What are the key features of ERJT14J431U?
- Resistance: 430 Ω with ±5% tolerance for current-limiting and protection circuit applications
- Power rating: 0.5 W in a compact 1210 SMT package (3.2 mm × 2.5 mm × 0.6 mm)
- Temperature coefficient: ±200 ppm/°C for stable performance across wide temperature ranges
- RoHS compliant (Pb-free, JESD-609 code e3) for global environmental and regulatory compliance
- Rectangular thick film construction providing long-term reliability for industrial and commercial use
What is ERJT14J431U used for?
The ERJT14J431U is used in current-limiting circuits for power LEDs, protection resistors in motor drive interfaces, and load resistors in power supply test circuits where 430 Ω at 0.5 W is required. Its 1210 package provides greater power handling than 0805 or 1206 variants, making it suitable for applications dissipating up to 0.5 W continuously in industrial equipment and communication hardware. The surface-mount design supports high-volume automated PCB assembly.

Frequently Asked Questions
What current can the ERJT14J431U handle continuously, and what LED drive scenario does this support?
At 430 Ω and 0.5 W, the ERJT14J431U can carry up to approximately 34 mA continuously (I = √(P/R) = √(0.5/430) ≈ 34 mA). This supports single high-brightness LED current limiting from a 15 V rail with a typical 2 V forward voltage drop, dissipating 0.44 W — within the 0.5 W rating of the 1210 package.
How does the ERJT14J431U's 1210 package compare to 1206 for high-power resistor applications at 430 Ω?
The ERJT14J431U in a 1210 package (3.2 mm × 2.5 mm) handles 0.5 W, compared to 0.33 W for a typical 1206 resistor at the same 430 Ω value. In power supply feedback networks or relay coil drivers where dissipation exceeds 0.33 W, the 1210 package provides the necessary thermal margin. The wider 2.5 mm body also improves heat spreading on the PCB surface.
In which protection circuit topologies is the ERJT14J431U's 430 Ω resistance most effective?
The 430 Ω value of the ERJT14J431U is effective in series protection circuits for microcontroller GPIO pins, where it limits fault current to less than 12 mA at 5 V, preventing pin damage from accidental shorts. At 0.5 W, it also suits RS-485 bus termination circuits and optocoupler LED drive networks where the resistor must handle continuous current up to 30 mA at operating voltages of 12 V to 15 V.
Is the ERJT14J431U suitable for high-temperature industrial environments and what temperature range does it support?
The ERJT14J431U is RoHS compliant and manufactured to Panasonic's ERJT14 series industrial quality standards. Its ±200 ppm/°C temperature coefficient maintains resistance within ±2% over a 100°C span, and the package height of 0.6 mm ensures good thermal contact with the PCB. For applications requiring reliable 0.5 W performance at 85°C ambient or above, verify the derating curve in the ERJT14 series datasheet to ensure the 430 Ω resistor operates within safe thermal limits.
