Resistor offers 1W power rating in 0612 case size

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

The advanced construction of the resistor incorporates a solid metal nickel-chrome alloy resistive element with a TCR of less than 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 suited 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, BLDC 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; DC/DC converters for servers; VRMs for laptops; and Li-ion battery safety and management.

Like all Power Metal Strip resistors, the WSL0612 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 to 0.003Ω, with tight tolerances of 1.0 and 5.0%. The device provides thermal EMF of less 3 μV/°C and a temperature range from -65 to +170°C. The device is lead-free, RoHS-compliant and Vishay Green.

Samples and production quantities of the WSL0612 resistor are available now, with a lead time of five to seven weeks for larger orders.
