What are the key features of ERJT08J1R0V?
- 1 Ω ultra-low resistance for precision current-sensing and shunt applications
- 0.33 W power rating in 1206 case enabling higher current handling than 0805 alternatives
- ±5% tolerance with -100 to +600 ppm/°C TCR for repeatable performance across temperature
- Thick-film rectangular SMT construction supporting automated reflow soldering
- RoHS-compliant (JESD-609 e3) meeting global environmental requirements
- 1206 footprint providing larger pad area for lower thermal resistance to PCB
What is ERJT08J1R0V used for?
The ERJT08J1R0V is primarily used as a current-sense shunt in battery charging circuits, motor driver stages, and DC-DC converters, where its 1 Ω low resistance produces a measurable voltage drop proportional to the current flowing through it while keeping power losses below 0.33 W. It also serves as a series termination or inrush-limiting resistor in power-distribution paths and LED driver modules, benefiting from the 1206 package's larger footprint for improved heat spreading on the PCB.

Frequently Asked Questions
How does a 1 Ω shunt resistor like the ERJT08J1R0V simplify current measurement in a 300 mA circuit?
With 1 Ω and 300 mA flowing, the ERJT08J1R0V develops 300 mV across its terminals, which a standard op-amp comparator or microcontroller ADC can measure directly without additional gain stages. The 90 mW of power dissipated at that load is well below the 0.33 W rating, ensuring safe continuous operation without derating.
For motor-driver inrush limiting, what peak current can the ERJT08J1R0V handle without exceeding its power rating?
The ERJT08J1R0V is rated for 0.33 W continuous, which at 1 Ω corresponds to approximately 575 mA of continuous RMS current. Brief inrush pulses above this level are tolerable within the thick-film component's thermal mass, but sustained currents exceeding 575 mA risk overheating the 1206 resistor and should be managed with appropriate duty-cycle derating.
What procurement lead time applies to the ERJT08J1R0V and how should buyers plan for volume orders?
Panasonic specifies a 22-week factory lead time for the ERJT08J1R0V. Volume buyers integrating this 1 Ω 1206 current-sense resistor into motor-driver or power-management products should submit blanket purchase orders at least 5-6 months before production start dates or pre-qualify alternative stocking distributors to avoid supply-chain gaps during high-demand periods.
