Frequently Asked Questions
How much resistance drift should a designer expect from the ERA6APB3321V across a 0°C to +70°C industrial temperature range?
With a temperature coefficient of ±15 ppm/°C, the ERA6APB3321V drifts at most 15 parts per million per degree Celsius. Over a 70°C span (0°C to +70°C), the maximum resistance change is 70 × 15 = 1050 ppm, which equals approximately ±3.5 Ω on the nominal 3.32 kΩ value. This level of stability is sufficient for 0.1% precision analog gain-setting networks and voltage dividers in industrial instrumentation.
In which precision analog circuit topologies is the ERA6APB3321V's 3.32 kΩ ±0.1% value most commonly used?
The 3.32 kΩ value at ±0.1% is commonly used in E192 preferred-value resistor divider networks for precision voltage references, op-amp non-inverting gain stages targeting gains near 3.32 or 4.32, and bridge circuit arms in load cell and strain gauge instrumentation. The tight ±0.1% tolerance ensures the ratio matching needed for sub-0.1% gain error in 16-bit or 18-bit ADC front-end signal conditioning designs.
How does the ERA6APB3321V's thin-film construction differ from thick-film resistors in terms of noise and stability?
Thin-film resistors like the ERA6APB3321V use a sputtered metallic film that is far more uniform than the fired-paste thick-film process, resulting in current noise of typically below -30 dB (0.1 µV/V) compared to -10 to 0 dB for thick-film types. This 20-40 dB noise advantage matters in low-level sensor amplification stages operating below 10 mV full-scale, where thick-film resistor noise would degrade SNR by measurable amounts at 16-bit resolution.
What is the power dissipation limit of the ERA6APB3321V, and how does it constrain the maximum signal voltage across the resistor?
The ERA6APB3321V is rated at 0.125 W maximum power dissipation. With a 3.32 kΩ resistance, the maximum continuous voltage across the resistor is calculated as V = √(P×R) = √(0.125 × 3320) ≈ 20.4 V. Designers should stay below this voltage in circuit operation and derate to 70% (about 14.3 V maximum) at elevated ambient temperatures above 70°C to maintain long-term reliability.
