Frequently Asked Questions
What capacitance and voltage rating does the EEE-FK1V220AR provide, and which supply rails is it appropriate for?
The EEE-FK1V220AR is rated at 22 µF and 35 V, making it appropriate for filtering and decoupling on supply rails up to approximately 24 V. The 35 V rating gives adequate headroom for 12 V and 24 V power rails commonly found in industrial and consumer electronics designs.
How does the Panasonic FK series aluminum electrolytic capacitor compare to a ceramic capacitor for bulk power decoupling at 22 µF?
At 22 µF, the EEE-FK1V220AR aluminum electrolytic capacitor typically offers a lower cost per µF than a ceramic capacitor of the same value and voltage rating, though it has higher ESR. For bulk decoupling and hold-up energy storage on 12 V to 35 V rails, electrolytics remain the practical choice due to cost and energy density.
Is the EEE-FK1V220AR packaged for automated SMT assembly, and does it comply with RoHS requirements?
Yes, the EEE-FK1V220AR is supplied in a radial SMD package suitable for standard pick-and-place automated SMT assembly. Panasonic designs the FK series with RoHS-compliant materials to meet lead-free construction requirements for shipment into the EU and other regulated markets.
In a switching power supply design, what role does a 22 µF output capacitor like the EEE-FK1V220AR play in output ripple reduction?
In a switching power supply, a 22 µF aluminum electrolytic output capacitor filters the high-frequency switching ripple from the inductor current, reducing output voltage ripple to millivolt levels. The 35 V rated EEE-FK1V220AR can handle the ripple current stress typical of converters switching at 100 kHz to 500 kHz on 5 V to 24 V output rails.
