MODEL

This is expressed in picofarads. The

first two digits are the significant figures.

The third is the number of zeros to

follow. Standard capacitance ratings

are in accordance with EIA preferred

At + 85

values listed in the Standard Ratings Tables.

At +125

values listed in the Standard Ratings Tables.

Life Test: Capacitors shall withstand rated DC voltage

applied at + 85°C for 2000 hours or derated DC voltage

applied at + 125°C for 1000 hours.

Following the life test:

1. DCL shall not exceed 125% of the initial requirement.

2. Dissipation Factor shall meet the initial requirement.

3. Change in capacitance shall not exceed ± 5%.
