INTRODUCTION
Bulk Metal® Foil (BMF) technology out-performs all other
Vishay Foil resistors are not restricted to standard values;
specific “as required” values can be supplied at no extra
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.
cost or delivery (e.g. 1K2345 vs. 1K)
Thermal stabilization time < 1 s
Electrostatic discharge (ESD) uꢂ to 2ꢁ ꢀꢀꢀ V
Short time overload: 0.01 %
The BMF provides an inherently low and predictable
Temperature Coefficient of Resistance (TCR) and excellent
load life stability for high precision analog applications.
Maximum working voltage: 300 V
Non-inductive, non-capacitive design
Rise time: 1 ns effectively no ringing
Current noise: < - 42 dB
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.
Voltage coefficient < 0.1 ppm/V
Non-inductive: < 0.08 µH
