VISHAY 138D Technical data

Wet Tantalum Capacitors

Sintered Anode TANTALEX

®

with True Glass-to-Tantalum Seal

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 120Hz, + 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
hour life test at a temperature of + 85°C or + 125°C at the
applicable rated DC working voltage.

Capacitors Hermetically-Sealed

FEATURES

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

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-PRF­39006/09/21. Capacitors in accordance with military
specifications should be ordered by their military part
numbers.

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) 6WVDC Units: + 10% to - 25% of initial measurement.
b) 8WVDC and 10WVDC Units: + 10% to - 20% of initial

measurement.

c) 15WVDC Units: + 10% to - 15% of initial measurement.
d) 20WVDC and above: ± 10% of initial measurement.
