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 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 coef cient of resistance is -1 to -2 ppm/V measured at fulll rated voltage and 10% rated voltage.
