Shunt resistors are manufactured by using the technique of high-energy electron beam welding. With the large-area Cu terminal and high density CuMnNi, CuMnSn, NiCrAlSi or FeCrAl, the resistance value of less than 100μΩ,high current density and high pulse power are realized by using metal strips. The CuMnNi, CuMnSn, NiCrAlSi and FeCrAl  materials can be punched into various shapes, offering the flexibility in design of resistors with the desired structure.


 
Due to all these features, shunt resistor is being an indispensible part of automotives. Microhm's MMS2725, MMS3920 and MMS4206 is used in EPS, MMS3920 is applied to climate control system converter. MMS2725 and MMS2512 is suitable for DC/DC converter and MMS8420 is very popular for battery management system and power electronics control.
 
Complete ideal resistors preventing from external interference is not exist in reality, while Microhm spare no efforts to minimize the external disturbance.
