What are the key features of ERJP14J4R3V?
- 4.3 Ω resistance in 1210 SMD package (3.2 mm × 2.5 mm) offering 0.5 W power dissipation
- ±5% tolerance suitable for general-purpose load, biasing, and protection resistor applications
- -100 to +600 ppm/°C TCR provides adequate thermal stability for commercial-grade designs
- Pb-free JESD-609 e3 RoHS-compliant construction for international regulatory compliance
What is ERJP14J4R3V used for?
The ERJP14J4R3V is designed for current limiting, pull-down biasing, and resistive load applications in consumer electronics and industrial control systems operating at up to 0.5 W. The 4.3 Ω resistance value suits motor speed control snubber networks, LED driver protection circuits, and relay coil discharge paths where low resistance is needed with moderate power handling. Its 1210 SMD format enables high-density automated board assembly with standard reflow soldering.

Frequently Asked Questions
How does the 0.5 W power rating of ERJP14J4R3V compare to ERJP08J4R3V for the same 4.3 Ω resistance?
The ERJP14J4R3V in the 1210 package (3.2 mm × 2.5 mm) is rated at 0.5 W, which is slightly lower than the ERJP08J4R3V in 1206 package at 0.66 W, both sharing the same 4.3 Ω resistance value. The 1210 package is physically wider but optimized differently by Panasonic for this series. For higher current applications requiring maximum thermal headroom at 4.3 Ω, the ERJP08 variant at 0.66 W is preferable.
What steady-state current can flow through ERJP14J4R3V without exceeding its 0.5 W power limit?
The ERJP14J4R3V can sustain a continuous current of approximately 341 mA before reaching its 0.5 W power limit (calculated as √(0.5 W / 4.3 Ω) ≈ 0.341 A). This makes it appropriate for medium-current circuit protection in 5 V or 12 V DC systems, such as fuse resistors in battery management boards, motor current sensing, and indicator LED current control where moderate currents flow.
In what temperature range does ERJP14J4R3V maintain acceptable resistance stability for industrial designs?
With a -100 to +600 ppm/°C TCR, the ERJP14J4R3V maintains adequate resistance stability across the -55 °C to +155 °C range typical of industrial applications. Over a 100 °C temperature swing, the worst-case resistance shift is about 0.26 Ω on the 4.3 Ω nominal, equating to roughly 6% drift. For circuits tolerant of ±5% part variation this is acceptable, and the Panasonic ERJP14 series is commonly used in industrial control panels, motor drives, and energy metering equipment.
