What are the key features of EEEFC1V221P?
- 220 µF capacitance at 35 V DC rating in a compact 10 mm x 10.2 mm SMD can, delivering high bulk capacitance for output filtering and energy storage on medium-voltage power rails
- Rated 105°C long-life operation in Panasonic FC Series with low leakage current of 0.077 mA, ensuring reliable performance in demanding switching power supply environments
- Surface mount aluminum wet electrolytic construction for high capacitance per unit volume compared to ceramic alternatives at the same voltage and capacitance rating
- RoHS and REACH compliant lead-free design supporting global environmental compliance requirements for electronics used in consumer, industrial, and automotive markets
What is EEEFC1V221P used for?
The EEEFC1V221P is used as an output bulk capacitor in DC-DC switching converters and linear regulators targeting 24 V or 28 V rails, where 220 µF smooths output voltage ripple and reduces response time during load transients. It is also placed on intermediate bus rails in server power supplies and industrial motor drive boards where the 35 V rating provides adequate margin above nominal 24 V systems. The SMD package enables automated assembly in high-volume consumer electronics such as LCD televisions, audio amplifiers, and LED driver boards.

Frequently Asked Questions
What capacitance and voltage rating does the EEEFC1V221P offer?
The EEEFC1V221P is rated at 220 µF capacitance and 35 V DC working voltage, with a leakage current of 0.077 mA. Its 10 mm diameter and 10.2 mm height make it one of the larger SMD aluminum electrolytic capacitors in the Panasonic FC series while still fitting standard automated pick-and-place equipment.
How does the EEEFC1V221P's 35 V rating suit a 24 V bus design?
Using the EEEFC1V221P at a 24 V nominal rail provides approximately 46% derating below its 35 V maximum rating, exceeding the commonly recommended 20–25% minimum derating for aluminum electrolytic capacitors. This margin extends service life significantly, as electrolytic lifetime roughly doubles for every 10°C reduction in effective voltage stress, making it well suited for industrial 24 V power bus filtering.
What is the physical size of EEEFC1V221P and what SMD footprint does it require?
The EEEFC1V221P measures 10 mm in diameter and 10.2 mm in height. PCB designers should use a standard SMD footprint for a 10 mm cylindrical aluminum electrolytic can, allowing at least 1 mm clearance around the body. The overall component height of 10.2 mm must be accounted for in enclosure and board stacking clearance calculations, particularly in slim industrial or consumer housings.
In which power supply topologies is the EEEFC1V221P most commonly used?
The EEEFC1V221P is commonly used as the output filter capacitor in flyback, buck, and half-bridge switching power supply topologies targeting 24 V to 28 V output rails. At 220 µF and 35 V, it provides sufficient bulk storage to maintain output voltage within 1–2% regulation during 1 A to 5 A load steps at typical 100 kHz to 300 kHz switching frequencies in industrial and server power designs.
