Vishay Releases New Power Metal Strip® Meter Shunt Resistor

Vishay Intertechnology, Inc. announced a new Power Metal Strip® meter shunt resistor that offers 3W power capability in the 5515 size package, with extremely low resistance values down to 100µΩ.

The WSMS5515 meter shunt resistor features a proprietary processing technique that is said to produce very low resistance values from 100 to 500µΩ, which provide increased accuracy in current meter shunt applications for industrial and residential electronic power meters. The new resistor is said to increase accuracy to help designers meet specific customer requirements and thus provide end users with more accurate metering of electric usage.

Featuring a 4-terminal (Kelvin) connection design, the WSMS5515 features all-welded construction and a high power-to-resistor size ratio. The resistor offers low inductance values of <5nH, a low thermal EMF of <3µV/°C, and an excellent frequency response to 50MHz. 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 six to eight weeks for larger orders. Pricing for U.S. delivery in 10,000-piece quantities is $0.52 per piece.
