A Series

PulsEater® Ceramic Composition

Available in E12 Ohmic values

The “A” Series non-inductive, ceramic composite

resistors are designed for a variety of applications

where high energy handling capabilities are crucial.

These resistors are ideal for any application which

is subject to surges, high peak power, or impulse

energy.

Their unique design allows uniform distribution

of energy throughout their structure which results

in low thermal stress. The high-temperature,

solvent-resistant epoxy coating carries a UL94V0

flammability rating which is suitable for almost any

environment.

*AZ style is provided with

dual terminal wires
