wirewound resistors - knp series

wirewound,resistor

knp series construction consists of a measured length of resistance wire (metal alloy) wound on a core (usually a ceramic). the element assembly is then protected by a coating or enclosure of insulating material (such as: vitreous enamel, silicone, cement, epoxy, etc.). wire-wound knp is typically used where large power dissipation is required and where ac performance is relatively unimportant.
