Frequently Asked Questions
What capacitance and voltage rating does the EEE-FKA221XAP provide, and how does it compare to through-hole alternatives?
The EEE-FKA221XAP provides 220 µF capacitance at a 10 V DC voltage rating in an SMD package. Compared to through-hole counterparts, the SMD format eliminates lead-forming and reduces board height to under 8 mm, while maintaining equivalent bulk charge storage for power rail stabilization in automated surface-mount assembly lines.
For what switching power supply topologies is the EEE-FKA221XAP 220 µF low-ESR design most beneficial?
In buck and boost converter output stages operating at 100 kHz to 500 kHz, the EEE-FKA221XAP's low-ESR construction minimizes output voltage ripple, often achieving ripple below 50 mV at 1 A load. It is particularly effective in flyback and SEPIC topologies where bulk capacitance of at least 100 µF is needed on a 5 V or lower output rail.
What ripple current handling and temperature range can be expected from the EEE-FKA221XAP?
Panasonic FK-series capacitors like the EEE-FKA221XAP are rated for operating temperatures from -55°C to 105°C and support continuous ripple currents typically in the range of 300 mA to 700 mA at 100 kHz, depending on ambient conditions. The 105°C upper limit extends service life in thermally stressed environments such as automotive auxiliary circuits and industrial enclosures.
How does the SMD footprint of EEE-FKA221XAP simplify high-volume PCB assembly?
The EEE-FKA221XAP SMD package is compatible with standard pick-and-place machines and reflow soldering profiles up to 260°C peak, eliminating the manual insertion step required for 220 µF through-hole capacitors. This reduces assembly cycle time and enables double-sided PCB population, saving up to 30% of board area in dense power supply designs.
When should designers prefer EEE-FKA221XAP over tantalum or MLCC capacitors for 10 V bulk decoupling at 220 µF?
For bulk decoupling needs of 220 µF at 10 V, the EEE-FKA221XAP is a cost-effective alternative to tantalum capacitors, which typically cost 3x to 5x more for equivalent capacitance. Unlike MLCCs, which suffer significant capacitance derating above 6 V bias, aluminum electrolytic capacitors maintain the full rated 220 µF with minimal derating at 10 V applied voltage, making them preferable for stable power rail filtering.
