Key Features

2512 Package Size: 6.4mm * 3.2mm dimensions enable efficient heat dissipation for the 7W power rating
0.001Ω (1m Ohm): Ultra-low resistance minimizes voltage drop for accurate current measurement
7W Power Rating: Suitable for high-current paths in power supplies, motor drives, and battery systems
1% Tolerance: Ensures consistent and accurate current measurement across all units

Critical Role of Ultra-Low ESRH (1m Ohm)

The 0.001Ω (1m Ohm) ESR minimizes power loss (P = I²R) and reduces heat generation with high currents. This efficiency makes it ideal for maximizing battery life in electric vehicles and improving power conversion systems.

Superior Material and Construction

Manganese-Copper (KARMA) alloy provides:

Low Temperature Coefficient of Resistance (TCR) for stable performance across temperature ranges
Excellent long-term stability against oxidation and degradation
Minimal thermoelectric EMF when connected to copper PCB traces
Enhanced Performance Features
Low Inductance Design: Optimized for high-frequency applications without signal distortion
High Surge Current Capability: Withstands transient overloads for rugged system performance

Application Areas

Automotive Electronics: EV battery packs, motor controllers, onboard chargers
Industrial Automation: PLC I/O modules, servo drives, power inverters
Telecommunications & Server Power Supplies: High-efficiency converters
Solar Inverters and Energy Storage Systems: Charge/discharge monitoring
Conclusion

The 2512 0.001Ω (1m Ohm) 12W metal shunt chip resistor combines ultra-low resistance with robust power dissipation, 1% tolerance, and exceptional stability. Its low inductance and high surge resilience make it ideal for demanding current sensing applications in automotive, industrial, and renewable energy sectors.
