Vishay Intertechnology's New Power Metal Strip® Meter Shunt Resistor is Industry's First to Offer Direct PCB Mounting

Features Low Resistance Values Down to 100 µW and 3 W Power Capability in 2908 Size Package

MALVERN, PENNSYLVANIA - Feb. 1, 2011 - Vishay Intertechnology, Inc. (NYSE: VSH) today announced a new Power Metal Strip® meter shunt resistor that is the industry's first with sense leads designed to be soldered directly to the PCB, eliminating the need for costly flexible leads. The WSMS2908 combines a 3 W power capability in the 2908 size package with extremely low resistance values down to 100 µW.

The WSMS2908 meter shunt resistor features a proprietary processing technique that produces extremely low resistance values of 100 µW, 250 µW, 300 µW, 430 µW, and 500 µW. These values allow for increased accuracy in current meter shunt applications for industrial and consumer single- or multi-phase 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 WSMS2908 features a 5-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.
