波浪型功率電阻器(DQ 系列)






Nonflammable Wave - Shape Ribbon Wirewound DQ Series
A tubular ceramic has two terminals and is wound with a resistance element consisting of a wave-shaped alloy ribbon. Non-flammable resin insulation is applied after cooling and drying through a temperature process and then the component mounts are attached. The resistance value range is relatively low due to alloy material limitations; see the DR series if upper resistance values are required.

This product supports the use of numerous taps, has is low impedance, and can be fabricated in various shapes to support a wide range of applications. The DQ series is suitable for educational modeling applications, load testing, industrial machinery, electric power distribution, instruments, automation control installations, etc. For custom specifications, please contact us to discuss the details.
