Delivering 10 W power rating with an ultra-low resistance of 0.007 ohm (7 mOhm), it is designed for the most demanding high-current sensing applications in electric vehicles, industrial inverters, and server power supplies. The metal strip construction provides very low inductance for accurate high-frequency current measurement. The +\/-1% tolerance and +\/-75 ppm\/degC TCR ensure precision across the -65 to +170 degC operating range. AEC-Q200 qualified for automotive reliability requirements.","working_principle":"The WSHP28187L000FEA operates as a precision shunt resistor for high-current measurement. The 0.007 ohm resistance generates 7 mV per ampere of current flow, providing a measurable voltage drop while minimizing power loss in high-current paths. The 2818 package provides sufficient pad area for the 10 W power dissipation with excellent thermal management. The metal strip element welded between copper terminals provides stable, low-inductance current sensing even during fast switching transients. The improved thermal management incorporated into the WSHP series design enables higher power density compared to standard WSL packages.","pin_description":"
