Glazed Wirewound Resistor

Glazed wirewound resistor is also known as vitreous enamel coated wirewound resistor, a classic high stability power resistor produced by Guangdong Qingda Electronic Technology Co., Ltd. It winds high-temperature alloy resistance wire onto a solid ceramic core, then adopts high-temperature vitreous glaze sintering process to form a hard glazed protective layer.

The dense glazed coating provides outstanding insulation, moisture-proof, dust-proof and anti-corrosion capability. It can work steadily under continuous high temperature environment with tiny resistance drift and strong overload resistance. Compared with ordinary coated wirewound resistors, the vitreous glaze layer has better heat resistance and mechanical scratch resistance, which effectively protects the internal resistance wire from oxidation and damage in long-term operation.

 Key Features

- Vitreous enamel glazed sintered protective coating
- High-temperature alloy wire wound on solid ceramic core
