Vishay Intertechnology, Inc. announced a new Power Metal Strip® meter shunt resistor that combines a 3 W power capability in the 2906 size package with very low resistance values down to 300 µohms.
The WSMS2906 meter shunt resistor features a proprietary processing technique that produces extremely low resistance values from 300 µohm to 660 µohm. 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 WSMS2906 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 < 5 nH and a low thermal EMF of < 3 µV/°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. Pricing for U.S. delivery only is $0.95 each in 50,000-piece quantities.
