MALVERN, PA — (Marketwire) — 02/02/12 — Vishay Intertechnology, Inc. (NYSE: VSH) today announced a new Power Metal Strip® meter shunt resistor that combines a 3 W power capability in the 3124 size package with extremely low resistance values down to 100 micro-ohms. 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 to 750 micro-ohms. 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 %, the new resistor provides power companies with more accurate data to determine customer usage and to adjust billing terms.
The WSMS3124 features a five-terminal connection design and an all-welded construction that contributes to its superior electrical performance. The resistor offers very low inductance values of less than 0.5 nH and a low thermal EMF of less than 3 microvolts/°C. The device is lead (Pb)-free and RoHS-compliant.
Samples and production quantities of the new meter shunt resistor are available now, with a lead time of eight to 10 weeks for larger orders. Follow resistors from Vishay at .
