Aluminum Housed Wirewound Resistors

Aluminum Housed Wirewound Resistors
power:5w
Size: 31*1.5mm
Resistance Range:0.51*1.0k
Dissipate Heat Area:410mm²
The Chief Characteristic: Due to use metal aluminum shell radiator therefore they are possess small value high power load. Due to the adoption of silicone resin or silica sand encapsulation,The products with good insulation performance and the ideal thermal conductive function, Suitable for Cooling plate installaton.

The Chief Purpose of aluminum housed wirewound resistors:


Used in DC or low frequency AC circuits. If used in high frequency circuit, it shall order non-inductive resistor, need to declare when you order it, non-inductive resistor with "N" in front of the product logo.
