Notes:
1. For power rating above 70°C, see derating curve.
2. Voltage rating shown is the rated DC continuous working voltage or the sine-wave RMS absolute maximum voltage at commercial line fre-
quency. For DC applications the absolute maximum permissible voltage is 1.5 times the value shown for low repetition short-time-overload or
pulse conditions of 10 seconds or less duration.
3. Contact factory for higher resistance values.
4. For CGH-1 and 2 above 500 meg and CGH-3 and 5 above 1000M only 2 and 5% tolerance and 100 ppm/°C TCR available.
5. Typical voltage coefficient of resistance is -1 to -2 ppm/V measured at fulll rated voltage and 10% rated voltage.

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.
