What are the key features of ERJP03J3R6V?
- Ultra-low 3.6 Ω resistance enables precise current sensing without significant voltage drop in power distribution
- 0.2 W rating with excellent current handling up to 235 mA allows compact sensor shunt applications
- 0603 form factor fits dense PCB layouts while maintaining thermal capability for continuous power monitoring
What is ERJP03J3R6V used for?
The ERJP03J3R6V is widely used as a current-sense resistor in battery charging circuits, power supply monitoring, and DC motor current limiting where precise 3.6 Ω impedance measurement is essential. Its 0.2 W rating handles continuous current sense applications in 5 V and 12 V power rails for IoT power management, industrial DC loads, and automotive auxiliary power distribution. The ultra-low resistance minimizes wasted power and thermal dissipation while enabling accurate analog-to-digital converter (ADC) measurement of load currents.

Frequently Asked Questions
What voltage drop occurs across the ERJP03J3R6V when 100 mA current flows through it?
At 100 mA current, the ERJP03J3R6V produces a voltage drop of 360 mV (0.36 V), calculated from Ohm's law: V = I × R = 0.1 A × 3.6 Ω. This 360 mV signal is ideal for amplification and ADC measurement in current-sense circuits using op-amp transimpedance topologies. The ±5% tolerance means actual voltage drop will range from 342 mV to 378 mV at 100 mA, providing repeatable measurement accuracy suitable for battery management systems, industrial motor controllers, and power supply telemetry applications monitoring 5-12 V rails.
How much current can the ERJP03J3R6V safely handle at its 0.2 W power dissipation limit?
The ERJP03J3R6V is rated for 0.2 W continuous power, which translates to approximately 235 mA maximum continuous current through the 3.6 Ω resistor (I = √(P/R) = √(0.2/3.6) = 0.235 A). At this 235 mA limit, the resistor dissipates full 0.2 W as heat without thermal runaway. For practical current sensing, designers typically operate at 50-80% of this maximum, limiting 100-150 mA continuous sensing currents to keep thermal dissipation under 0.1 W. The 0603 package effectively dissipates this heat without external heatsinks in typical PCB mounting conditions.
Is the ERJP03J3R6V suitable as a battery pack discharge current-sense resistor for portable power supplies?
Yes, the ERJP03J3R6V is excellent for battery discharge current sensing in portable chargers and power banks. When connected in series with battery discharge paths, its 3.6 Ω resistance with ±5% tolerance allows accurate measurement of 1-5 A discharge currents via 3.6-18 V voltage drops, which are easily digitized by 12-16 bit ADCs. The 0.2 W rating handles continuous 2-3 A battery discharge without thermal issues, while the wide -150 to +400 ppm/°C temperature coefficient allows firmware compensation for temperature-induced resistance drift during high-current discharge cycles in mobile devices and power tools.
What is the power dissipation when the ERJP03J3R6V is used as a 3.6 Ω sense resistor at 50 mA load current?
At 50 mA load current through the 3.6 Ω resistor, power dissipation is 9 mW (P = I² × R = (0.05)² × 3.6 = 0.009 W), well below the 0.2 W maximum rating. This 9 mW represents only 5% of the resistor's power budget, leaving 95% thermal margin for temperature cycling, fault conditions, and aging effects. The minimal 180 mV voltage drop (50 mA × 3.6 Ω) is perfect for sensitive battery management systems requiring sub-200 mV signal levels for ADC capture. The 0603 form factor efficiently dissipates even this low 9 mW through the small PCB mounting area.
