Power Type High Power Resistors Anodized Treatment Gold Filled Aluminium Housed Resistor

These high-power gold-plated aluminum-cased fixed resistors are manufactured using an anodized aluminum alloy shell and a fully welded process. The gold oxide layer on the surface not only enhances their aesthetic appeal but also provides excellent corrosion resistance and thermal conductivity.

The product features a molded, sealed structure design, effectively preventing moisture, shock, and dust accumulation, ensuring stable operation even in harsh environments. This series is specifically developed for high-power applications and can be directly mounted on housings or heat sinks, significantly improving heat dissipation efficiency and extending service life. They are widely used in industrial control, power electronics, and frequency conversion systems.
