135D

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 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.

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.
Following life test:
1. DCL, measured at + 85°C rated voltage, shall not be in excess of the original requirement..
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.
