The LRMAP3920 series high reliability, low value SMT shunt resistors perform current sensing duties in industrial and other heavy-duty apps. With values down to 200μΩ and a power rating of 5W on FR4 fibreglass circuit boards, the maximum measurable current is over 150A, and in most cases is restricted only by the current handling of the PCB tracks. An even higher 10W power rating may be achieved for assemblies on thermal substrates such as DBC (direct bonded copper) ceramic or IMS (insulated metal substrate), making these parts ideal for power hybrid modules. Aimed at designers of power supplies and motor drives in the industrial, automotive and medical industries, metal alloy resistors are ideal in the specific areas of regulating current flow, detecting stalled motors, and more importantly measuring power consumption.
