What are the key features of ERJT14J2R2U?
- 2.2 Ω low resistance value ideal for current sensing and inrush current limiting in power circuits
- 0.5 W power rating in 1210 SMT package (3.2 mm x 0.6 mm) for substantial power dissipation
- -100 to +600 ppm/°C temperature coefficient for predictable low-ohm resistance over temperature
- RoHS and REACH compliant with JESD-609 e3 rating for lead-free PCB assembly
- Thick film rectangular construction in the Panasonic ERJT14 series for reliable SMT soldering
What is ERJT14J2R2U used for?
The Panasonic ERJT14J2R2U is designed for low-value current-sensing resistor positions, inrush current limiting networks, and source degeneration resistors in power amplifier and motor control circuits operating at 0.5 W. Its 2.2 Ω value in a 1210 package suits designs requiring a measurable voltage drop for overcurrent detection at currents up to approximately 475 mA before derating. The part is also used in LED driver circuits, soft-start networks, and protection circuitry where a compact SMT form factor is required.

Frequently Asked Questions
How does the ERJT14J2R2U's 2.2 Ω value support current sensing in power converter designs?
At 2.2 Ω and 0.5 W, the ERJT14J2R2U produces a measurable voltage drop of 220 mV at 100 mA, enabling accurate overcurrent detection in switch-mode power supplies and motor controllers without the need for precision shunt resistors in less critical sense paths.
What is the maximum safe continuous current through the ERJT14J2R2U at room temperature?
The ERJT14J2R2U is rated at 0.5 W with a 2.2 Ω resistance, yielding a maximum continuous current of approximately 477 mA at rated power, making it practical for current-limiting and inrush protection circuits in low-voltage power management and motor drive applications within the 1210 footprint.
How does the -100 to +600 ppm/°C temperature coefficient affect accuracy in current sensing applications?
A -100 to +600 ppm/°C TCR on a 2.2 Ω resistor introduces up to ±1.32 mΩ per degree Celsius drift, which is acceptable for general current-limiting and protection circuits but warrants verification in precision current sensing applications where resistance accuracy over the full -55 °C to +155 °C range is critical.
Can the ERJT14J2R2U be ordered in tape-and-reel for automated SMT assembly production?
Yes, the ERJT14J2R2U is a standard Panasonic ERJT14 series 1210 thick film resistor available in tape-and-reel packaging for automated SMT pick-and-place assembly. It carries RoHS Pb-free certification and a JESD-609 e3 code, supporting lead-free reflow soldering in high-volume production environments with a 22-week factory lead time.
