AW121KE Ohmite

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. *AZ style is provided with These resistors are ideal for any application which dual terminal wires is subject to surges, high peak power, or impulse energy. FEATuRES APPlICATIONS Their unique design allows uniform distribution High Surge Energy Motor Drives of energy throughout their structure which results in low thermal stress. The high-temperature, Non-Inductive Power Supplies, UPS solvent-resistant epoxy coating carries a UL94V0 Small Size Power Conversion flammability rating which is suitable for almost any In-Rush Current Limiting environment.
