Key Features
- 220 µF capacitance with 63 V rating provides substantial bulk energy storage for power supply output filtering and hold-up
- Aluminum wet electrolytic construction in a 12.5 mm diameter × 13.5 mm height radial can suits standard PCB footprints
- RoHS/REACH-compliant Pb-free (JESD-609 e3) construction meets modern environmental regulations
- Panasonic FK series low-ESR design reduces output voltage ripple in switching power converters and motor drive circuits
Applications
The EEEFK1J221AQ is primarily used as an output bulk capacitor in AC-DC and DC-DC switching power supplies where 220 µF at 63 V provides sufficient energy storage to maintain regulated output voltage during load transients. It is well suited for industrial power converters, motor drive pre-charge circuits, and UPS hold-up circuits where reliable bulk capacitance at elevated voltages is required. The radial leaded package also makes it appropriate for through-hole PCB assembly in power modules and energy storage filter stages.

Frequently Asked Questions
What is the capacitance and voltage rating of the EEEFK1J221AQ, and what power supply output stage does it target?
The EEEFK1J221AQ is rated at 220 µF and 63 V, making it suitable as an output bulk capacitor for power supplies with output rails up to 48 V or 60 V with design margin. In a 48 V DC-DC converter, a single 220 µF capacitor provides approximately 253 µJ of stored energy, supporting transient hold-up and reducing output ripple voltage during load steps.
What are the physical dimensions of the EEEFK1J221AQ, and what PCB footprint does it require?
The EEEFK1J221AQ has a 12.5 mm body diameter and 13.5 mm height in a standard radial can format. The PCB footprint requires two through-holes spaced at the standard 5 mm pitch used for 12.5 mm diameter electrolytic capacitors, with hole diameters of approximately 0.8 mm to 1.0 mm for the leads, matching the most common footprint libraries for this capacitor class.
How does the Panasonic FK series aluminum electrolytic design compare to a standard electrolytic in switching power converter filtering?
The FK series uses a low-ESR aluminum wet electrolytic construction that reduces resistive power dissipation at high ripple current frequencies typical in switching converters operating at 50 kHz to 500 kHz. Lower ESR means less output voltage ripple for a given ripple current and lower self-heating, which directly extends capacitor service life compared to standard general-purpose electrolytic types of the same 220 µF, 63 V rating.
Is the EEEFK1J221AQ RoHS compliant, and what lead time should procurement plan for?
Yes, the EEEFK1J221AQ carries Pb-free and REACH-compliant status (JESD-609 e3), meeting RoHS Directive requirements. Panasonic lists a factory lead time of 21 weeks for this part, so procurement should plan safety stock or place orders well in advance of production builds to avoid supply interruptions, particularly for industrial or long-lifecycle designs that cannot substitute alternative capacitors mid-run.
