APPLICATIONS
Automotive Telecommunication Industrial Medical equipment Notes
- These resistors do not feature a limited lifetime when operated within the permissible limits. However, resistance value drift increasing over operating time may result in exceeding a limit acceptable to the specific application, thereby establishing a functional lifetime. (1) The power dissipation on the resistor gener ates a temperature rise against the lo cal ambient, depending on the heatflow support of the printed-circuit board (thermal resistance). The rated dissipation applies only if the permitted film temperature is not exceeded. Furthermore, a high level of ambient temperature or of pow er dissipation may raise the temperature of the solder joint, hence special solder a lloys or board materials may be required to maintain the reliability of the assembly. (2) Specified power rating requires dedicated heat-sink pads.

Each color band appears as a single solid line, voids are permissible if at least 2/3 of the band is visible from each radial angle of view. The last color band for tolerance is approximately 50 % wider than the other bands. An interrupted yellow band between the 4th and 5th full band indicates TC25.

DESCRIPTION
Production is strictly controlled and follows an extensive set of instructions established for reproducibility. A homogeneous film of metal alloy is deposited on a high grade ceramic body (Al 2O3) and conditioned to achieve the desired temperature coefficient. Nickel plated steel termination caps are firmly pressed on the metallised rods. A special laser is used to achieve the target value by smoothly cutting a helical groove in the resistive layer without damaging the ceramics. The resistor elements are cove red by a protective coating designed for electrical, mechanical and climatic protection. The terminations receive a final pure tin on nickel plating. Four or five color code rings designate the resistance value and tolerance in accordance with IEC 60062 (3). The result of the determined production is verified by an extensive testing procedure performed on 100 % of the individual resistors. This includes pulse load screening (forR 10 ) and additional non-linearity screening (for R 30 ) for the elimination of products with a potential risk of early life failures according to EN 140401-803, 2.1.2.2. Only accepted products are laid directly into the blister tape in accordance with IEC 60286-3, Type II (3) or bulk case in accordance with IEC 60286-6 (3). ASSEMBLY The resistors are suitable for processing on automatic SMD assembly systems. They are suitable for automatic soldering using wave, reflow or vapour phase as shown in IEC 61760-1 (3). Solderability is specified for 2 years after production or requalification, however, excellent solderability is proven after extended storage in excess of 10 years. The permitted storage time is 20 years. The resistors are completely l ead (Pb)-free, the pure tin plating provides compatibility with lead (Pb)-free soldering processes. The immunity of the plating against tin whisker growth has been proven under extensive testing. The encapsulation is resistant to all cleaning solvents commonly used in the electronics industry, including alcohols, esters and aqueous solutions. The suitability of conformal coatings, if applied, shall be qualified by appropriate means to ensure the long-term stability of the whole system. All products comply with the GADSL (1) and the CEFIC-EECA-EICTA (2) list of legal restrictions on hazardous substances. This includes full compliance with the following directives: 2000/53/EC End of Vehicle Life Directive (ELV) and Annex II (ELV II) 2011/65/EU Restriction of the use of Hazardous Substances Directive (RoHS) 2002/96/EC Waste Electrical and Electronic Equipment Directive (WEEE) APPROVALS The resistors are approved wit hin the IECQ-CECC Quality Assessment System for Electronic Components to the detail specification EN 140401-803 which refers to EN 60115-1, EN 140400 and the variety of environmental test procedures of the IEC 60068 (3) series. Conformity is attested by the use of the CECC logo ( ) as the mark of conformity on the package label. Vishay Beyschlag has achieved “Approval of Manufacturer” in accordance with IEC QC 001002-3, clause 2. The release certificate for “Technology Approval Schedule” in accordance with CECC 240001 based on IEC QC 001002-3, clause 6 is granted for the Vishay Beyschlag manufacturing process. The resistors are qualified according to AEC-Q200.
