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.
