About

About Susumu Susumu is a Japan‑based resistor manufacturer established in 1964.We provide shunt resistors with extremely low resistance values, tight tolerances, and excellent pulse‑current robustness. These features ensure highly accurate current measurement even under harsh automotive conditions, enabling safer and more efficient systems.We also supply thin film resistors that deliver high accuracy and outstanding reliability for advanced electronics. Their exceptional temperature stability and long‑term drift performance make them ideal for EV control units, BMS, inverters, onboard chargers.With decades of expertise and a strong track record with leading EV and energy‑storage manufacturers, Susumu provides components that help engineers push the boundaries of performance, efficiency, and miniaturization.
