Wirewound resistors - KNP and KNPN 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.). Wirewound KNP/KNPN is typically used where large power dissipation is
required and where AC performance is relatively unimportant. Token
wirewound provides KNP normal type, and KNPN non-inductive type.
