Frequently Asked Questions
What resistance value and tolerance does the ERA3AEB391V provide for precision voltage divider design?
The ERA3AEB391V is a 390 Ω resistor with 0.1% tolerance and 25 ppm/°C temperature coefficient, allowing designers to build voltage dividers with total divider error below 0.2% across a -55°C to +155°C operating temperature range in precision analog and measurement circuits.
How does the ERA3AEB391V's 25 ppm/°C TCR affect gain accuracy in an instrumentation amplifier feedback network over a 100°C temperature swing?
A 25 ppm/°C TCR means the 390 Ω resistance shifts by at most 0.975 Ω over a 100°C temperature change, causing a gain error of about 0.25% in an instrumentation amplifier feedback network — well within the accuracy budget of 12-bit to 14-bit ADC-based measurement systems.
Can the ERA3AEB391V be substituted for a standard 1% 0603 resistor in a 3.3 V precision reference divider, and what accuracy improvement results?
Replacing a 1% tolerance 0603 resistor with the ERA3AEB391V's 0.1% tolerance reduces initial divider ratio error from up to 1.41% (worst-case two-resistor mismatch) to at most 0.14%, improving reference voltage accuracy by approximately 10x — a meaningful gain for 16-bit ADC front-end designs or precision current-sensing circuits operating at 3.3 V.
