Made of a durable thermoplastic polyester, the saddle clip is designed to secure the A Series in place while safely withstanding its operat- ing temperatures. Use (2) saddle clips per resistor for extra stability. Dim. (mm) Part No. D H L for Series Color 5911E 20 23 13 AX and AY White 5910E 25 26 15 AZ Black *AZ style is provided with dual terminal wires 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.
