The new surface-mount Power Metal Strip® resistor in the 2010 case size combines a high 2 W power rating with extremely low resistance values down to 0.001 ohms and stable resistance tolerances to 0.5 %. The advanced construction of the WSLP2010 resistor incorporates a solid metal nickel-chrome or manganese-copper alloy resistive element with low TCR (less than 20 PPM/°C). This results in a high-power resistor with an operating temperature range of - 65 °C to + 170 °C while maintaining the superior electrical characteristics of the Power Metal Strip construction.

The new device allows for the design of high-power circuits featuring the smallest possible resistor for higher-performance end products. Furthermore, the resistor's high-temperature capability allows the use of the WSLP2010 in harsh high-temperature environments without sacrificing power rating or electrical performance. The WSLP2010 will meet the requirements of AEC-Q200.
