Microhm Electronics' MMS8518 power metal strip shunt resistors employ a solid metal nickel-chrome alloy or manganese copper resistive element with large-area copper to realize  resistance values down to 100 µΩ and power ratings to 36W.

 
Compared with other manganese alloy shunts and Hall Effect current sensing solutions, MMS8518 increases accuracy and lower costs, and the two sense pins of the WSBS8518 aid in PCB mounting and provide consistent contact point locations on the shunt.
 
Offered in the 8518 case size, shunt MMS8518 features a proprietary processing technique that produces their extremely low resistance values, which allow for high current capabilities. The devices are designed for battery management in gas, diesel, hybrid, and electric cars and trucks, as well as electric forklifts, large UPS systems, and other heavy industrial applications.

 
Featuring an all-welded construction, the components offer low inductance values of < 5 nH, low thermal EMF down to < 1.25 µV/°C, and an operating temperature range of -65 °C to +170 °C. The resistors are RoHS-compliant, halogen-free, and Microhm Green. Samples and production quantities of the MMS8518 are available now, with a lead time of 3 to 4 weeks for larger orders.
