TOKEN KNP Wirewound Resistors Wirewound Resistors Wirewound Resistors are Getting Economical Solution to Board Population Preview Token has launched its commercial wirewound resistor yet with the introduction of the various package size. Matching price with size to provide an economical solution to board population, Token’s wire wound resistors are available in 15 standard size power ranging from 0.5W to 12.5W, all at 1%, 2%, and 5% tolerance. The KNP series has been designed to give enhanced pulse handling capability and increased flameproof protection. The series is RoHS compliant with Pb-free terminations, and KNP wire-wound series can also be supplied with radial, goalpost or lancet preformed leads. The KNP drive to miniaturise is as widespread within industrial process control and circuit break products as it is in the consumer sector. These resistors are ideal for high reliability industrial application as the technology removes the excessive temperature risk. Produced on a high purity ceramic substrate, the resistor is assembled with interference-fit end caps to which are welded terminations. The resistive element is wound on the substrate and welded to the caps. Flameproof silicone cement coating is applied prior to marking with indelible link. The components are then leadformed, if required. To address your need for technical and economic success in a timely manner, our custom solutions are available. 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. 02 of 03 http://www.token.com.tw/ rfq token.com.tw Version 2010 TOKEN KNP Wirewound Resistors Rated Power Ratio Electrical Performance 100 -55 70 80 155 60 40 20 0 -50 -25 0 25 50 75 100 125 150 175 200 225 250 275 280 Ambient Temperature °C TEST ITEMS Resistance Temp.
