Vishay Intertechnology's New Power Metal Strip® Meter Shunt Resistor Features Very Low Resistance Values Down to 300 Micro-Ohms and 3 W Power Capability in 2906 Size Package

MALVERN, PA--(Marketwire - Feb 16, 2012) - Vishay Intertechnology, Inc. (NYSE: VSH) today 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 µΩ.

The WSMS2906 meter shunt resistor features a proprietary processing technique that produces extremely low resistance values from 300 to 660 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 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 less than 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 Power Metal Strip resistors at
