Stackpole – High-energy axial resistors withstand 1kV and 30J

A highly reliable carbon composition resistor range, capable of handling

overload voltages up to 1000V and energy pulses up to 30J in power ratings

to 1W, is now available from Stackpole Electronics.

The RC Series comprises high-energy resistors which are seen as ideal for

applications requiring a highly stable but small resistor device with the

capability to withstand increased peak voltages and high energy pulses.

These are typically required in applications such as defibrillators,

consumer electronics, automotive ignition systems and industrial power

supplies.

“Design engineers continue to demand smaller components that offer high peak

voltage handling and increased energy ratings,” said Kory Schroeder, product

engineering manager, Stackpole. “The RC Series provides engineers with a

cost-effective resistor device that handles more than six times the pulse

energy and twice the limiting element voltage (1000V) of comparably sized

wirewound resistors.”

The carbon composition construction is ´unique´ in that it allows for very

high resistance values, has excellent pulse handling capability, is

inherently non-inductive and yet does not exhibit catastrophic failures

demonstrated by other film and wirewound resistor types, says the company.

The RC Series is available in power ratings of quarter, half and 1W at 70C,

with a maximum overload voltage of 1000V and pulse handling rating of up to

30 Joules. Resistance values range from 1ohm to 20Mohm with tolerances down

to ±5%. Operating temperature range is from -55C to +105C.
