Custom and Bulk Low-Ohmic Current Sensing Resistors for Automotive, BMS, Power Supply and Industrial Applications
From low-ohmic current monitoring to application-specific electrical matching, this product range covers multiple metal current sense resistor series for automotive, BMS, power supply, charging, and industrial projects. Different types can be selected according to resistance value, package structure, power rating, thermal behavior, and sourcing targets.
Metal Alloy Current Sense Resistors feature precision alloy strips for high accuracy, low resistance (0.2–500 mΩ), and stable performance under high loads. Their robust design ensures reliability in applications like battery management, automotive, DC-DC converters, and motor drives.
Slim Metal Alloy Current Sense Resistors feature a compact profile for space-limited PCBs. Despite their thin size, they offer precise current detection, low inductance, and high reliability. With resistance down to 1 mΩ, they suit portable devices, battery systems, and compact automotive modules needing precision and space efficiency.
Metal Alloy Shunt Resistors are designed for high-current measurement with resistance from 25 μΩ to 5 mΩ. Using electron beam welding of copper and alloy strips, they deliver excellent heat dissipation, low thermal EMF, and stable continuous performance. Common uses include BMS, energy storage, automotive powertrains, and industrial equipment requiring accuracy and durability.
Metal Foil Current Detection Resistors deliver ultra-high precision and extremely low temperature coefficient (TCR), making them suitable for demanding applications where accuracy and stability are essential. They are typically used in measurement equipment, medical devices, and precision power supplies.
Metal Film Current Sensing Resistors are high-precision resistors with a metal film on an insulating substrate, offering tight tolerance, low noise, and stable temperature performance. With resistance from 1 mΩ to 10 Ω, they provide reliable current sensing, accurate voltage monitoring, and consistent operation, combining durability, precision, and low drift for versatile current sensing applications.
