Wet Tantalum Capacitors
Tantalum-Case with Glass-to-Tantalum Hermetic Seal For-55°C to + 200°C Operation
FEATURES
Standard and Extended Ratings.
Model 135D tantalum-case tantalum electrolytic capacitors
incorporate the advantages of all the varieties of
electrolytic capacitors and eliminate most of the
disadvantages. These units have a 3 volt reverse voltage
capability at + 85°C and a higher ripple current capability
than any other electrolytic type
with similar combinations of capacitance and case size.
Designed for the aerospace applications, this capacitor
was developed under partial sponsorship of the Marshall
Space Flight Center, National Aeronautics and Space
Administration. The capacitors have a high resistance to
damage from shock and vibration. Extended range ratings
are available.
Model 135D capacitors are commercial equivalents of
Military Style CLR79 and CLR81, designed to meet the
PERFORMANCE CHARACTERISTICS
performance requirements of Military Specification MIL-C-
39006/22/25. Capacitors to meet MIL-C-39006/22/25
should be ordered by part numbers shown in that
specification.
Operating Temperature: - 55°C to + 85°C. (To + 200°C
with voltage derating.)
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.
Capacitance Tolerance: At 120 Hz, + 25°C. ± 20%
standard. ± 10%, ± 5% available as special.
Following life test:
1. DCL, measured at + 85°C rated voltage, shall not be in
excess of the original requirement..
DC Leakage Current (DCL Max.):
2. The equivalent series resistance shall not exceed 150%
of the initial requirement.
3. Change in capacitance shall not exceed 10% from the
initial measurement.
At + 25°C and above: Leakage current shall not exceed
the values listed in the Standard Ratings Tables.
