01 of 03 version 2010 preview token offers a low-cost alternative commercial metal flm resistor for precision applications. the mf series offers tight tolerances and low tcrs over a wide resistance range and are suitable for applications where long-term stability is paramount. the mf is available in a resistance range of 10 to 1m with a standard resistance tolerance of 1% and a temperature coeffcient of resistance (tcr) of +15/-25ppm/c, although other tolerances and tcr s are available. the resistance element in these devices is a precisely controlled thin flm of metal alloy deposited on a high quality alumina rod. plated caps are force-ftted before the assembly is trimmed using advanced trimming techniques to ensure excellent performance and low electrical noise. leads are welded to the end caps prior to the resistor being coated with epoxy, and colour band marking applied. a variety of standard lead forms are available for use where auto-insertion is not available or practical. this gives the advantage of the value being shown, even if the resistor is machine preformed or auto-inserted. the mf is rohs compliant with 100% lead free, contact us with your specifc needs. mf metal film precision resistors features - low cost, low noise, operating temperature range -55c ~ 155c - precision tighted tolerance available in 0.1%, 0.25%, 0.5%, 1% - pure tin plating provides compatibility with lead (pb)-free and lead containing soldering processes precision metal-film resistors for low-cost uses metal film precision resistors applications - telecom - test and measurement - all general purpose applications t oke n http://www.token.com.tw/ rfq token.com.tw
