VSH, VSC
Vishay Foil Resistors
Bulk Metal® Foil Technology Low Profile Conformally Coated High
Precision Resistor with Tight Tolerance from ± 0.01 % and Load Life
Stability of ± 0.01 % and Instantaneous Thermal Stabilization
FEATURES
INTRODUCTION
Bulk Metal® Foil (BMF) technology out-performs all other
resistor technologies available today for applications that
require high precision and high stability, and allows
production of customer oriented products designed to satisfy
challenging and specific technical requirements.
The BMF provides an inherently low and predictable
Temperature Coefficient of Resistance (TCR) and excellent
load life stability for high precision analog applications.
Model VSH offers low TCR, excellent load life stability, tight
tolerance, excellent shelf life stability, low current noise and
low voltage coefficient, all in the same resistor.
Our application engineering department is available to
advise and make recommendations. For non-standard
technical requirements and special applications, please
