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 Vishay Foil Resistors are manufactured with any resistance value within given resistance range (e.g. 1 kΩ or 1.1234 kΩ) 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.
