Metal Current Sense Resistors

PROSEMI is the only mainland Chinese brand that designs, develops, and manufactures full-size precision alloy resistors with micro resistance values (0402~1206~2512~5930) for surface-mount applications. The products meet AEC-Q200 automotive-grade certification and have a resistance value up to 500 milliohms, making them suitable for power industry requirements. They also meet the demand for low temperature coefficient (≤25ppm) in end applications, low inductance (<5nH) requirements in the air conditioning industry, and application needs in the new energy sector, including motor drives, charging stations, and energy storage.

Overcurrent Protection Device

Overcurrent fuses are protective components designed to interrupt excessive current and safeguard electronic systems from overheating, short-circuit damage, and electrical faults. Featuring precise melting characteristics, fast response times, and stable performance across wide temperature ranges, these fuses deliver reliable protection in applications such as power supplies, automotive electronics, battery systems, consumer devices, and industrial control equipment. By breaking the circuit when current exceeds the rated threshold, overcurrent fuses prevent component failure and ensure long-term system safety. Browse the categories below to find the right fuse series for your required current rating, voltage rating, and application environment.
