TOKEN KNP-VE Wirewound Resistors Vitreous Enamel Coated Wirewound Resistors Vitreous Enamel Coated Power High Energy Wirewound Resistors Preview The KNP-VE Series of vitreous enamel coated power resistors from Token offers a cost-competitive alternative over the 2.5W-12W power range. The range is available with resistance values of 1Ω to 39KΩ in power ratings of 2.5W, 3W, 5W, 6W, 8W, 9W and 12W (at 25°C), and with body sizes that match the industry standards. Vitreous enamelled resistors were introduced at a time when alternative directly applied coatings could not withstand the thermal stresses caused by the resistors’ high body temperatures. Token offers the durability of a lead free conformal vitreous enamel coating, permits the KNP-VE Series resistors to maintain a hard coating while operating at high temperatures. Mechanical integrity is enhanced by the all-welded construction. Power KNP-VE Wirewound Series are ideal for computer, communications and industrial applications in which cost, quality, and reliability are key considerations. The KNP-VE series is RoHS compliant and Ayrton Perry noninductive windings are available on request. To address your need for technical and economic success in a timely manner, our custom solutions are the best choise. Contact us with your specific needs.

Sometimes the gauge is extremely thin (finer than a strand of human hair) and very susceptible to breakage in environments containing salts, ash, dust and corrosives. Avoid utilization in such environments. ● Do not install in dusty areas because the accumulation will cause shorts and poor conductance.
