Cement resistors are high-power resistors characterized by high temperature resistance, moisture resistance, and robust construction, widely used in current limiting, voltage dividing, load, and protection circuits.

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

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

With their excellent shock resistance, heat resistance, and long-term reliability, cement resistors are widely used 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.
