What is ERJP14F4301U used for?
The ERJP14F4301U is well suited for precision voltage dividers in analog-to-digital converter reference circuits, feedback resistors in op-amp and error amplifier configurations, and pull-up resistors in CAN bus and LIN bus interface circuits in automotive systems. Its tight ±1% tolerance and low ±100ppm/°C TCR ensure consistent performance in engine control units (ECUs) and battery management systems operating over the full automotive temperature range of -40°C to +125°C. The 1210 package's 0.5W rating accommodates designs powered from 12V and 24V automotive rails.

Frequently Asked Questions
How accurately does ERJP14F4301U maintain its 4.3kΩ value over a -40°C to +125°C automotive temperature range?
With ±100ppm/°C TCR, the resistance shift over 165°C span (-40°C to +125°C) is at most 100ppm/°C × 165°C = 16,500ppm or ±1.65%. Combined with the initial ±1% tolerance, total resistance variation is approximately ±2.65% over the full automotive temperature range. This level of stability is adequate for voltage divider reference circuits in ECUs where ADC full-scale errors below 3% are acceptable.
In a 12V automotive voltage divider for a 3.3V ADC input, how does ERJP14F4301U pair with a complementary resistor?
To divide 12V down to 3.3V, the ratio needed is 3.3/12 = 0.275. Using the 4.3kΩ ERJP14F4301U as the lower resistor, the upper resistor value is R_upper = R_lower × (Vin/Vout - 1) = 4.3kΩ × (12/3.3 - 1) = 4.3kΩ × 2.636 ≈ 11.3kΩ. A standard 11kΩ or 12kΩ ±1% resistor provides a close ratio. Total current through the divider is 12V/(4.3kΩ + 11kΩ) ≈ 0.78mA, well within component ratings.
How does the ±1% tolerance of ERJP14F4301U compare to the ±5% ERJP14J series for a feedback resistor application?
In an op-amp non-inverting amplifier with gain G = 1 + R_f/R_g, using ±5% tolerance resistors produces worst-case gain error of up to ±10% due to both resistors simultaneously drifting to opposite extremes. Replacing both with ±1% tolerance resistors like ERJP14F4301U limits the gain error to ±2%. For audio and measurement amplifiers where gain accuracy below 2% is required, the ±1% grade is strongly preferred despite a slight cost premium over the ±5% J-suffix variants.
For a high-side current sense amplifier at 24V, what maximum current does ERJP14F4301U handle across its 4.3kΩ sense network?
At 24V applied across the 4.3kΩ ERJP14F4301U, the current would be 24V/4300Ω ≈ 5.6mA and power dissipation is 24V × 5.6mA = 134mW — comfortably under the 0.5W rating with over 3× margin. In a typical high-side sense amplifier, the 4.3kΩ resistor forms part of a gain-setting or input filtering network rather than carrying the full load current, keeping dissipation even lower and well within the 1210 package's thermal limits.
