Wirewound Resistors - KNP Series
Wirewound Resistors - KNP Series
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.
