What are the key features of ERJP14J102U?
- 1 kΩ thick film resistor with ±5% tolerance ideal for pull-up, pull-down, and current-limiting circuits
- 0.5W power handling in the 1210 SMD package (3.2 mm × 1.6 mm) with only 0.6 mm height for space-constrained PCBs
- ±200 ppm/°C temperature coefficient with ≤155°C max operating temperature for broad industrial and consumer use
What is ERJP14J102U used for?
The ERJP14J102U 1 kOhm resistor is widely used as a pull-up or pull-down resistor on digital signal lines in microcontroller-based designs, UART, I2C, and SPI bus networks. Its 0.5W power rating in the compact 1210 package also makes it suitable for base current-limiting resistors in bipolar transistor switching stages and LED indicator circuits. The RoHS-compliant, lead-free construction supports automated SMT reflow assembly in consumer electronics, telecom equipment, and industrial automation systems.

Frequently Asked Questions
What voltage can be applied across the ERJP14J102U without exceeding its 0.5W rating?
The maximum continuous voltage across the 1 kOhm ERJP14J102U at 0.5W is V = sqrt(P × R) = sqrt(0.5 × 1000) ≈ 22.4 V. The component also carries a rated working voltage; always verify the lower of the calculated voltage and the specified maximum working voltage in the Panasonic ERJP14 datasheet before deploying in circuits above 50 V.
How does the ERJP14J102U (1210 package) fit a board design originally using 0603 pull-up resistors?
The 1210 package occupies a 3.2 mm × 1.6 mm footprint and stands 0.6 mm tall, significantly larger than the 0603 package at 1.6 mm × 0.8 mm. A PCB redesign with updated land patterns and component placement is required. The tradeoff is a 0.5W power rating versus the typical 0.1W for 0603 resistors, which is beneficial when the pull-up line carries higher currents or the design needs robustness against transients.
For 3.3 V I2C bus pull-up, how many ERJP14J102U resistors should be used per line?
A single 1 kOhm ERJP14J102U per I2C line (SDA and SCL) is typically sufficient for 3.3 V fast-mode I2C running at 400 kHz with bus capacitance below 400 pF. The resulting pull-up current is 3.3 V / 1 kOhm = 3.3 mA, well within the 0.5W (22.4 V maximum) rating. For longer PCB traces or multiple devices adding more than 400 pF total capacitance, a lower resistance or active pull-up may be needed.
