FEATURES

• Terminations: standard tin/lead (SnPb), 100 % tin (RoHS compliant) available
• Improved reliability through the use of a glass-to-tantalum true hermetic anode seal is the prime feature of the Type 138D sintered anode T ANTALEX® capacitor. This construction offers outstanding resistance to thermal shock.
• Model 138D is the commercial equivalents of Tansitor styles WT, UWT, Mallory-N ACC styles TLX, TXX and Military styles CL66, CL67, CLR65, and CLR69, designed to meet the performance requirements of Military Specification MIL-PRF- 39006/09/21. Capacitors in accordance with military s pecifications should be ordered by their military part numbers. PERFORMANCE CHARACTERISTICS Operating Temperature: - 55 °C to + 85 °C and with voltage derating to two-thirds the + 85 °C rating at + 125 °C. Use of Type 138D capacitors for high temperature applications is recommended. Capacitance Tolerance: At 120 Hz, + 25 °C. ± 20 % standard. ± 10 %, ± 5 % available as special. DC Leakage Current (DCL Max.): At + 25 °C, + 85 °C and + 125 °C: Leakage current shall not exceed the values listed in the Standard Ratings Tables. Life Test: Capacitors are capable of withstanding a 2000 h life test at a temperature of + 85 °C or + 125 °C at the applicable rated DC working voltage. Following the life test: 1. DCL shall not exceed 125 % of the original requirement. 2. The ESR shall not exceed 200 % of the initial requirement. 3. Change in capacitance value shall not exceed the percentages below. a) 6 WVDC Units: + 10 % to - 25 % of initial measurement. b) 8 WVDC and 10 WVDC Units: + 10 % to - 20 % of initial measurement. c) 15 WVDC Units: + 10 % to - 15 % of initial measurement. d) 20 WVDC and above: ± 10 % of initial measurement. * Pb containing terminations are not RoHS compliant, exemptions may apply Available Pb-free RoHS* COMPLIANT

ORDERING INFORMATION

MODEL CAPACITANCE CAPACITANCE TOLERANCE DC VOLTAGE RATING AT + 85 °C CASE CODE TERMINATION RoHS COMPLIANT This is expressed in picofarads. The first two digits are the significant figures. The third is the number of zeros to follow X0 = ± 20 % X9 = ± 10 % X5 = ± 5 % Special Order This is expressed in volts. To complete the three-digit block, zeros precede the voltage rating. A decimal point is indicated by an “R” (6R3 = 6.3 V) See Ratings and Case Codes Table 0 = No outer sleeve 2 = Outer plastic film insulation E3 = 100 % tin termination (RoHS compliant) Blank = SnPb termination (standard design) Note Packaging: The use of formed plastic trays for packaging these axial lead components is standard. Tape and reel is not recommended due to the unit weight. DIMENSIONS in inches [millimeters] CASE CODE BARE TUBE WITH OUTER PLASTIC - FILMINSULATION LEAD LENGTH MAX. WEIGHT (oz./g) D L D (Max.)

Operating Temper ature: Capacitors are designed to operate over the temperature range of - 55 °C to + 125 °C. 2. DC Working Voltage: The DC working voltage is the maximum operating voltage for continuous duty at the rated temperature. 3. Surge Voltage: The surge DC rating is the maximum voltage to which the capacitors should be subjected under any conditions. This includes transients and peak ripple at the highest line voltage. The surge voltage of capacitors rated below 150 V is 115 % of the rated DC working voltage. The surge voltage of capacitors rated at 150 V DC is 165 volts.

3.1 Surge Voltage Test: Capacitors shall withstand the

surge voltage test applied through a 1000 Ω ± 10 % resistor in series with the capacitor and voltage source at the rate of one-half mi nute on, four and one-half minutes off, for 1000 successive test cycles at + 85 °C or + 125 °C. 4. Capacitance Tolerance: The capacitance of all capacitors shall be within the specified tolerance limits of the nominal rating.

bridge method at or referred to, a frequency of 120 Hz at a temperature of + 25 °C. A polarizing voltage shall be used of such magnitude that there shall be no reversal of polarity due to the AC component. The maximum AC voltage will be 1 volt rms applied during measurement. 5. Capacitance Change With Temperature: The capacitance change with temperature shall not exceed the limits given in the Standard and Extended Ratings Table for each capacitor. 6. Equivalent Series Resistance: Measurements shall be made by the bridge method at or referred to, a frequency of 120 Hz at a te mperature of + 25 °C. A polarizing voltage shall be used of such magnitude that there shall be no reversal of polarity due to the AC component. The maximum AC voltage will be 1 V rms applied during measurement.

6.1 The equivalent series resistance shall not exceed the

maximum value in ohms listed in the Standard and Extended Ratings Table for each capacitor.

6.2 The dissipation factor may be calculated from the

equivalent series resistance and capacitance values as shown: where: DF = Dissipation Factor in % R = ESR in ohms C = Capacitance in µF f = frequency in Hz At 120 Hz, the above equation becomes: TYPICAL CURVES OF IMPEDANCE AS A FUNCTION OF FREQUENCY AT VARIOUS TEMPERATURES - 55 - 40 - 20 + 25 + 85 IMPEDANCE IN (Ω) 0.2 1.0 100 200 FREQUENCY IN Hz 100 1K 10K 100K 1M 10M “K” Case 120 µF, 25 V Capacitors °C125 °C - 55 - 40 - 20 + 25 + 85 +125 FREQUENCY IN Hz IMPEDANCE IN (Ω) 100 1K 10K 1 00K 1 M 10M 0.2 1.0 100 200 “C” Case 10 µF. 100 V Capacitors UP TO + 85 °C WORKING VOLTAGE (V) AT + 125 °C WORKING VOLTAGE (V) UP TO + 85 °C WORKING VOLTAGE (V) AT + 125 °C WORKING VOLTAGE (V) 6 4 35 22 8 5 50 30 10 7 60 40 15 10 75 50 20 13 100 70 25 15 125 85 30 20 150 100 DF 2πfRC DF RC×

Leakage Current: Measurements shall be made at the applicable rated working voltage at + 25 °C ± 5 °C through application of a steady source of power, such as a regulated power supply. The total resistance in series with each capacitor shall be between 1000 Ω and 10 000 Ω. The voltage shall be applied to the capacitor for 5 minutes before making the leakage current measurement.

7.1 The maximum leakage current for any capacitor shall

not exceed the value in microamperes listed in the Standard and Extended Ratings Table for each capacitor. Note: leakage current varies with applied voltage. See graph below for the appropriate adjustment factor. 8. Low Temperature Impedance: The impedance of any capacitor at - 55 °C at 120 Hz, shall not exceed the values given in the Standard and Extended Ratings Tables. 9. Life Test: Capacitors are capable of withstanding a 2000 h life test at a temperature of + 85 °C or + 125 °C at the applicable rated DC working voltage. 10. High Frequency Vibration: Capacitors shall with stand vibration from 10 Hz to 2000 Hz at 20 g when tested. 11. Lead Pull Test: Capacitors shall withstand a lead tensile stress of 3 pounds (13.2 N) for 30 s, applied axially. 12. Marking: Capacitors shall be marked with Sprague and/or the Sprague trademark 2, the Sprague type (138D); rated capacitance and tolerance (the tolerance shall be coded, using the list shown in How to Order); rated DC working voltage at + 85 °C; the standard EIA date code of manufacture. GUIDE TO APPLICATION 1. Ripple Current: All capacitors will withstand rms ripple currents as listed for each capacitor.

1.1 The rms ripple current rating is independent of

temperature or frequency within the following limitations:

1.1.1 At frequencies of less than 120 Hz, the rated rms ripple

current must be multiplied by the factors shown:

1.1.2 The sum of the peak AC voltage plus the DC voltage

shall not exceed the DC working voltage of the capacitor.

1.1.3 The sum of the negative peak AC voltage, plus the

applied DC voltage shall not allow a voltage reversal. 2. Cleaning wiring boards with Type 138D capacitors: Customary cleaning solvents used in the electronics industry at present will not affect Type 138D capacitors. However, the use of ultrasonic cleaning techniques is not recommended under any circumstances. 3. Apparent Capacitance: Note that in timing circuit applications, the circuit designer must take into account two important variables which affect any electrolytic capacitor. T hese are the internal leakage resistance of the capacitor and its dielectric absorption, which will depend on the elapsed time since the capacitor was last energized. In applications where electrolytic capacitors are subjected to DC energy, or in effect, extremely low frequencies, the value of the apparent capacitance will be somewhat higher than that which is measured at 120 Hz. 4. No Reverse Voltage: The application of reverse voltage to these capacitors will cause internal damage. The resulting damage will lead to immediate or delayed failure of the unit. This will take the form of a catastrophic short circuit with possible expulsion of the electrolyte.
