Frequently Asked Questions
What is the resistance value and tolerance specification of the Panasonic ERX-3SJR47?
The ERX-3SJR47 has a nominal resistance of 0.47 Ω with ±5% tolerance, resulting in a range of 0.4465 Ω to 0.4935 Ω. This precision tolerance is ideal for current-sensing shunt resistors in battery chargers, power supplies, and DC motor controllers where accurate current measurement within ±5% is required for system protection and monitoring.
How does the 0.47 Ω metal-film resistor perform in high-current sensing circuits?
The ERX-3SJR47 is designed for high-current sensing applications where shunt resistor voltage drop needs to remain low to preserve power efficiency. At 10 A current, this 0.47 Ω resistor generates 4.7 V sense voltage with approximately 47 W power dissipation. The metal-film construction maintains stable resistance from -55°C to +155°C, ensuring consistent current monitoring accuracy across temperature extremes.
What package type and mechanical mounting features does the ERX-3SJR47 provide?
The ERX-3SJR47 utilizes a traditional axial through-hole package with wire leads for direct PCB mounting and soldering. This configuration enables robust mechanical connection suitable for high-vibration industrial environments and high-current power applications where traditional leaded component reliability is preferred over surface-mount alternatives.
In which power supply and motor control applications is the ERX-3SJR47 commonly used?
This 0.47 Ω resistor is widely employed in battery charging circuits, DC-DC converter current limiting, motor controller shunt paths, and power distribution protection schemes requiring 5-10 A current monitoring. Its low impedance and stable metal-film characteristics support accurate current sensing in industrial equipment and renewable energy applications operating at 12 V, 24 V, or 48 V rails.
