manufactured by EXXELIA comply with American and European standards and meet the requirements of many international standards. For Space qualiﬁed parts (ESA QPL), please refer to our catalog «Ceramic ca- pacitors for Space applications». QUALITY & RELIABILITY EXXELIA is committed to design and manufacture high quality and reliability products. The test cycles reproducing the most adverse operating conditions over extended periods (up to 10 000 hours) have logged to date well over 5.10 hours/°Component. Failure rate data can be provided upon request. CONFLICT MINERALS EXXELIA is committed to an approach based on «Conﬂict Minerals Compli- ance». This US SEC rule demands complete traceability and a control mecha- nism for the mineral procurement chain, encouraging importers to buy only «certiﬁed» ore. We have discontinued relations with suppliers that procure from the Demo- cratic Republic of the Congo or an adjoining country. ENVIRONMENT EXXELIA is committed to applying a robust environmental policy, from product design through to shipment. To control its environmental footprint and recon- cile this with the company’ functional imperatives, our environmental policy provides for the reduction or elimination of hazardous substances. We also focus on compliance with European Union directives and regulations, notably REACH and RoHS. RoHS COMPLIANCY SMD CAPACITORS The capacitor terminations are generally protected by a nickel barrier formed by electrolytic deposit. This barrier gives chip capacitors leaching performance far exceeding the requirements of all applicable standards. The nickel barrier guarantees a minimum resistance to soldering heat for a period of 1 minute at 260°C in a tin-lead (60/40) or tin-lead-silver (62/36/2) bath without noticeable alteration to the solderability. It also allows repeated soldering-unsoldering and the longer soldering times required by reﬂow techniques. However nickel barrier ampliﬁes thermal shock and is not recommended for chip sizes equal or greater than CNC Y (30 30) - (C 282 to C 288 - CNC 80 to CNC 94). LEADED COMPONENTS As well as for SMD products, leaded capacitors ranges can also be RoHS. These products, which are characterized by the sufﬁx «W» added to the commercial type, are naturally compatible with the soldering alloys used in RoHS mounting technology. The connections coating is generally an alloy SnAg (with a maxi- mum of 4% Ag). However, on a few products that EXXELIA will precise on re- quest, the coating is pure silver. 10 - 60 µm Metallization Silver-Palladium (or Silver) Nickel barrier Tinning: Tin-Lead No RoHs Pure Tin RoHS (W) CerUflex (polymer) 2 - 3 µm 3 - 8 µm
