What are the key features of ERJT14J1R0U?
- 1 Ω resistance with ±5% tolerance for current sensing and inrush limiting circuits
- 0.5 W power dissipation rating in 1210 SMT package (3.2 mm x 2.6 mm x 0.6 mm)
- Temperature coefficient range of -100 to +600 ppm/°C for general-purpose stability
- Thick film rectangular construction enabling reliable high-volume SMT assembly
- RoHS and REACH compliant construction (JESD-609 Code e3, Pb-free)
- 12-year YTEOL for long-lifecycle support in industrial and consumer product lines
What is ERJT14J1R0U used for?
The Panasonic ERJT14J1R0U 1 Ω resistor is commonly used in low-side current sensing, inrush current limiting, and short-circuit protection circuits in DC-DC converters, motor drivers, and battery management systems. Its 0.5 W power rating in the 1210 SMT package provides additional thermal headroom compared to smaller case sizes, making it suitable for higher-current signal paths in power supply and automotive-grade electronics. The ±5% tolerance is appropriate for general-purpose current control and fault detection where precision shunt resistors are not required.

Frequently Asked Questions
How does the ERJT14J1R0U perform as a low-side current sense resistor in motor driver circuits?
The ERJT14J1R0U provides 1 Ω resistance at ±5% tolerance with a 0.5 W power rating, generating a measurable voltage drop proportional to motor current. At 500 mA load, it produces a 500 mV sense signal while dissipating 250 mW, well within its 0.5 W rated limit for reliable current monitoring in motor driver applications.
Why does the 1210 package of ERJT14J1R0U offer better thermal performance than 0805 or 1206 for 1 Ω applications?
The ERJT14J1R0U in the 1210 package (3.2 mm length, 2.6 mm width) offers 0.5 W continuous power dissipation, compared to 0.125 W in 0805 or 0.33 W in 1206. For a 1 Ω shunt resistor, this higher rating allows peak currents up to approximately 700 mA before exceeding the thermal limit, improving reliability in power circuits.
Is the ERJT14J1R0U a suitable choice for lead-free, environmentally regulated product lines?
Yes, the ERJT14J1R0U carries Pb-free (RoHS) and REACH Compliant status with JESD-609 Code e3, making it appropriate for consumer electronics, industrial equipment, and other products that must meet EU RoHS directives and global lead-free manufacturing requirements.
What is the expected factory lead time for ERJT14J1R0U, and how should procurement teams plan for this?
The ERJT14J1R0U has a 22-week factory lead time from Panasonic. Procurement teams designing long-lifecycle products should place stocking orders well in advance of production ramp, leveraging the 12-year YTEOL guarantee to support multi-year supply planning for industrial and consumer designs.
