Frequently Asked Questions
How does the ±0.1% tolerance of ERA2AEB4990X compare to standard 1% resistors in precision gain-setting circuits?
The ERA2AEB4990X offers ±0.1% tolerance on its 499 Ω resistance, which is 10 times tighter than standard 1% resistors. In precision amplifier gain-setting or voltage divider networks, this tighter tolerance reduces systematic errors and improves circuit accuracy, particularly in 16-bit or higher resolution data acquisition systems where small resistor mismatches affect measurement quality.
What is the maximum power the ERA2AEB4990X can safely dissipate, and how does it affect current-sense designs?
The ERA2AEB4990X is rated for 63 mW continuous power dissipation in its 0402 package. At 499 Ω, this limits the safe continuous current to approximately 11.2 mA (√(63 mW / 499 Ω)). Designers using it in current sensing or load resistor roles must ensure the circuit keeps power below 63 mW with appropriate derating margins.
How does the ±25 ppm/°C temperature coefficient affect ERA2AEB4990X performance across an industrial temperature range?
With a ±25 ppm/°C TCR, the 499 Ω resistance shifts by at most ±12.5 ppm per degree Celsius. Over an industrial temperature span of -40°C to +85°C (125°C range), maximum drift is approximately ±3125 ppm, or about ±1.56 Ω. This drift level is acceptable for many industrial measurement circuits but may require additional calibration in extreme precision applications.
What procurement factors should engineers consider when ordering ERA2AEB4990X for a production program?
The factory lead time for ERA2AEB4990X is listed at 12 weeks, so procurement teams must plan ahead for production runs. The 0402 package and ±0.1% tolerance thin-film type is not always in local distributor stock. Engineers should confirm REACH compliance, request certificates of conformance, and consider safety stock to avoid supply interruptions in time-sensitive programs.
