1ꢂ For 0ower rating above 7ꢀꢁC% see derating curveꢂ
2ꢂ Voltage rating shown is the rated DC continuous working voltage or the sine-wave RMS absolute maximum voltage at commercial line fre-
quencyꢂ For DC a00lications the absolute maximum 0ermissible voltage is 1ꢂ5 times the value shown for low re0etition short-time-overload or
0ulse conditions of 1ꢀ seconds or less durationꢂ
3ꢂ Contact factory for higher resistance valuesꢂ
4ꢂ For CGH-1 and 2 above 5ꢀꢀ meg and CGH-3 and 5 above 1ꢀꢀꢀM only 2 and 5ꢃ tolerance and 1ꢀꢀ 00m/ꢁC TCR availableꢂ
5ꢂ Ty0ical voltage coefficient of resistance is -1 to -2 00m/V measured at fulll rated voltage and 1ꢀꢃ rated voltageꢂ
