Notes:

1. For power rating above 70C, see derating curve.

2. Voltage rating shown is the rated DC continuous working voltage or the sine-wave RMS absolute maximum voltage at com-

mercial line frequency.

3. Marked per MIL-R-49462

4. Values greater than 100 meg and less than 500 meg, ±200ppm; values greater than or equal to 500 meg, ±500ppm.
