What are the key features of ERJT08J2R7V?
- 2.7 Ω low-resistance value for current sensing and source-degeneration circuit topologies
- 0.33 W power rating in a 1206 (3.2 × 1.6 mm) SMD package suitable for moderate current paths
- Asymmetric -100 to +600 ppm/°C TCR characteristic of thick-film low-value resistors
- Thick-film rectangular construction for automated high-volume pick-and-place assembly
- REACH and RoHS compliant with Pb-free (e3) termination
What is ERJT08J2R7V used for?
The ERJT08J2R7V is used in low-value current sense resistor positions, source-degeneration networks for transistor biasing, and inrush current limiting in power supply designs. At 2.7 Ω and 0.33 W, it can handle up to 350 mA continuously, making it suitable for battery charging circuits, motor driver snubbers, and audio amplifier emitter-degeneration stages. The 1206 package provides good thermal dissipation for sustained moderate-current operation on standard FR4 PCBs.

Frequently Asked Questions
How much current can the ERJT08J2R7V continuously carry within its power rating?
At 0.33 W power limit and 2.7 Ω resistance, the maximum continuous current is approximately 350 mA (√(0.33/2.7)). This makes the ERJT08J2R7V suitable for current-limiting and source-degeneration applications in moderate-current circuits up to 350 mA.
What voltage drop does the ERJT08J2R7V introduce in a 200 mA current path?
At 200 mA, the ERJT08J2R7V drops 0.54 V (200 mA × 2.7 Ω) and dissipates 108 mW. Both values remain within the 0.33 W rating with comfortable margin, making it suitable for inrush-limiting and emitter-degeneration resistor positions in linear circuits.
What is the significance of the asymmetric -100 to +600 ppm/°C temperature coefficient for the ERJT08J2R7V?
The asymmetric TCR of -100 to +600 ppm/°C means resistance can rise more significantly with increasing temperature than it falls with cooling. Over a 100 °C range, the 2.7 Ω value could shift by up to 1.62 Ω in the positive direction, which designers should account for in precision current-sense applications.
Is the ERJT08J2R7V a good choice for emitter-degeneration resistors in BJT amplifier stages?
Yes. A 2.7 Ω emitter-degeneration resistor stabilizes BJT bias against beta variations and temperature drift. At typical emitter currents of 10 mA to 100 mA, the ERJT08J2R7V dissipates 0.27 mW to 27 mW — well within the 0.33 W limit — while improving amplifier linearity.
