WIREWOUND RESISTORS
Vitreous Enamel Power Wirewound Resistors
KNP-VE
The KNP-VE Series of vitreous enamel coated power resistors from Tokenchina offers a cost-competitive alternative to silicon cement coated types over the 2.5W to 12W power range with resistance values 1Ω to 39KΩ. Advantage of these vitreous enamelled devices is that Ayrton-Perry windings can be used to give low-inductance resistors within the same package dimensions. Tokenchina's KNP-VE series is lead-free and RoHS compliant. Detailed specifications, both mechanical and electrical, please contact our sales representative for more information. Features
