Non-inductance Wirewound Resistors - KNPN Series

wirewound,resistor

Token Electronics has introduced a non-inductive version of its standard KNP series, leaded wirewound resistors. The KNPN series offers the expected performance of a wirewound resistor with the added characteristic of vastly improved inductance, making it suitable for high-switching applications. The power of this non-inductive winding is available in standard KNP sizes from 0.5 watts up to 6 watts.

A non-inductively wound wirewound has one winding in one direction and one in the other direction; known as Ayrton Perry winding, and a byproduct of this design is that it creates two resistors in parallel in each device. Because of this, non-inductive wirewounds have an upper resistance range limit of half the value possible with a standard winding. For ease of use, Token Electronics has listed a non-inductive resistance value range on its datasheets along with the standard range.

Full line KNPN non-inductive wire wound products meet RoHS compliant, please contact our sales representative for more information.
