Vishay Foil Resistors

Precision Resistor with Tight Tolerance from ± 0.01 % and Load Life

Stability of ± 0.01 % and Instantaneous Thermal Stabilization

Vishay Foil Resistors are manufactured with any resistance

value within given resistance range (e.g. 1 k

Ω or 1.1234 kΩ)

INTRODUCTION

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

contact us using the e-mail address in the footer below.
