What are the key features of ERJP08J3R3V?
- 3.3 Ω low-resistance value with ±5% tolerance for current sensing and bypass applications in power circuits
- 0.66 W power rating in 1206 package (3.2 mm × 1.6 mm) enabling robust heat dissipation in high-current signal paths
- -100 to +600 ppm/°C temperature coefficient providing predictable resistance behavior across wide temperature excursions
- RoHS compliant with JESD-609 e3 halogen-free designation for environmentally regulated markets
- Thick film rectangular construction with surface mount 0.6 mm height for automated pick-and-place PCB assembly
What is ERJP08J3R3V used for?
The ERJP08J3R3V is suited for current-limiting, inrush current protection, and low-value bypass resistor applications in power conversion circuits, motor driver boards, and LED driver modules operating up to several amps. Its 3.3 Ω value at 0.66 W allows operation at up to approximately 450 mA continuous current before exceeding the rated power. The component also serves in snubber networks and soft-start circuits where a small series resistance damps switching transients across a broad temperature range.

Frequently Asked Questions
How much continuous current can the ERJP08J3R3V safely handle at its rated power?
At 3.3 Ω and 0.66 W rating, the ERJP08J3R3V safely handles up to approximately 447 mA continuous current (derived from I = sqrt(P/R) = sqrt(0.66/3.3)). In motor driver or LED driver circuits where current peaks briefly exceed this, designers should derate to around 70% of rated power, limiting continuous current to roughly 315 mA for reliable long-term operation.
What does the asymmetric -100 to +600 ppm/°C temperature coefficient mean for circuit design?
The asymmetric -100 to +600 ppm/°C range means the 3.3 Ω ERJP08J3R3V resistance can increase by up to 600 ppm per degree above 25°C, reaching as much as 5.3 Ω at 155°C in the worst case. Engineers using this part in precision current sensing must account for this upward drift, while the -100 ppm/°C downward limit at cold temperatures keeps resistance close to nominal down to -55°C.
When would a designer choose the 1206 ERJP08J3R3V over an 0805 3.3 Ω resistor?
The 1206 package at 3.2 mm × 1.6 mm provides 0.66 W rated power, roughly 65% more than a typical 0805 0.4 W resistor. For a 3.3 Ω sense resistor in a 300 mA to 400 mA path, the 1206 stays well within its thermal limit whereas an 0805 would be operating near its derating threshold. The 1206 is preferred whenever operating conditions push power dissipation above 0.4 W consistently.
Is the ERJP08J3R3V suitable for use as a current sensing resistor in a 5 V motor driver circuit?
Yes, the ERJP08J3R3V works as a current sensing resistor in 5 V motor drivers drawing up to 400 mA. At 3.3 Ω and 400 mA, it develops a 1.32 V sense voltage — well within the ADC input range of most microcontrollers — while dissipating 0.528 W, safely below the 0.66 W rating. However, for 12 V systems drawing higher currents, a lower resistance sense resistor (0.1 Ω to 0.5 Ω) is typically preferred to reduce power loss.
