What are the key features of ERA-6ARB4991V?
- Ultra-precision 0.1% tolerance on 4.99 kΩ ensures minimal gain error in precision amplifier, ADC reference, and bridge measurement networks
- Low 25 ppm/°C temperature coefficient maintains stable resistance from -55°C to +155°C, reducing drift in industrial and medical designs
- 0805 thin-film SMD format enables automated high-volume PCB assembly with excellent adhesion and consistent solderability
What is ERA-6ARB4991V used for?
The ERA-6ARB4991V is suited for precision voltage dividers, gain-setting resistor networks, and sensor signal conditioning circuits where a stable 4.99 kΩ reference is critical. Its 0.1% tolerance and 25 ppm/°C TCR make it ideal for use in medical diagnostic equipment, 16-bit and higher ADC reference chains, and industrial measurement systems. The compact 0805 SMT footprint supports integration into high-density PCBs with automated pick-and-place assembly.

Frequently Asked Questions
What resistance value and tolerance does the ERA-6ARB4991V deliver for precision voltage divider designs?
The ERA-6ARB4991V provides a nominal resistance of 4.99 kΩ with a 0.1% tolerance, meaning the actual value stays within ±4.99 Ω. This tight tolerance ensures minimal ratio error in precision voltage dividers and gain networks used in instrumentation amplifiers and high-accuracy data acquisition systems.
How does the ERA-6ARB4991V perform in designs requiring stable resistance across industrial temperature ranges?
With a 25 ppm/°C temperature coefficient, the ERA-6ARB4991V shifts by only 0.125 Ω per degree Celsius at 4.99 kΩ. Across a full industrial range of -40°C to +125°C, total drift is approximately 20 Ω, making it far more stable than standard 100-200 ppm/°C thick-film resistors in precision sensor interface and measurement circuits.
When should a designer choose the ERA-6ARB4991V over a standard thick-film 0805 resistor with similar resistance value?
A designer should choose the ERA-6ARB4991V when circuit accuracy requires less than 0.1% resistance tolerance and drift below 25 ppm/°C, such as in 16-bit ADC reference resistor networks, bridge sensor excitation circuits, or medical-grade signal conditioning. Standard thick-film 0805 resistors typically offer 1% tolerance and 100-200 ppm/°C TCR, introducing 10-20 times more error in precision designs.
