APPLICATION NOTES:
high voltage which appear between adjacent metal part, resistors should mounted adequate distance from other conductors. Resistors screwed together stick provide assembly which will capable withstanding desired voltage, providing individual resistor subjected greater stress power dissipation than recommended this data sheet. some high voltage applications required immerse components reduce effects corona surface tracking. special lacquer available, suitable immersion transformer SF6. When resistors required potted, preferred encapsulant silicone compound. voltage dividers with resistance section below minimum available value resistor, entirely suitable Series resistor, available down ohm.
