This technology has been pioneered and developed by VISHAY, and products based on this technology are the most suitable for a wide range of applications. BMF technology allows us to produce customer orientated products, designed to satisfy challenging and specific technical requirements. Models RS92N, RS92NA, and AN made from Vishay BMF offers low TCR, excellent load life stability, tight tolerance, fast response time, low current noise, low thermal EMF and low voltage coefficient, all in one resistor. The RS92N, RS92NA, and AN are virtually insensitive to destabillizing factors. The resistor element is a solid alloy that displays the desirable bulk properties of its parent material, thus it is inherently stable and noise free. Vishay's Bulk Metal(R) RS92N, RS92NA, and AN resistors are the modern generation of precision resistors. The standard design of these resistors provides a unique combination of characteristics found in no other single resistor. Our Application Engineering Department is available to advise and to make recommendations. For non-standard technical requirements and special applications, please contact us.
