INTRODUCTION

Bulk Metal

Foil (BMF) technology outperforms all other

resistor technologies available today for applications that

require high precision and high stability.

This technology has been pioneered and developed by

Vishay Foil Resistors (VFR), and products based on this

technology are the most suitable for a wide range of

applications. BMF technology allows the production of

customer-oriented products, designed to satisfy specific

challenging technical requirements.

The RCK series of BMF resistors 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 RCK series is 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. The standard design of

these resistors provides a unique combination of

characteristics found in no other single resistor.

VFR's application engineering department is available to

advise and to make recommendations. For non-standard

technical requirements and special applications, please
