Frequently Asked Questions
What are the key electrical specifications of the RS Pro 7111784 aluminium electrolytic capacitor?
The RS Pro 7111784 has a capacitance of 4.7 µF and a maximum DC voltage rating of 160 V with a rated lifetime of 1000 hours. Its 6.3 mm diameter by 11 mm height radial body fits standard PCB footprints used in switch-mode power supply and AC-DC rectifier output filter stages.
In which high-voltage power supply circuit positions is the 7111784 capacitor most commonly placed?
The 7111784 is typically placed at the DC output stage of AC-DC bridge rectifiers, across the rails in fly-back or forward converter auxiliary outputs, and in LED driver circuits operating at bus voltages up to 160 V DC. The 4.7 µF capacitance provides moderate bulk energy storage and ripple filtering at these voltage levels.
How does the 1000-hour lifetime rating of the 7111784 affect its suitability for industrial versus consumer applications?
A 1000-hour rated lifetime at maximum temperature is typical for general-purpose aluminium electrolytic capacitors and is sufficient for consumer electronics, prototype builds, and low-duty industrial equipment operating below 85°C ambient. High-reliability industrial applications running continuously at elevated temperatures above 70°C may require capacitors with 2000-hour or 5000-hour ratings at the same 160 V and 4.7 µF specification.
When should a designer choose the 7111784's 4.7 µF / 160 V rating over a higher-capacitance lower-voltage alternative in a switching supply design?
The 4.7 µF at 160 V is chosen when the DC bus voltage exceeds 100 V, as lower-voltage parts with larger capacitance in the same 6.3 mm x 11 mm body cannot safely handle the rail. In flyback converter designs with 85 V to 265 V AC input, the 160 V rating provides adequate derating margin on the secondary output rail, while 4.7 µF delivers sufficient holdup time for low-current auxiliary supplies below 50 mA.
