Cement Resistors are robust, high-temperature resistant, and moisture-resistant high-power resistors widely used in various electronic circuits for current limiting, voltage division, load application, and protection.
This series features a compact design, offering excellent heat dissipation and power handling capacity while maintaining a small size, making it particularly suitable for high-temperature, high-humidity, and high-impact environments.
Internally, alloy resistance wire or metal oxide film elements are used, exhibiting extremely low temperature coefficients and noise characteristics, maintaining linear resistance stability even under sustained high-temperature loads.
With its excellent shock resistance, high-temperature resistance, and long-term reliability, Cement Resistors are indispensable key components in industrial power supplies, motor drives, lighting controls, and consumer electronics.
