TT Electronics has extended the value range of the high power current shunt LRMAP3920. The range is now 200μΩ to 3mΩ.
LRMAP3920 uses bulk metal technology with e-beam welded copper terminations to deliver very low surface temperatures and excellent surge energy performance. Typical load life stability of ±0.5%, together with TCRs down to ±50ppm/°C and thermal EMFs <2µV/°C, result in only a small part of the designer’s error budget being consumed, enabling more design freedom elsewhere in the circuit.
This AEC-Q200 qualified product is ideal for the design of current sense functions in PSU, battery management and motor control applications.
