Vishay Intertechnology, Inc. today launched a surface-mount Power Metal Strip® resistor with a wide side terminal construction that yields a high 1W power rating in the compact 0612 case size. The new WSL0612 combines its high power-to-footprint-size ratio with extremely low resistance values down to 0.001 Ω and stable resistance tolerances to 1.0%.

The advanced construction of the WSL0612 resistor incorporates a solid metal nickel-chrome alloy resistive element with low TCR (< 20 ppm/degree C). This results in a high-power resistor in the 0612 package size that maintains the superior electrical characteristics of the Power Metal Strip construction. The device’s small size allows for the design of high-power circuits featuring the smallest possible resistor for higher-performance end products.

Like all Power Metal Strip resistors, the device released today features an all-welded construction that contributes to its superior electrical performance. A proprietary processing technique produces extremely low resistance values ranging from 0.001 Ω to 0.003 Ω, with tight tolerances of 1.0% and 5.0%. The WSL0612 provides low thermal EMF (< 3 μV/degree C) and a temperature range from -65 to +170 degrees C. The device is lead (Pb)-free, RoHS-compliant, and Vishay Green. Samples and production quantities of the new resistor are available now, with a lead time of five to seven weeks for larger orders. Pricing for U.S. delivery only starts at $0.12 per piece in 50,000-piece quantities.
