VSHZ, VSCZ (Z-Foil) Vishay Foil Resistors Ultra High Precision Z-Bulk Metal(R) Foil Technology Low Profile Conformally Coated High Precision Resistor with TCR down to 0.05 ppm/C, Tight Tolerance from 0.01 % and Load Life Stability of 0.01 % FEATURES Temperature coefficient of resistance (TCR): 0.2 ppm/C typical (- 55 C to + 125 C, + 25 C ref.) (see table 1) Tolerance: to 0.01 % Power rating: to 300 mW at + 70 C Load life stability: to 0.01 % at 70 C, 2000 h at rated power Resistance range: 5 to 120 k INTRODUCTION Bulk Metal(R) 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.
