What are the key features of EEE-FK1E680AP?
- 68 µF capacitance at 25 V in a surface-mount aluminum electrolytic package, providing substantial bulk energy storage without through-hole drilling
- ±20% capacitance tolerance and low ESR characteristic reduce output ripple in DC-DC converter and LDO filter circuits
- SMD construction compatible with standard reflow soldering profiles, enabling fully automated PCB assembly in high-volume production
What is EEE-FK1E680AP used for?
The EEE-FK1E680AP is widely used as an output bulk capacitor in switching power supplies, DC-DC converters, and LDO regulator circuits in consumer electronics, industrial boards, and communication equipment. Its 68 µF at 25 V rating makes it effective for filtering ripple voltages on 5 V to 24 V rails and stabilizing power delivery to processors, FPGAs, and RF modules in compact SMT designs.

Frequently Asked Questions
What are the voltage, capacitance, and tolerance ratings of the EEE-FK1E680AP?
The EEE-FK1E680AP is rated at 68 µF capacitance with a ±20% tolerance and a 25 V working voltage. This combination provides adequate bulk energy storage for filtering switching noise on 5 V, 12 V, and 24 V rails while the ±20% tolerance allows predictable worst-case capacitance planning in DC-DC converter output filter designs.
How does the SMD format of the EEE-FK1E680AP benefit PCB assembly compared to radial through-hole equivalents?
The SMD format eliminates through-hole drilling and wave-soldering steps, reducing PCB layer stackup cost and enabling placement on both sides of the board. In automated reflow lines, a 68 µF SMD aluminum electrolytic can be placed in under 0.1 seconds per part, versus manual or selective soldering for through-hole radial equivalents, cutting assembly labor cost significantly at volumes above 10,000 units.
In which power supply topologies does the EEE-FK1E680AP perform best as an output filter capacitor?
The EEE-FK1E680AP performs best in buck (step-down) and boost DC-DC converter output filters operating at switching frequencies between 100 kHz and 1 MHz, where 68 µF of bulk capacitance at 25 V effectively attenuates ripple to under 50 mV. It is also well-suited as the input bulk capacitor for LDO regulators with output currents up to 3 A.
When would an engineer choose the Panasonic FK series over general-purpose aluminum electrolytic capacitors?
An engineer would choose the Panasonic FK series when a combination of low ESR, long operating life (typically rated 2,000 hours or more at 85°C), and SMD form factor is required in one part. Compared to standard-grade aluminum electrolytics, FK series parts offer improved high-frequency impedance below 1 Ω at 100 kHz, making them preferable in noise-sensitive analog power rails.
