Anti-surge axial leaded resistors for high pulse voltages

20th January 2021

For high pulse voltage, anti-surge axial leaded resistors such as Stackpole’s ASR / ASRM series, offer stable electrical and environmental performance, good pulse handling, and have lower inductance than wirewound resistors. The ASR / ASRM can handle pulse voltage discharges from one to ten kilovolts and are rated for working voltages of up to four kilovolts depending on size and resistance value.

For applications that require an axial leaded pulse handling resistor, there are a few options. Wirewound resistors are a good option for low voltage pulses but will be inductive and costly for higher resistance values. Carbon composition resistors have excellent energy handling and low inductance but poor environmental and electrical stability.

The ASR / ASRM is a good choice for a wide range of power supplies, input protection, and control circuits where electrical conditions require high voltage capability.

Pricing for the ASR / ASRM varies with size and resistance value and ranges from $0.045 to $0.18 each in full package quantities.
