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
