3 W shunt resistors down to 100 μΩ
28 May 2008
Passive Components
Vishay has announced a new Power Metal Strip meter shunt resistor that offers 3 W capability in the 5515 size package, with extremely low resistance values down to 100 μΩ.
The WSMS5515 resistor features a proprietary processing technique that produces very low resistance values from 100 μΩ to 500 μΩ, which provide increased accuracy in current meter shunt applications for industrial and residential electronic power meters.
Featuring a 4-terminal (Kelvin) connection design, the resistor features all-welded construction and a high power-to-resistor size ratio. The resistor offers low inductance values of less than 5 nH, a low thermal EMF of less than 3 μV/°C, and an excellent frequency response to 50 MHz. The device is lead-free and RoHS-compliant.
