Frequently Asked Questions
What resistance tolerance and temperature coefficient does the ERA3AEB121V provide for precision circuit designs?
The ERA3AEB121V features 120 Ω resistance with a ±0.1% tolerance and a temperature coefficient of ±25 ppm/°C. This combination ensures minimal resistance drift across the operating temperature range, making it suitable for precision voltage dividers, reference networks, and measurement applications requiring stable, accurate resistor values.
How does the ERA3AEB121V's 0603 package dimensions compare to other resistor sizes, and what board space does it require?
The ERA3AEB121V uses a standard 0603 rectangular package measuring 1.6 mm in length, 0.8 mm in width, and only 0.45 mm in height. This small footprint allows for high-density component placement on multilayer PCBs, saving significant board area compared to 0805 or 1206 resistors while maintaining precision thin-film performance.
In which precision measurement or analog signal-chain applications is the ERA3AEB121V a strong fit?
With its 120 Ω at ±0.1% tolerance and ±25 ppm/°C drift, the ERA3AEB121V excels in ADC reference dividers, instrumentation amplifier gain networks, current-sense shunt circuits operating at low currents, and Wheatstone bridge configurations in industrial sensors and medical diagnostic equipment where resistor accuracy directly impacts measurement quality.
What is the typical factory lead time and compliance status for the ERA3AEB121V?
The ERA3AEB121V carries a factory lead time of 12 weeks and is both RoHS and REACH compliant. The JESD-609 code e3 confirms lead-free solder compatibility. Global stocking at major distributors reduces effective procurement wait times, supporting production schedules for industrial, telecommunications, and consumer precision electronics with up to 14 years estimated time of life remaining.
