- 5.1kΩ ±0.1% tolerance thin-film resistor in 0402 (1.0 mm × 0.5 mm) SMT package for precision analog signal conditioning
- ±25 ppm/°C temperature coefficient maintains resistance within 0.25% over 0 to 100°C industrial temperature range
- 63mW rated power in compact 0402 package with RoHS-compliant e3 termination finish for lead-free SMT assembly
Applications
The ERA2AEB512X precision thin-film resistor is used in high-accuracy voltage dividers, feedback networks, and gain-setting circuits in instrumentation amplifiers, data acquisition systems, and medical measurement equipment where ±0.1% resistance tolerance and ±25ppm/°C TCR minimize offset and gain errors. Its 0402 package allows integration into space-constrained analog front-end boards without sacrificing resistance accuracy. The e3 RoHS-compliant finish makes it suitable for global electronics manufacturing in precision test equipment, industrial sensors, and aerospace control modules.

Frequently Asked Questions
How much resistance change does ERA2AEB512X exhibit over a 100°C temperature span given its ±25 ppm/°C TCR?
With a TCR of ±25 ppm/°C and a nominal resistance of 5.1kΩ, the ERA2AEB512X changes resistance by at most 25 ppm/°C × 100°C = 2500 ppm, equivalent to 0.25% or approximately ±12.75Ω over a 100°C span. In a precision voltage divider biased at 5V, this translates to an output voltage drift of less than 12.5mV, supporting system-level accuracy requirements below 0.5% in instrumentation and sensor signal conditioning circuits.
For a precision gain-setting network, how does ERA2AEB512X ±0.1% tolerance compare to standard 1% thick-film resistors?
ERA2AEB512X offers ±0.1% tolerance — 10 times tighter than standard 1% thick-film resistors in the same 0402 package. In an instrumentation amplifier gain equation G = 1 + 2R/Rgain, using 1% resistors introduces up to 2% gain error while ±0.1% thin-film resistors reduce this to 0.2%, critical for 12-bit to 16-bit ADC-based data acquisition where a 1% gain error consumes 40 to 164 LSBs of the measurement range.
What power dissipation limit must designers respect when using ERA2AEB512X at 5V in a voltage divider?
ERA2AEB512X is rated at 63mW maximum power dissipation in the 0402 package. In a 5V voltage divider using two 5.1kΩ resistors in series, the total current is 5V / 10.2kΩ = 0.49mA and power per resistor is 0.49mA × 2.45V = 1.2mW — well within the 63mW rating. However, in high-impedance dividers with lower resistance values or elevated supply rails above 25V, designers must verify P = V²/R does not exceed 63mW, especially at elevated ambient temperatures above 70°C.
When is ERA2AEB512X preferable to a 0603 precision resistor for compact PCB designs?
ERA2AEB512X in 0402 (1.0 mm × 0.5 mm) is preferable to a 0603 (1.6 mm × 0.8 mm) precision resistor when PCB area is critically constrained, for example in wearable medical devices or miniaturized sensor modules where 0603 footprints exceed available routing channels. The 0402 package reduces pad area by approximately 60% versus 0603 while maintaining the same ±0.1% tolerance and ±25 ppm/°C TCR, though designers must confirm their SMT assembly process supports 0402 placement accuracy within ±0.1 mm.
