What are the key features of ERJT08J1R3V?
- Ultra-low 1.3Ω resistance with ±5% tolerance in standard 1206 SMD package
- 0.33W rated power dissipation for current sensing and protection circuit roles
- -100 to +600 ppm/°C temperature coefficient for stable low-resistance performance
- REACH compliant (JESD-609 e3) construction for global regulatory compatibility
- Compact 3.2mm x 1.6mm x 0.6mm SMT profile for dense PCB layout designs
- Thick film rectangular construction provides repeatable, cost-effective low-ohm values
What is ERJT08J1R3V used for?
The ERJT08J1R3V is well-suited for current sensing, inrush current limiting, and fuse-resistor protection in power supply and battery management circuits. Its 1.3Ω low resistance value minimizes voltage drop in power paths while still providing measurable current sensing signal at typical operating currents. The 1206 SMD package and 0.33W power rating accommodate moderate current levels in embedded power management, motor driver bypass, and overcurrent detection designs.

Frequently Asked Questions
What are the electrical characteristics of the ERJT08J1R3V low-resistance resistor?
The ERJT08J1R3V provides 1.3Ω resistance with ±5% tolerance and 0.33W power dissipation. Its temperature coefficient spans -100 to +600 ppm/°C, and it is housed in a 1206 SMD package (3.2mm x 1.6mm x 0.6mm), making it suitable for low-ohm sensing applications in surface mount assemblies.
What maximum continuous current can the ERJT08J1R3V handle in a current sensing application?
At a 0.33W maximum power rating and 1.3Ω resistance, the ERJT08J1R3V can carry approximately 504mA continuous current (from I = sqrt(P/R)). This makes it practical for current sensing in battery chargers, DC-DC converters, and motor control stages where sensing accuracy at sub-ampere levels is required without excessive power loss.
How does the -100 to +600 ppm/°C temperature coefficient affect current sensing accuracy across temperature?
The asymmetric -100 to +600 ppm/°C temperature coefficient means the 1.3Ω resistance of the ERJT08J1R3V can rise noticeably at elevated temperatures, shifting by as much as +6% over a 100°C span at maximum TCR. For high-accuracy current sensing, this drift must be accounted for in firmware calibration or by selecting a tighter TCR variant, especially in applications operating above 85°C.
When would a designer choose the 1206 ERJT08J1R3V over a dedicated current sense shunt resistor?
The ERJT08J1R3V is cost-effective for low-precision current sensing where ±5% resistance tolerance and wider TCR are acceptable, such as overcurrent threshold detection or coarse current monitoring in 12V or 24V power subsystems. Dedicated shunt resistors offer tighter tolerances (±0.5% or better) and lower TCR but at higher cost, making the ERJT08J1R3V the pragmatic choice in cost-sensitive designs with relaxed accuracy requirements.
