What are the key features of ERJT06J681V?
- 680 Ω resistance value ideal for LED current limiting at 3.3 V and 5 V logic supply rails
- 0.25 W power rating in an 0805 SMD package with 2.0 mm length and 0.6 mm profile
- ±200 ppm/°C temperature coefficient ensures consistent resistance in industrial temperature environments
- Pb-free JESD-609 e3 and REACH-compliant for global RoHS regulatory compliance
- 18-week factory lead time — plan procurement 4 to 5 months ahead for production volumes
What is ERJT06J681V used for?
The ERJT06J681V is frequently used as a current-limiting resistor for LEDs and indicator lamps on 3.3 V or 5 V logic boards, a series resistor for UART and GPIO signal conditioning, and a pull-up or pull-down element in digital interface circuits. At 680 Ω on a 5 V rail, it passes approximately 7.4 mA, providing moderate brightness LED drive without excessive power dissipation. The compact 0805 footprint integrates cleanly into high-density SMT layouts alongside microcontrollers and logic ICs.

Frequently Asked Questions
At 5 V, how much LED current does the ERJT06J681V limit, and is that within its power rating?
With a forward-biased LED dropping about 2.0 V, the remaining 3.0 V across the 680 Ω resistor limits current to approximately 4.4 mA, dissipating only 13 mW — well below the 0.25 W rating. Even at 5 V with a 0 V drop load, peak current is 7.4 mA, dissipating 37 mW, still comfortably within spec.
How does the ERJT06J681V's ±200 ppm/°C TCR affect its performance in outdoor industrial equipment?
Across a -40°C to +85°C industrial range (125°C span), the 680 Ω resistance shifts by at most 170 Ω under the ±200 ppm/°C coefficient. For LED limiting and digital pull-up applications, this translates to less than 25% current variation — acceptable for most non-precision indicator and interface applications without requiring closer-tolerance parts.
What procurement lead time should be planned for the ERJT06J681V?
Panasonic lists an 18-week factory lead time for the ERJT06J681V, requiring procurement teams to place orders 4 to 5 months before the production build date. Designers should validate distributor stock levels early in the project cycle or identify an approved 0805 680 Ω alternative with shorter lead times to mitigate supply risk.
Can the ERJT06J681V be used as a series termination resistor for high-speed signal lines?
The 680 Ω value is higher than the typical 22 Ω to 100 Ω range used for series-termination damping on high-speed digital lines, so the ERJT06J681V is not optimal for that role. However, it is well suited for low-frequency signal conditioning, reset pull-ups, and UART TX series resistors on lines where slew-rate limiting rather than impedance matching is the goal, typically at speeds below 1 MHz.
