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.
