What are the key features of ERJP08J1R3V?
- 1.3Ω low-resistance thick film resistor with 0.66W power rating for current sensing and snubber circuit applications
- 1206 SMT package with 3.2mm body length and 0.6mm height for standard automated surface mount assembly
- RoHS and REACH compliant lead-free construction with -100 to +600ppm/°C temperature coefficient for general-purpose designs
What is ERJP08J1R3V used for?
The ERJP08J1R3V is well suited for current sensing resistors in motor driver circuits, inrush current limiters, and snubber networks in switching power supplies. Its low 1.3Ω resistance and 0.66W power handling allow accurate current measurement at ampere-level loads without excessive voltage drop in the sensing path. This surface mount resistor is commonly used in battery management systems, DC-DC converters, and load protection circuits in consumer and industrial electronics.

Frequently Asked Questions
What current can the ERJP08J1R3V handle while staying within its 0.66W power rating?
At the 0.66W power limit, the ERJP08J1R3V can continuously pass approximately 713mA through its 1.3Ω resistance, since power equals current squared times resistance. In practical current sensing applications on 5V or 12V rails, this resistor develops a sensing voltage of approximately 0.93V at 713mA, making it suitable for current monitoring circuits in motor control and power management designs.
How does the 1.3Ω value of ERJP08J1R3V make it useful for inrush current limiting in power supply designs?
The 1.3Ω resistance of ERJP08J1R3V limits inrush current peaks when placed in series with bulk capacitors or at the power input of switching converters. For a 12V supply with 1000µF capacitor, the 1.3Ω resistor limits peak inrush current to approximately 9.2A while developing a 1V drop at that peak, providing meaningful surge protection without excessive steady-state losses at typical operating currents of 100mA to 500mA.
How does the -100 to +600ppm/°C temperature coefficient of ERJP08J1R3V affect accuracy in current sensing over temperature?
The asymmetric -100 to +600ppm/°C temperature coefficient means the 1.3Ω resistance can drift up to 0.078Ω at an elevated 100°C temperature rise in worst-case conditions, introducing a 6% error in current sensing measurements. For precision current monitoring, this drift should be accounted for in system calibration; if tighter accuracy is needed over temperature, a metal film current sense resistor with ±50ppm/°C is recommended instead of this 1206 J-grade thick film part.
