Frequently Asked Questions
How does the ±50 ppm/°C temperature coefficient of the MBA02040C4300FC100 affect resistance drift in a precision voltage divider?
At ±50 ppm/°C, a 430 Ω resistor changes by at most 21.5 mΩ per degree Celsius, which in a precision voltage divider translates to a ratio error below 0.005% over a 10 °C temperature swing. This level of stability is adequate for 16-bit ADC reference circuits and bridge-measurement networks operating across industrial temperature ranges.
What is the maximum continuous power dissipation and AC voltage rating of this resistor?
The MBA02040C4300FC100 is rated for 0.4 W continuous power dissipation and up to 200 V AC applied voltage. Designers should derate power by approximately 50% above 70 °C ambient to stay within the maximum junction temperature, ensuring long-term reliability in demanding industrial or automotive-adjacent environments.
For which precision circuit topologies is a thin-film axial resistor preferred over a carbon-film alternative?
Thin-film resistors like the MBA02040C4300FC100 offer lower noise (typically below 0.1 µV/V excess noise index), tighter tolerances down to ±1%, and lower TCR around ±50 ppm/°C compared to carbon-film types that may exceed ±200 ppm/°C. They are preferred in low-noise amplifiers, precision current sensing, Wheatstone bridge sensors, and audio signal chains where accuracy and stability over temperature are paramount.
Can the MBA02040C4300FC100 be used in automated PCB assembly, and what are its lead dimensions?
Yes, the component supports automated axial-lead insertion with 0.5 mm diameter leads and 29 mm lead length, compatible with standard axial-lead forming and insertion machines. The 1.6 mm package diameter fits grid spacings from 5 mm to 25 mm, accommodating both dense and standard through-hole PCB pitches in industrial and consumer production lines.
