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 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.
