Notes:

1. Test method per MIL-STD-202 unless otherwise indicated.

2. Typical defined as that percent change which will include a minimum of 50% of the measured changes in resistance from a variety of lots

representing various unit sizes and ranges.

3. Values shown are the maximum safe dielectric voltage applied from a V block or foil wrapping which extends the complete body length of the

resistor under test.

4. Percent change after the maximum safe dielectric voltage is applied for 1 minute.
