Key Features
- 2.4 Ohm low-resistance value at 5% tolerance for current sensing, inrush limiting, and power stage applications
- 0.66 W power rating in 1206 package dissipates more heat than standard 0.25 W resistors in the same footprint
- Temperature coefficient of -100 to +600 ppm/°C for predictable resistance behavior across industrial temperature ranges
- RoHS and REACH compliant lead-free thick-film construction for global environmental certification
Applications
The ERJP08J2R4V is suited for current-limiting resistors in LED driver circuits, snubber networks in power switching stages, and inrush current limiting in power supply designs where a 2.4 Ohm resistor must handle up to 0.66 W of continuous dissipation. Its low resistance enables efficient current sensing in motor control circuits and DC-DC converter output stages. The 1206 SMT package supports high-volume automated assembly in industrial and consumer electronics production.

Frequently Asked Questions
What is the resistance and power rating of the ERJP08J2R4V and which power applications is it suited for?
The ERJP08J2R4V has a resistance of 2.4 Ohm with 5% tolerance and a power rating of 0.66 W. This combination is well suited for LED current-limiting resistors, inrush current limiters, and snubber networks in switching power supplies where the resistor must continuously dissipate heat in a compact 1206 surface-mount package.
How can the ERJP08J2R4V be used for current sensing in a motor driver circuit?
At 2.4 Ohm, the ERJP08J2R4V generates a voltage drop of 240 mV per 100 mA of current, which is measurable by a standard microcontroller ADC with 3.3 V reference. Placing the resistor in series with the motor return path creates a low-side current sense point that can be sampled at sub-microsecond intervals for overcurrent protection and speed control feedback.
What temperature coefficient does the ERJP08J2R4V have and how does it affect resistance stability?
The ERJP08J2R4V has a temperature coefficient of -100 to +600 ppm/°C. Over a 50°C temperature rise from ambient, the resistance can shift by up to 3%, which is within the 5% initial tolerance. For non-precision current-limiting applications this drift is acceptable, but designers of precision current sense circuits should account for this variation in their error budget.
How does the ERJP08J2R4V compare to wirewound resistors for inductive snubber or power dissipation roles?
The ERJP08J2R4V is a thick-film chip resistor with essentially non-inductive construction, making it preferable to wirewound resistors in high-frequency snubber networks where inductive parasitics would reduce snubbing effectiveness above a few MHz. Its 0.66 W rating in a 1206 package meets most snubber dissipation requirements, and the surface-mount format eliminates the through-hole drilling cost associated with wirewound alternatives.
