Frequently Asked Questions
What capacitance and voltage rating does the EEE-FK1K220P provide for power supply designs?
The EEE-FK1K220P is rated at 22 µF capacitance and 80 V working voltage, making it suitable for bulk decoupling and output filtering stages in switched-mode power supplies operating at up to 80 V DC. This combination supports energy storage needs in industrial converters and motor drive circuits without requiring larger through-hole electrolytic capacitors.
How does the SMD package of the EEE-FK1K220P affect PCB assembly and layout?
The EEE-FK1K220P's surface mount package is compatible with automated pick-and-place equipment and reflow soldering, eliminating manual insertion steps required for through-hole electrolytics. Its compact SMD footprint allows placement in tighter PCB areas near switching regulators or motor drive ICs where a 22 µF 80 V capacitor is needed but board space is limited.
In which industrial or high-voltage circuits is the EEE-FK1K220P a good fit?
The EEE-FK1K220P is well suited for 48 V to 80 V bus filtering in DC/DC converters, PFC output stages, and motor controller bulk storage applications. Its 80 V rating provides a comfortable derating margin for 48 V rail designs, while the 22 µF value supplies adequate hold-up energy to prevent output voltage droop during load transients in industrial power electronics.
What low-ESR benefits does the EEE-FK1K220P offer compared to standard aluminum electrolytics?
Panasonic's FK series uses a low-ESR electrolytic construction that reduces resistive heating under high ripple current conditions, extending capacitor life in switching power supply applications. For a 22 µF 80 V SMD capacitor, lower ESR means reduced voltage ripple at the output and less self-heating at typical switching frequencies of 50 kHz to 500 kHz in modern converters.
