What are the key features of EEE-FK1C221P?
- AEC-Q200 automotive-grade reliability rated for 2000 hours at 105°C, suitable for under-hood and infotainment power rails
- 220 µF at 16 V with 300 mA ripple current capability in a compact 8 mm × 6.2 mm SMD footprint
- Tape-and-reel packaging supports high-speed automated reflow assembly in automotive and industrial production lines
What is EEE-FK1C221P used for?
The EEE-FK1C221P is designed for power supply decoupling and output filtering in automotive electronics, including ECUs, infotainment systems, and ADAS modules where 105°C operating temperature and AEC-Q200 qualification are mandatory. Its 220 µF capacitance stabilizes 12 V and lower-voltage rails during load transients caused by motor switching and solenoid actuation in vehicle body control modules. The SMD format and tape-and-reel delivery also make it suitable for high-volume industrial power supply assemblies requiring 16 V bulk capacitance in a compact 8 mm diameter footprint.

Frequently Asked Questions
How does EEE-FK1C221P meet automotive electronics temperature and lifetime requirements?
EEE-FK1C221P is rated for 2000 hours of operation at 105°C, which meets the extended temperature and lifetime requirements specified in AEC-Q200 for automotive passive components. Most standard commercial aluminum electrolytic capacitors are only rated for 1000 hours at 85°C, so the FK series doubles the rated lifetime at a 20°C higher temperature. This makes EEE-FK1C221P suitable for engine control units, power management modules, and body electronics exposed to under-hood temperatures above 85°C.
What ripple current can EEE-FK1C221P handle, and which converter topologies benefit from its 220 µF rating?
EEE-FK1C221P is rated at 300 mA ripple current, making it appropriate for moderate-frequency DC-DC converters switching at 100 kHz or above. The 220 µF capacitance provides sufficient output bulk storage to reduce voltage ripple on 12 V rails in boost converters, buck converters, and flyback power supplies used in automotive body control modules. For applications requiring more than 300 mA ripple, two or more EEE-FK1C221P units placed in parallel can share the ripple current load while keeping the 8 mm diameter footprint manageable.
How does the 8 mm × 6.2 mm SMD package of EEE-FK1C221P compare to equivalent through-hole capacitors for automotive PCB design?
The EEE-FK1C221P SMD package measuring 8 mm diameter and 6.2 mm height eliminates through-hole drilling and enables placement on both sides of the PCB, reducing assembly cost in automotive ECU boards. Equivalent 220 µF, 16 V radial through-hole capacitors typically stand 11 mm or taller with larger radial lead spacing, which consumes more board height in shallow ECU enclosures. The SMD form factor also provides better vibration resistance since it is not cantilevered on long leads, an important advantage for automotive applications subject to engine vibration.
