Frequently Asked Questions
What resistance value and package size does the ERA2AEB3922X provide for automotive circuit designs?
The ERA2AEB3922X provides a 39.2 kΩ resistance in a 0402 surface-mount package measuring 1.0 mm × 0.5 mm with a maximum height of 0.35 mm. This combination allows high-density placement in automotive PCBs where space is at a premium, and the AEC-Q200 qualification guarantees performance from -55°C to +155°C across the automotive temperature range.
How does the thin-film construction of the ERA2AEB3922X benefit a precision voltage divider compared to a standard thick-film 0402 resistor?
Thin-film technology delivers a significantly lower temperature coefficient of resistance—typically ±25 ppm/°C or better—compared to ±100 ppm/°C or more for common thick-film 0402 parts. For a 39.2 kΩ divider biasing a precision ADC reference, this means the ratio shift across a 100°C temperature swing is reduced from roughly 1% to under 0.25%, improving measurement accuracy without adding calibration overhead.
Is the ERA2AEB3922X compliant with RoHS and REACH regulations, and what is the typical lead time?
Yes, the ERA2AEB3922X carries a Pb-free code of 'Yes' and is REACH Compliant, making it suitable for eco-design directives in the EU and other regulated markets. The factory lead time is 12 weeks, so procurement teams should plan buffer stock for high-volume automotive or industrial programs to avoid supply gaps during the 39.2 kΩ 0402 thin-film build schedule.
Can the ERA2AEB3922X be used as a pull-up resistor in an I²C bus running at 3.3 V, and what current does it set?
With a 39.2 kΩ resistance at a 3.3 V supply, the ERA2AEB3922X sets an I²C pull-up current of approximately 84 µA, which is within the 1 µA to 3 mA range specified by the I²C standard for standard-mode and fast-mode buses. While suitable for low-capacitance buses below 50 pF, designers targeting 400 kHz fast-mode operation with longer PCB traces should verify the RC time constant does not exceed the 0.3 µs maximum edge rise time.
