vitreous enamel coated wirewound resistors - knp-ve series

wirewound,resistors,vitreous,enamel,coated

wirewound resistor 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.). wirewound resistors are typically used where large power dissipation is required and where ac performance is relatively unimportant. token provides wirewound resistors (knp-ve).
