Wherever currents are measured, shunts are used. Two new models from Japanese specialist Susumu open up new possibilities in demanding application areas.

The current sensing resistors of the MSRPF2726 and MSRPF4026 series are designed for high accuracy and reliable results. With their tight tolerance of up to ±0.5%, they consistently ensure precise measurements. Manufactured using high-precision electron beam welding and innovative resistor alloys, they eliminate the need for fine-tuning by trimming. As a result, these resistors are also free from undesired side effects such as thermal hotspots and limitations in current carrying capacity. The materials used provide high temperature stability: for versions with resistance values between 3 mΩ and 5 mΩ, the temperature coefficient (TCR) is a maximum of ±75 ppm, and for versions from 1 mΩ to 2 mΩ, it is only ±50 ppm. The shunts are equipped with four terminals—two each for current connection and measurement tapping. The difference between the MSRPF2726 and MSRPF4026 versions lies in the design of these pins.

The shunts of the MSRPF2726 and MSRPF4026 series meet the requirements of the automotive standard AEC-Q200. This makes them ideal for use in electromobility—whether in battery management systems (BMS), inverters for drive motors, or DC/DC converters. Other worthwhile target applications can be found in instrumentation, medical technology, and precision power supplies. (mr)
