Frequently Asked Questions
How accurate is the ERJ8RQFR82V for current sensing in battery management circuits?
The ERJ8RQFR82V provides 820 mΩ with ±1% tolerance, meaning the actual resistance stays within 811.8 mΩ to 828.2 mΩ. At 1 A load current, this produces a sense voltage of approximately 820 mV with no more than 8.2 mV error, giving better than 1% current measurement accuracy before amplifier offset is considered—suitable for precision battery fuel gauge circuits.
What is the maximum continuous current the ERJ8RQFR82V can carry at full power rating?
At 820 mΩ and 0.25 W power rating, the ERJ8RQFR82V supports a maximum continuous current of approximately 552 mA. For most 5 V battery-powered designs where load currents range from 100 mA to 500 mA, this component operates comfortably within its thermal limits without requiring derating.
Why is the ±250 ppm/°C TCR specification important for the ERJ8RQFR82V in temperature-varying environments?
The ±250 ppm/°C TCR of the ERJ8RQFR82V means resistance shifts by up to 0.025% per degree Celsius. Over a 100°C operating range from -40°C to +85°C, the total drift reaches ±2.5%, which adds to the initial ±1% tolerance. Designers should account for this combined drift when targeting current-sensing accuracy below 5% in automotive or industrial applications.
Can the ERJ8RQFR82V replace a wirewound shunt resistor in a 1 A DC motor current-sense circuit?
The ERJ8RQFR82V can replace wirewound shunts in many 1 A motor current-sense circuits, offering the advantages of an SMD footprint (3.2 mm × 1.6 mm), automated assembly compatibility, and lower inductance than wirewound types. However, its 0.25 W rating limits continuous current to 552 mA; for 1 A applications, dissipation would reach 820 mW, exceeding the rating, so derating or an alternative higher-power component is required.
