Shunt resistors down to 0.3mΩ for automotive and industrial applications

January 25, 2018 // By Julien Happich
Rohm's PSR100 series ultra-low ohmic shunt resistors are based on a high-performance metal alloy as the resistive element, with superior temperature coefficients from ±50ppm to ±150ppm.

Thanks to the company's precision welding technology, they deliver a high rated power of 3W coupled with an ultra-compact form factor of 6.35x3.05mm. Their resistance range covers 0.3mΩ to 3.0mΩ. The resistance tolerance is specified with F (±1%), for an operating temperature range of -55 to +170°C. 
The PSR100 series is well suited to automotive and industrial applications as well as many other areas with high requirements in terms of performance and size. These include for example on-board chargers, electronic compressors and EPS in motor vehicles in addition to UPS and base stations.
