1. Compact dimensions with excellent stability in high-temperature environments, resistant to humidity and shock
2. Fully insulated design ideal for printed circuit board applications
3. Exceptional heat dissipation with minimal linear temperature coefficient
4. Instant overload capability with low noise figures and minimal annual resistance value drift
Cement resistors are high-power resistors with a robust structure, high temperature resistance, and moisture resistance, 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 in 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 resistance values even under sustained high-temperature loads.
With excellent shock resistance, heat resistance, and long-term reliability, they are widely used in industrial power supplies, motor drives, lighting control, and consumer electronics.
