Cement resistors are high-power resistors that are resistant to high temperatures and humidity, and are widely used in electronic circuits for current limiting, voltage division, load applications, and protection.

This series features a compact design with excellent heat dissipation and power handling capabilities while maintaining a small size, making it particularly suitable for high-temperature, high-humidity, and high-impact environments.

Internally, they utilize alloy resistance wire or metal oxide film elements, exhibiting extremely low temperature coefficients and noise characteristics, maintaining linear resistance stability even under sustained high-temperature loads.

With their superior 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.

Fully Insulated Construction

The housing uses an insulating cement encapsulation structure, effectively preventing arc discharge and short circuits, suitable for printed circuit board applications with high safety requirements.

Superior Heat Dissipation and Power Load Capacity

High thermal conductivity cement material combined with alloy winding structure ensures rapid heat dissipation and low temperature rise performance, allowing for prolonged operation under high power loads.

Strong Resistance to Humidity and Shock

Tested for humidity, vibration, and shock, it possesses excellent resistance to mechanical stress, ensuring long-term reliability in harsh environments.

Chemical Resistance

The outer shell coating effectively resists chemical solvents and acidic/alkaline gases, extending product lifespan.
