Overview
Cement resistors are power-type resistors made by winding high-stability alloy wire, encapsulating it in a heat-resistant ceramic shell, and filling the outer layer with flame-retardant insulating cement. The resulting structure is robust, with excellent heat resistance, flame retardancy and mechanical strength — providing stable long-term operation under high loads and harsh conditions. They deliver good thermal performance and a relatively low temperature coefficient, making them well-suited for power dissipation, current limiting and voltage division in critical circuit nodes.
