Microhm Electronics, a global provider of passive components, announced E-Beam Welded Shunt­ resistors for industrial and automotive applications. MMS8420 is an electron beam welded resistance element, sandwiched between large copper terminals with optional tin plating. Precision applications can make use of its 1% tolerance, 100ppm/°C TCR, 1µV/°C thermal EMF and separate ground pins to reduce errors.
 
The low measurement error of this resistor enable designer's cost down and its low ohmic values reduces power loss. The MMS8420 provides the wide range of values ranging from 50µΩ to 2000µΩ.

 
MMS8420 features low self-heating which reduces equipment temperature and improves reliability for designers needing to manage temperature rise in compact power electronic assemblies.­­­The robust electron beam welded technology and low thermal EMF of this resistor make it advantageous for HEV battery management, energy metering and welding power supplies.
Microhm Electronics’ MMS8420 can replace similar products from key competitors. This includes the slightly different 8518 format.It can be made to 8518 size.
