Utilising high voltage power film to achieve high working voltages and high overload voltages, the ASR/ASRM series of anti-surge resistors has been released by Stackpole. The devices withstand repeated high voltage pulses of up to 10KV every 5 seconds with very little resistance shift.
The resistors are suitable for LED and lighting, instrumentation and test, audio, security, HVAC applications. The ASR and ASRM are available in sizes ranging from mini ¼ watt up to mini 2 watts. Prices range from $0.045 to $0.22 each in full reel quantities.
