VCS1625 Vishay Foil Resistors High Precision Bulk Metal Foil Surface Mount Current Sensing Chip Resistor with TCR of 2 ppm/C and Load Life Stability of 0.02 % FEATURES Temperature coefficient of resistance (TCR): 2.0 ppm/C typical (- 55 C to + 125 C, + 25 C ref.) (see table 1) Resistance range: 0.01 to 10 (for higher or lower values please contact us) Vishay Foil resistors are not restricted to standard values, we can supply specific as required values at no extra cost or delivery (e.g. 1.2345 vs. 1 ) Tolerance: to 0.1 % INTRODUCTION Load life stability: 0.02 % at 70 C, 2000 h at rated power Model VCS1625 is a surface mount resistor designed with Electrostatic discharge (ESD) up to 25 000 V 4 pads for Kelvin connection. Utilizing Vishay Bulk Metal Short time overload 0.005 % foil as the resistance element, it provides performance Non inductive, non capacitive design capabilities far greater than other resistor technologies can Power rating: 0.5 W at + 70 C (figure 1) or 5 A, whichever supply in a product of comparable size. is lower This small device dissipates heat almost entirely through the Thermal EMF: 0.05 V/C typical pads so surface mount users are encouraged to be generous Non hot spot design with the boards pads and traces. Gold terminations are Current noise: < - 40 dB available on special order. Rise time: 1 ns effectively no ringing Voltage coefficient: < 0.1 ppm/V Our application engineering department is available to Non inductive: < 0.08 H advise and to make recommendations. For non standard For better performances please review VCS1625Z (Z-foil) technical requirements and special applications, please datasheet contact us. TERMINATIONS Two lead (Pb)-free options are available: (1) gold plated or tin plated FIGURE 1 - POWER DERATING CURVE Tin/lead plated - 55 C + 70 C 100 APPLICATIONS Electrical Schematic Automatic test equipment (ATE) 75 I E Airborne (in heads-up display systems) 1 1 50 High precision instrumentation R Electron beam recording equipment 25 Electron microscopes E I2 2 0 Current sensing applications - 75 - 50 - 25 0 + 25 + 50 + 75 + 100 + 125 + 150 + 175 Forced balance electronic scales Ambient Temperature (C) Applications that require superior frequency stability Note Military (1) Power rating at + 70 C: 0.5 W on FR4 PCB Medical TABLE 1 - TOLERANCE AND TCR VS.
