- Low ±15 ppm/°C temperature coefficient maintains resistance stability across wide temperature ranges
- 0805 SMT package at 2.0 mm × 1.25 mm supports automated assembly in space-constrained precision PCB layouts
Applications
The ERA6APB2491V is a high-precision thin-film resistor used in precision voltage dividers, instrumentation amplifiers, and reference circuits where accurate 2.49 kΩ resistance must hold across temperature variations from -55°C to +155°C. Its ±15 ppm/°C TCR minimizes gain drift in medical devices, test and measurement equipment, and industrial sensors. The 0805 footprint enables seamless integration into standard SMT assembly processes without specialized tooling.

Frequently Asked Questions
How does the ±15 ppm/°C TCR of the ERA6APB2491V affect circuit performance over temperature?
At ±15 ppm/°C, the ERA6APB2491V resistance shifts by only 0.0015% per degree Celsius. Over a 100°C operating range, total resistance drift is limited to ±0.15%, keeping gain and divider ratio errors well below the ±0.1% initial tolerance in precision instrumentation amplifier and ADC reference circuits.
In which precision analog designs is ERA6APB2491V preferred over a standard 1% resistor?
ERA6APB2491V is preferred in 16-bit or 24-bit ADC front-end dividers, precision op-amp feedback networks, and Wheatstone bridge sensors where total error budgets allow less than ±0.2% resistance deviation. A standard 1% resistor would consume the entire error budget without accounting for temperature drift, whereas the ±0.1% thin-film unit leaves margin for other error sources.
What power dissipation limit should designers observe when using ERA6APB2491V in a 5 V circuit?
The resistor is rated at 0.125 W continuous power dissipation. At 2.49 kΩ with a 5 V supply, the dissipated power is approximately V²/R = 10 mW, well within the 125 mW rating. Designers should verify thermal derating above 70°C ambient to avoid exceeding the power limit in high-temperature environments.
