Product Description

/ Product Characteristics /

Edgewound resistors are produced from a high quality stainless steel alloy formed into a compact configuration designed for heavy duty power applications. The resistor element strip material is wound on edge into a long spring then installed onto a toothed or smooth ceramic insulating core. Winding the element on edge allows the design to cool very effi ciently when installed in a horizontal confi guration.
