VSMP Series (0603, 0805, 1206, 1506, 2010, 2512) VSMP Series (0603, 0805, 1206, 1506, 2010, 2512) (Z Foil) (Z Foil) Ultra High PrUltra High Precision Foil Wecision Foil Wraparraparound Surface Mount Chip Resistoround 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) FEATURES Temperature coefficient of resistance (TCR): 0.2 ppm/C typical (55C to +125C, +25C ref.) Resistance tolerance: to 0.01% Power coefficient R d ue to self heating: 5 ppm at rated power Power rating: to 750 mW at +70C (see table 3) Load life stability: to 0.005% at 70C, 2000 h at rated power Resistance range: 5 to 125 k (for lower or higher Top View (for date code print specification please refer to table 2) values, please contact us) Bulk Metal Foil resistors are not restricted to standard values, we can supply specific as required values at no extra cost or delivery (e.g. 1K2345 vs. 1K) INTRODUCTION Thermal stabilization time <1 s (nominal value achieved within 10 ppm of steady state value) VSMP Series is the industrys first device to provide high rated power and excellent load life stability along with Electrostatic discharge (ESD) at least to 25 kV extremely low TCR all in one resistor. Short time overload: 0.005% One of the most important parameters influencing stability Non inductive, non capacitive design is the Temperature Coefficient of Resistance (TCR). Rise time: 1 ns effectively no ringing Although the TCR of Bulk Metal Foil is considered Current noise: 0.010 V /V of applied voltage RMS extremely low, this characteristic has been further (<40 dB) refined over the years. The VSMP Series utilizes ultra Voltage coefficient <0.1 ppm/V high precision Z Foil. The Z Foil technology provides a (resistance values above 10 k) significant reduction of the resistive elements sensitivity to ambient temperature variations (TCR) and to self Non inductive: <0.08 H heating when power is applied (Power Coefficient of Non hot spot design Resistance, or PCR). Along with the inherently low PCR Terminal finishes available: lead (Pb)-free, tin/lead alloy and TCR, Z Foil technology also provides remarkably Matched sets are available on request improved load life stability, low noise and tight tolerances. Screening in accordance with EEE-INST-002 and Vishay Foil Resistors (VFR) application engineering MIL-PRF-55342 available (see datasheet resistor department is available to advise and make models 303133 to 303138) recommendations.
