138D Vishay Wet Tantalum Capacitors Sintered Anode TANTALEX® Capacitors Hermetically-Sealed with True Glass-to-Tantalum Seal FEATURES • Terminations: standard tin/lead (SnPb), 100 % tin (RoHS compliant) available Pb-free • Improved reliability through the use of a Available glass-to-tantalum true hermetic anode seal is RoHS* the prime feature of the Type 138D sintered COMPLIANT anode TANTALEX® capacitor. This construction offers outstanding resistance to thermal shock. • Model 138D is the commercial equivalents of Tansitor styles WT, UWT, Mallory-NACC 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 specifications should be ordered by their military part numbers. PERFORMANCE CHARACTERISTICS 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. 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.

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 4. 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 minute on, four and one-half minutes off, for 1000 successive test cycles at + 85 °C or + 125 °C. Capacitance Tolerance: The capacitance of all capacitors shall be within the specified tolerance limits of the nominal rating. www.vishay.com 22 4.1 Capacitance measurements shall be made by the 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 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 Vrms 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: DF = 2πfRC -----------------4 10 where: DF = Dissipation Factor in % R = ESR in ohms C = Capacitance in µF f = frequency in Hz At 120 Hz, the above equation becomes: R×C DF = -------------13.26 For technical questions, contact: [email protected] Document Number: 40025 Revision: 17-Mar-08 138D Wet Tantalum Capacitors Sintered Anode TANTALEX® Capacitors Hermetically-Sealed with True Glass-to-Tantalum Seal Vishay PERFORMANCE CHARACTERISTICS (Continued) For example, percent dissipation factor of a 30 µF, 6 V capacitor, which has a maximum ESR of 3.4 Ω at + 25 °C and 120 Hz, would be calculated as shown: 2π × 120 × 3.4 × 30 × 30 DF = -------------------------------------------------= 3.4 --------------------- = 7.7 % 4 13.26 10 7. 7.1 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. 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. LEAKAGE AS A FUNCTION OF VOLTAGE & TEMPERATURE 9. 10. 11. 12. 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: 1.0 0.8 0.7 0.6 0.5 0.4 FREQUENCY IN HERTZ LEAKAGE CURRENT FACTOR 0.3 0.2 25 50 60 100 0.36 0.59 0.65 0.88 1.1.2 The sum of the peak AC voltage plus the DC voltage shall not exceed the DC working voltage of the capacitor. 0.1 0.08 0.07 0.06 0.05 0.04 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. These 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. 0.03 0.02 0.01 0.008 0.007 0.006 0.005 0.004 0.003 0.002 0.001 0 10 20 30 40 50 60 70 80 90 100 PERCENT OF RATED VOLTAGE 8. 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. High Frequency Vibration: Capacitors shall with stand vibration from 10 Hz to 2000 Hz at 20 g when tested. Lead Pull Test: Capacitors shall withstand a lead tensile stress of 3 pounds (13.2 N) for 30 s, applied axially. 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.
