Meter Shunt Resistor Features Low Resistance, Handles 3 W of Power in 3124 Package

Thu, 02/02/2012 - 10:26am
metal shunt resistorVishay Intertechnology, Inc. announced a new Power Metal Strip meter shunt resistor that combines a 3 W power capability in the 3124 size package with low resistance values down to 100 µ?. The WSMS3124 allows placement of an electron-beam welded shunt in electrical wattmeters. The design also incorporates a physical shape that results in very low TC characteristics (down to 75 ppm/°C). The WSMS3124 meter shunt resistor features a proprietary processing technique that produces extremely low resistance values from 100 µ? to 750 µ?. These values allow for increased accuracy in current meter shunt applications for industrial and consumer single- or multiphase energy meters. With a tolerance of 5.0 percent, the new resistor provides power companies with more accurate data to determine customer usage and to adjust billing terms. The resistor offers low inductance values of <0.5 nH and a low thermal EMF of < 3 µV/°C. The device is lead (Pb)-free and RoHS-compliant.
