Product Description
Product Overview
This specification covers Metal Film Fixed Resistors manufactured by CHIAN CHIA ELECTRONIC(HU BEI)CO.,LTD. These resistors meet RoHS requirements for environmentally related substances. The type designation is determined by usage type, rated power, nominal resistance value, tolerance, and form factor. The resistors are constructed with a ceramic core, metal film resistor element, tinned iron cap terminals, and are insulated with electric insulation resin and finished with epoxy resin paint. Indication is by color code.
