What are the key features of ERJP14J1R1V?
- 1.1 Ω very low resistance in a 1210 SMT package with 0.5 W continuous power dissipation
- Asymmetric -100/+600 ppm/°C temperature coefficient suited for low-value current-sensing networks
- RoHS-compliant Pb-free Panasonic ERJP14 series with rectangular surface mount construction
- High-current compatible low-ohmic value enabling precision current measurement in power electronics
What is ERJP14J1R1V used for?
The ERJP14J1R1V is designed for current-sensing and current-limiting applications in DC-DC converters, battery management systems, and motor-drive circuits where a low 1.1 Ω value and 0.5 W power rating are required. The 1210 package provides adequate thermal dissipation for measuring currents up to several hundred milliamps without significant self-heating in compact SMT layouts.

Frequently Asked Questions
How is the ERJP14J1R1V used in current-sensing circuits within battery management systems?
At 1.1 Ω and 0.5 W, the ERJP14J1R1V placed in series with a battery cell or pack produces a voltage drop of 1.1 mV per milliamp of current, allowing a microcontroller ADC or dedicated fuel-gauge IC to measure charge and discharge currents typically ranging from 0 to 300 mA without exceeding the resistor's power rating.
What is the temperature stability of the ERJP14J1R1V over an industrial operating range?
The ERJP14J1R1V has an asymmetric -100/+600 ppm/°C temperature coefficient, meaning the 1.1 Ω value can drift up to 600 ppm per degree Celsius above ambient. Over a -40 °C to +85 °C industrial range of 125 °C, the resistance may shift up to 7.5%, which must be considered in precision current-sense designs.
When is the 1210 package of the ERJP14J1R1V preferred over a 0805 resistor at 1 Ω?
The 1210 case (3.2 mm × 2.5 mm body) supports 0.5 W continuous dissipation, which is double the 0.25 W limit of a typical 0805 resistor. For a 1.1 Ω current-sense application carrying 300 mA, the power dissipation is approximately 99 mW, comfortably within the 0.5 W rating but potentially exceeding 0805 limits under pulsed or elevated ambient conditions.
Is the ERJP14J1R1V compatible with lead-free reflow solder processes for RoHS designs?
Yes, the ERJP14J1R1V is Pb-free and JESD-609 e3 coded, making it fully compatible with SAC305 lead-free reflow solder profiles with peak temperatures up to 260 °C. Its REACH-compliant construction qualifies it for RoHS-restricted EU and global markets requiring 1.1 Ω low-value resistors in surface mount assemblies.
