Frequently Asked Questions
How does the ERA2AED103X achieve stable 10 kΩ resistance across temperature in precision measurement circuits?
The ERA2AED103X uses a thin-film resistive element with a low temperature coefficient of resistance (TCR), typically ±25 ppm/°C or better, which limits resistance drift to ±0.25 Ω per 10°C change at 10 kΩ. This thin-film technology outperforms thick-film resistors with 100 ppm/°C or higher TCR, making it suitable for precision analog circuits where 0.1% accuracy must be maintained from -55°C to +125°C in instrumentation and medical applications.
What power rating does the ERA2AED103X carry, and how does it limit current in a voltage divider application?
The ERA2AED103X in a 0402 package is typically rated at 0.063 W (63 mW) continuous power dissipation at 70°C ambient temperature. At 10 kΩ resistance, this limits the maximum safe continuous current to approximately 2.5 mA (I = sqrt(P/R) = sqrt(0.063/10000)), and maximum voltage to 25 V across the resistor. In a voltage divider supplying a 3.3 V analog reference, the resistor operates well within these limits with currents typically below 0.5 mA.
When should ERA2AED103X be selected over a standard thick-film 0402 resistor in a high-accuracy DAC output filter?
ERA2AED103X is preferred over thick-film 0402 resistors in DAC output filter applications requiring better than 0.5% total error, such as 16-bit or 18-bit DAC circuits where a 10 kΩ filter resistor must maintain its value within ±50 Ω across the full operating temperature range. Thick-film resistors with 200 ppm/°C TCR drift 200 Ω over a 100°C range, exceeding 2% error, while ERA2AED103X thin-film construction keeps drift below 25 Ω, preserving DAC output accuracy at the system level.
