New 1W Power Metal Strip resistor in compact 0612 case

Vishay has launched a new 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 WSL0612 combines its high power-to-footprint ratio with extremely low resistance values down to 0.001ohm and stable resistance tolerances to 1%. The advanced construction of the WSL0612 resistor incorporates a solid metal nickel-chrome alloy resistive element with low TCR (< 20ppm/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. The resistor is ideal for all types of current sensing and pulse applications, including switching and linear power supplies, instruments, power amplifiers, and shunts in automotive electronic controls such as engines, brushless DC motors, anti-lock brakes, climate and battery management controls; industrial controls, including down-hole test/measurement equipment for oil/gas well drilling; inverter controls for HVAC systems; and DC/DC converters for servers, VRMs for laptops, and Li-ion battery safety and management. Power Metal Strip resistors feature an all-welded construction that contributes to its superior electrical performance. A proprietary processing technique produces extremely low resistance values ranging from 0.001ohm to 0.003ohm, with tight tolerances of 1% and 5%. The WSL0612 provides low thermal EMF (< 3µV/C) and a temperature range from -65C to +170C. The device is lead (Pb)-free and RoHS-compliant, says the company.
