Small-sized resistors handle big peaks and pulses

New highly reliable carbon composition resistors are capable of handling overload voltages up to 1000V and energy pulses up to 30J in power ratings to 1W.

The RC Series of highly reliable carbon composition resistors from Stackpole Electronics are capable of handling overload voltages up to 1000V and energy pulses up to 30J in power ratings to 1W.

Designated the RC Series, these high-energy resistors are ideal for applications requiring a highly stable, but small resistor device with the capability to withstand increased peak voltages and high energy pulses, which are 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 for Stackpole.

"The RC Series provides engineers with a cost effect resistor device that handles more than six times the pulse energy and twice the limiting element voltage (1000V) of comparably sized wire-wound resistors".

The RC Series' carbon composition construction is novel in that it allows for very high resistance values, has excellent pulse handling capability, is inherently noninductive and yet does not exhibit catastrophic failures demonstrated by other film and wire-wound resistor types.

The RC Series is available in power ratings of 0.25, 0.5 and 1W at 70C, with a maximum overload voltage of 1000V and pulse handling rating of up to 30J.

Resistance values range from 1ohm to 20Mohm with tolerances down to +/-5%.

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

The RC Series pricing is power and tolerance dependent, but $0.08 is typical in quantities of 1000 pieces.

Lead time for the RC Series is 8 to 10 weeks.
