The ASR Series from Stackpole are high voltage, anti-surge, axial leaded resistors. The ASR uses special film that has working voltage ratings from 1600 VDC for the π watt size, up to 5KV for the 1 watt and mini 2 watt sizes. In addition the ASR is capable of withstanding thousands of high voltage pulses up to 10KV depending on resistance value. Yet the ASR Series is less expensive than comparable metal glaze high voltage resistors making it an ideal solution for high volume applications.
Applications for the ASR include high voltage power supply primary side discharge, lighting ballasts, voltage dividers, robotics, industrial controls, UPS systems, network diagnostic equipment, medical diagnostic and monitoring equipment, EKG and ECG equipment, and high voltage snubber resistors.
