What is ERJT06J123V used for?
ERJT06J123V is used as a pull-up or pull-down resistor on I2C, SPI, and UART signal lines where 12 kΩ limits bus current while maintaining adequate logic levels. It serves in RC timing networks, bias setting for analog amplifiers, and voltage divider chains for ADC input scaling in microcontroller-based sensor systems. The 0805 package is compatible with standard automated pick-and-place assembly, making it suitable for high-volume consumer electronics, industrial sensors, and IoT module production.

Frequently Asked Questions
How much current flows through ERJT06J123V when used as a 3.3 V pull-up on an I2C bus?
With 12 kΩ resistance and a 3.3 V supply, the pull-up current when the bus is idle and the line is high is 3.3 V / 12 kΩ = 275 µA, which is well within the 0.25 W rating of ERJT06J123V. This current level also falls within the recommended 1 mA to 10 mA range for I2C pull-ups at 400 kHz fast-mode, ensuring adequate rise times on capacitance loads up to 100 pF.
How does the ±200 ppm/°C TCR of ERJT06J123V affect resistance accuracy over an industrial temperature range?
Over a 100°C industrial temperature range from -40°C to +85°C, the ±200 ppm/°C coefficient shifts resistance by up to ±2%, which combined with the initial ±5% tolerance gives a worst-case total deviation of ±7%. For pull-up or bias applications this is acceptable, but precision voltage dividers or current-setting applications requiring better than ±2% total accuracy over temperature should specify a ±1% / ±100 ppm/°C alternative.
When is ERJT06J123V an appropriate choice for RC timing circuits in low-cost microcontroller designs?
ERJT06J123V with its 12 kΩ value pairs with capacitors from 1 nF to 100 nF to produce RC time constants from 12 µs to 1.2 ms, covering debounce filters, reset delay circuits, and PWM smoothing networks at frequencies from 1 kHz to 100 kHz. Its ±5% tolerance is adequate for timing where a 5% variation in period is acceptable, and the 0.25 W rating comfortably handles charge/discharge currents in these RC networks.
What is the maximum continuous current ERJT06J123V can carry before exceeding its power rating?
The maximum continuous current at room temperature is limited by the 0.25 W power rating: I = sqrt(P/R) = sqrt(0.25 W / 12000 Ω) = approximately 4.6 mA. This restricts use to low-current signal and bias paths; for applications requiring currents above 4 mA through 12 kΩ, a larger 0402 or 1206 package variant rated at 0.5 W or higher must be used to avoid thermal stress and long-term reliability degradation.
