Power Type Automotive Resistors Gold Filled Fixed Aluminum Shell Resistor Solder Welding

These high-power, gold-plated aluminum-cased fixed resistors are manufactured using an anodized aluminum alloy housing and a fully welded process. The gold oxide coating not only enhances their aesthetics but also provides excellent corrosion resistance and thermal conductivity.

The molded seal effectively prevents moisture, vibration, and dust, ensuring stable operation in harsh environments. Designed for high-power applications, this series of resistors can be directly mounted on the housing or heatsink, significantly improving heat dissipation efficiency and extending product lifespan. They are widely used in industrial control, power electronics, and frequency conversion systems.
