For the development of current detection and shunting applications, Microhm Electronics's high current shunt MMS4320 adopts the welding structure of MuCu and NiCrAl precision resistance alloys.
 
The spacing standard design makes it easy for surface mounting, reflow soldering, and suitable for current sensing and shunting applications.
 
Open bare alloy element design allows air flow to achieve maximum cooling effect, so that PCB retains less heat. The design of flame protection structure provides 0.002Ω low resistance and low inductance. These factors make ruggedness  an excellent choice for all high current power supply and power applications that are not affected by most environmental stresses.
 Specially designed for applications requiring high power processing  The power is 2W, 4W and 7W. The ultra-low resistance ranges from 2mΩ to 10mΩ.
 
There are various tolerance selection advantages (±1%, ±2%, ±5%) , size 1503, 4312, and 4320. To achieve compact size and miniaturization, design a smaller, lower cost, higher performance, high power circuit terminal product design.
