What is ERJT08J512V used for?
The ERJT08J512V 5.1 kΩ resistor is commonly used in microcontroller I2C pull-up networks, input signal conditioning voltage dividers, and base biasing resistors for BJT transistors in consumer electronics and industrial boards. Its 0.33 W 1206 form factor delivers reliable performance in switching power supply feedback dividers and GPIO protection circuits operating at supply voltages up to several tens of volts. The ±200 ppm/°C coefficient makes it appropriate for ambient temperature environments where tight resistance accuracy is not critical.

Frequently Asked Questions
What is the resistance and tolerance of the ERJT08J512V and how does this affect I2C pull-up sizing?
The ERJT08J512V is a 5.1 kΩ ±5% resistor, meaning the actual resistance can range from approximately 4.85 kΩ to 5.36 kΩ. For I2C bus pull-up applications at 3.3 V or 5 V with bus speeds up to 400 kHz, a 5.1 kΩ pull-up is within the recommended range of 1 kΩ to 10 kΩ defined by the I2C specification, and ±5% tolerance has negligible impact on pull-up behavior at those speeds.
How much continuous power can the ERJT08J512V dissipate and what does that imply for maximum current?
The ERJT08J512V is rated for 0.33 W continuous power dissipation. For a 5.1 kΩ resistor at 0.33 W, the maximum continuous current is approximately 8 mA (I = sqrt(P/R)). In practice, this limits the maximum voltage across the resistor to about 40 V, which is suitable for most low-voltage control and signal conditioning applications.
Which PCB assembly process is the ERJT08J512V designed for?
The ERJT08J512V uses the 1206 SMD package with dimensions of 3.2 mm x 1.6 mm x 0.6 mm, designed for automated surface-mount technology assembly. It is compatible with standard reflow soldering using lead-free solder paste, and the JESD-609 e3 Pb-free rating confirms suitability for lead-free peak reflow temperatures typically up to 260°C.
When would you select a 5.1 kΩ resistor like the ERJT08J512V instead of a 4.7 kΩ or 5.6 kΩ value?
A 5.1 kΩ value is preferred in designs where the E24 resistor series is specified, as 5.1 kΩ is a standard E24 value positioned between 4.7 kΩ and 5.6 kΩ. It offers approximately 8% higher impedance than 4.7 kΩ, reducing pull-up current consumption by about 8% in I2C or open-drain bus designs powered at 3.3 V or 5 V. This can matter in battery-powered applications targeting 10 µA to 1 mA standby current budgets.
