1 / 4 page Ultra High Precision Foil Wraparound Surface Mount Chip Resistor with TCR of ± 0.05 ppm/°C and Power Coefficient of 5 ppm at Rated Power and Load Life Stability of ± 0.005 % (50 ppm) Document Number: 63060 For any questions, contact: foil@vishay.com www.vishay.com Revision: 24-Mar-09 1 VSMP Series (0805, 1206, 1506, 2010, 2512) (Z-Foil) Vishay Foil Resistors INTRODUCTION VSMP Series is the industry’s first device to provide high rated power, excellent load life stability along with extremely low TCR all in one resistor. One of the most important parameters influencing stability is the temperature coefficient of resistance (TCR). Although the TCR of foil resistors is considered extremely low, this characteristic has been further refined over the years. The VSMP Series utilizes ultra high precision Bulk Metal® Z-foil. The Z-foil technology provides a significant reduction of the resistive element’s sensitivity to ambient temperature variations (TCR) and to self heating when power is applied (power coefficient). Along with the inherently low PCR and TCR, Z-foil technology also provides remarkably improved load life stability, low noise and availability of tight tolerance. The VSMP has a full wraparound termination which ensures safe handling during the manufacturing process, as well as providing stability during multiple thermal cyclings.
