CMP series is a high power anti surge thick film chip resistor. Thick film chip resistor is made of a thick film resistive layer printed onto a ceramic substrate. The thick film resistive layer is a mixture of metal oxides. Surface mount chip resistors have electroplated tin (Sn) outer terminations for board soldering. The resistive element is protected by an epoxy overcoat layer. Typical applications include power supplies, digital meters, consumer electronics, LED lighting and industry control boards.
