Product Overview
The MOS and MOSX series are compact power resistors featuring metal oxide film or metal film construction, respectively. These resistors are designed for high reliability and offer a flame-retardant coating (equivalent to UL94 V-0). They are suitable for automatic insertion and various forming processes, including surface mount technology. Compliant with EU RoHS directives, these resistors are ideal for applications requiring compact size and robust performance.
