Applications
ERJ3BWFR062V is commonly used as a current-sense shunt resistor in battery management systems, motor drive current feedback loops, and DC-DC converter output current monitoring. Its 0.062 Ω value and 0.25 W rating minimize power loss in the measurement path while providing sufficient voltage drop for accurate ADC-based current sensing in designs operating at 1 A to 4 A.

Frequently Asked Questions
At 2 A load current, how much voltage does ERJ3BWFR062V develop across its terminals for ADC sensing?
With 0.062 Ω resistance and 2 A flowing, ERJ3BWFR062V develops 124 mV across its terminals (V = I × R = 2 A × 0.062 Ω). This 124 mV signal is within the typical input range of most 12-bit ADCs and current-sense amplifiers, enabling accurate load current measurement without an additional gain stage.
How does the anti-surge design of ERJ-BW series benefit a motor drive current-sense circuit?
Motor drives produce repetitive inrush and short-circuit current spikes that can exceed 10 A for several microseconds. The ERJ-BW anti-surge construction uses a wider resistive element geometry that absorbs surge energy without cracking the film. ERJ3BWFR062V is therefore more reliable under 5 A peak transient conditions than standard thick-film chip resistors of the same size.
For a battery management system needing ±1% current accuracy, how does ERJ3BWFR062V's tolerance compare to ±5% alternatives?
ERJ3BWFR062V carries ±1% (F grade) resistance tolerance, limiting initial measurement error to ±0.00062 Ω from the nominal 0.062 Ω. A ±5% alternative introduces ±0.0031 Ω error, which at 3 A translates to a 9.3 mV sensing inaccuracy versus 1.86 mV. For battery SOC calculations, the ±1% shunt reduces accumulated charge-counting error significantly over a full discharge cycle.
