Bare alloy resistor (also known as bare pure alloy current-sensing/shunt resistor) is a high-power milliohm-level resistor without resin/plastic encapsulation coating, with its alloy resistive element directly exposed. It is specially designed for high-current precision current sensing.
Power rating: Starts from 5 W, some models 10–15 W;
Operating temperature: -55℃ to 170℃, compliant with AEC‑Q200.
Key Advantages & Precautions
Excellent heat dissipation: Large exposed surface area enables fast heat release and higher power density.
Ultra‑stable resistance: Low temperature coefficient, low thermal EMF, high surge current capability; suitable for harsh working conditions.
Soldering restrictions: Generally only compatible with reflow soldering; avoid high-temperature damage from wave soldering. Anti‑oxidation and mechanical protection required. Not suitable for unprotected dusty or humid environments.
Typical Applications
Current sensing and shunting in new energy vehicle BMS, industrial power supplies, frequency converters, servo drives, photovoltaic inverters, and charging piles.
Selection & Purchasing Tips
Select package and power rating based on maximum current, power dissipation, and PCB space. Prioritize low TCR, low inductance, and Kelvin 4‑terminal design.
Soldering process must match reflow soldering. Apply coating or housing for protection if necessary.
