What are the key features of ERJT14J3R3U?
- 3.3 Ω low resistance enabling high-current sensing with minimal power loss
- 0.5 W power rating in a 1210 package for moderate current applications
- Temperature coefficient of -100 to +600 ppm/°C across wide operating conditions
- 3.2 mm × 2.6 mm 1210 footprint for automated SMD assembly
- Pb-free and REACH compliant with JESD-609 e3 code for green product compliance
- ±5% tolerance for general-purpose resistor network and filter circuit use
What is ERJT14J3R3U used for?
The ERJT14J3R3U is used in current sensing and limiting circuits in battery management systems and motor control boards, where the low 3.3 Ω resistance provides a measurable voltage drop without excessive power dissipation at moderate currents. Its 0.5 W rating and robust 1210 package are well suited for inrush current limiting in power supply input stages and soft-start circuits. Industrial automation designers also choose it for source degeneration resistors in linear amplifier and transistor bias networks operating at elevated temperatures.

Frequently Asked Questions
How does the ERJT14J3R3U perform as a current-sense resistor in a 1 A battery charging circuit?
At 1 A, the ERJT14J3R3U with 3.3 Ω resistance drops 3.3 V and dissipates 3.3 W, which exceeds its 0.5 W rating. It is better suited for sensing currents up to approximately 380 mA to stay within rated power, or used in parallel combinations for higher current sensing.
What is the impact of the -100 to +600 ppm/°C temperature coefficient on low-resistance circuit designs?
The asymmetric temperature coefficient of the ERJT14J3R3U means its 3.3 Ω resistance can increase by up to 600 ppm/°C at the positive extreme, resulting in a possible drift of up to 1.98 Ω over a 100 °C range. Designers should account for this asymmetric behavior in precision current-sensing circuits where resistance stability is critical.
When would a designer choose the 1210 ERJT14J3R3U over a similar 0805 resistor for inrush current limiting?
The 1210 package of the ERJT14J3R3U dissipates 0.5 W continuously, twice the 0.25 W of an 0805 resistor. This extra thermal headroom makes it the right choice when peak inrush currents cause brief power spikes in power supply input stages, reducing the risk of thermal stress and resistance drift over the product lifetime.
