Stackpole's anti-surge resistors handle pulses up to 10KV



Stackpole Electronics' ASR / SPR Series of anti-surge metal-film resistors are designed to withstand high voltage pulses. Working voltage for the ASR and SPR ranges from 1150 to 4000 volts with overload voltage from 1500 to 5000 volts. In addition, the ASR / SPR can handle high voltage capacitor discharges from 3KV for the smaller sizes up to 10KV for the larger. The ASR and SPR resistors also feature outstanding single and repetitive square pulse handling when compared to standard film resistors. The ASR and SPR Series are an ideal lower cost replacement for ceramic composition and carbon composition resistors where the pulse voltage capability of the resistor is critical or where the inherent inductance of wirewounds is undesirable. In addition, this series is popular for high voltage power supplies, medical applications, plasma cutters, test systems, and circuit protection. The ASR Series is available in resistance values from 10 ohm to 12 Mohm. The SPR Series is UL 1676 rated and is available in values from 1 to 12 Mohm. Power ratings range from watt to 2 watts and 5% tolerance is standard. Pricing is size and resistance value dependent and ranges from $0.045 to $0.22 each in full reel quantities.
