Microhm Electronics power metal strip resistors, offered in an 8518 case size and an all-welded construction. It is manufactured with a solid metal nickel-chrome alloy resistive element with a calibration notch and “boot” design on their terminals. This improves TCR performance for better accuracy over temperature extremes.


It offers very low resistance down to 100 microohms thanks to a proprietary technique and power ratings up to 36 W. The resistors feature a proprietary processing technique that produces their extremely low resistance values, which allow for high current capabilities. It offers 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 and halogen-free.

MMS8518 is a shunt resistor  for tough environmental conditions. Applications include battery management in gas, diesel, hybrid, and electric cars and trucks, as well as electric forklifts, large UPS systems, and other heavy industrial applications.



Fixed resistor manufacturers face continued demand for extended operating temperature ranges and AEC-Q200 qualified parts for automotive and industrial applications that need high stability in harsh environments. At the same time, a continuing trend towards miniaturization poses an additional challenge as manufacturers try to pack more performance in smaller package sizes. Microhm Electronics foucses on the resistors delivering high reliability, high stability, or high temperature performance for a range of applications that require more robust performance.
