Frequently Asked Questions
What resistance value and tolerance does the ERJM1WSF5M0U offer?
The ERJM1WSF5M0U is a 5mΩ (0.005Ω) current-sense shunt with high-precision ±1% tolerance and a ±100ppm/°C temperature coefficient rated for -55°C to +155°C operation.
Why is the wide-terminal ERJM1WSF5M0U preferred for high-current sensing?
Its wide-terminal construction lowers thermal resistance so the 5m�ered shunt dissipates heat efficiently, while the ±1% precision delivers accurate readings at high current with only millivolts of drop.
What package dimensions does the ERJM1WSF5M0U use?
It uses a wide-terminal rectangular case measuring 6.4mm in length with a 0.8mm height, a surface-mount footprint optimized for heat dissipation in high-current shunt applications.
How does the ERJM1WSF5M0U compare to a standard 2512 shunt resistor?
The wide-terminal ERJM1WSF5M0U spreads heat better than a standard 2512 part, so its 5mΩ ±1% element handles higher current with lower temperature rise across the -55°C to +155°C range.
