VCS1625P Vishay Foil Resistors High Precision Surface Mount Current Sensing Chip Resistor with Power Rating to 1 W, Temperature Coefficient of Resistance of : ± 2 ppm/°C and Load Life Stability of ±0.015% FEATURES NEW INTRODUCTION Model VCS1625P is a surface mount resistor designed with 4 pads for Kelvin connection. Utilizing VFR’s (Vishay Foil Resistors’) Bulk Metal® Foil as the resistance element, it provides performance capabilities far greater than other resistor technologies can supply in a product of comparable size. The key performance of the new VCS1625P is its high rated power up to 1W. This small device dissipates heat almost entirely through the pads so surface mount users are encouraged to be generous with the board’s pads and traces. Gold terminations are available on special order. The four terminal device separates the current leads from the voltage sensing leads. This configuration eliminates the effect of the lead wire resistance from points A to B and C to D, allowing low TCR current sensing. VFR’s application engineering department is available to advise and to make recommendations. For non-standard technical requirements and special applications, please contact foil@vishaypg.com.

This calls for more than just selecting a standard device and applying it to a circuit. The standard device may turn out to be all that is needed but an analysis of the projected service conditions should be made and it may well dictate a routine of stabilization known as post manufacturing operations or PMO. The PMO operations that will be discussed are only applicable to Foil resistors. They stabilize Foil resistors while they are harmful Document Number: 63216 Revision: 28-Aug-12 to other types. Short time overload, accelerated load life, and temperature cycling are the three PMO exercises that do the most to remove the anomalies down the road. Foil resistors are inherently stable as manufactured. These PMO exercises are only of value on foil resistors and they improve the performance by small but significant amounts. Users are encouraged to contact VFR’s application engineering department for assistance in choosing the PMO operations that are right for their application.
