Wirewound Resistors - KNP Series

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.
