What are the key features of ERJP14J1R0U?
- 1 Ω low resistance value in a 1210 package (3.2 mm × 2.5 mm) ideal for current-sensing and power-path circuits
- 0.5 W continuous power rating handles higher current loads than standard 0805 resistors of the same resistance
- -100 to +600 ppm/°C temperature coefficient provides predictable drift performance across a broad operating temperature range
- RoHS-compliant lead-free construction (JESD-609 e3) and REACH Compliant for global regulatory compliance
What is ERJP14J1R0U used for?
The ERJP14J1R0U suits current-sensing shunt resistor applications in battery management systems, motor driver boards, and power monitoring circuits where 1 Ω at 0.5 W provides a measurable voltage drop for sensing without excessive power loss. Its 1210 package handles higher power dissipation than smaller SMD footprints, making it appropriate for DC-DC converter feedback networks and power-distribution PCBs. The REACH and RoHS-compliant construction ensures suitability for global consumer electronics and industrial applications.

Frequently Asked Questions
How much current can the ERJP14J1R0U carry continuously without exceeding its power rating?
At 1 Ω and 0.5 W maximum power rating, the ERJP14J1R0U can carry a continuous current of approximately 707 mA (I = √(P/R) = √(0.5/1)). In practice a 20% derating to 0.4 W is recommended, limiting the safe continuous current to about 632 mA. This makes it appropriate for current-sense and power-path circuits in the 0.5 A to 0.7 A range.
Why choose the 1210 package of the ERJP14J1R0U over a smaller 0805 package for a 1 Ω resistor in a power supply design?
The 1210 package (3.2 mm × 2.5 mm) provides double the power rating—0.5 W versus 0.25 W for an 0805 resistor—because its larger PCB footprint dissipates heat more effectively. For a 1 Ω current-sense application passing 600 mA, the 1210 dissipates 360 mW, well within its 0.5 W limit, whereas an 0805 version would operate dangerously near its 0.25 W ceiling.
What does the asymmetric -100 to +600 ppm/°C temperature coefficient mean for voltage readings in a battery current-sense circuit?
An asymmetric temperature coefficient of -100 to +600 ppm/°C means the 1 Ω resistance can drift up to 0.06% per °C in the positive direction over temperature. Across a 50°C operating window this could shift the apparent sense voltage by up to 3%, so for precision current measurement a calibration step or a temperature-compensated amplifier stage should be added to maintain accuracy better than ±3% in battery management system designs.
Is the ERJP14J1R0U lead-free and compliant with EU REACH regulations for use in exported electronic assemblies?
Yes. The ERJP14J1R0U carries the Panasonic Pb-free code 'Yes' and a JESD-609 code of e3, confirming lead-free terminations. Panasonic also lists it as REACH Compliant, meaning it contains no substances of very high concern above permitted thresholds. Both qualifications are required for electronic assemblies sold in the European Union under the RoHS Directive and REACH Regulation.
