In devices such as frequency converters, automotive LED lights, and professional audio equipment, there lies a key "guardian" - the high power AH gold aluminum housed wire wound resistor. 

So, what is wire wound resistor made of?

It features a stable framework of high-temperature resistant ceramic rod, wrapped with high-quality alloy wire as the resistance core. It is then precision-potted with high-insulation paste and paired with an aluminum alloy housing that combines heat dissipation and protection, ensuring stable performance and enhanced operational safety. 

But what characteristics make it stand out?

• High rated power and ultra-precision (accuracy up to ±1%).

• Excellent stability with weather resistance and reliable performance. The aluminum alloy housing not only dissipates heat quickly but also isolates external dust and moisture.

• Wide power range, offering 6 models (5 to 250 watts) to adapt to different power scenarios.

• Resistance Tolerance: ±10%, ±5%, ±3%, ±2%, ±1%, ±0.5%.

• Superior heat dissipation, operating temperature range from -55℃ to +275℃.

• Taking the 50W wire wound resistor for TUBE AMP AUDIO in the following figure as a reference, its resistance range is 0.1ohm ~ 100Kohm.
