Key Features
- 22 µF 16 V capacitance rating with 105°C rated operating temperature and 2000-hour endurance for automotive and high-temperature applications
- 160 mA rated ripple current in a compact SMD 5 mm x 5.8 mm cylindrical package suitable for surface mount automotive PCBs
- AEC-Q200 automotive-grade qualification ensures reliability in harsh under-hood environments with wide temperature swings
Applications
EEE-FK1C220AR is used in automotive ECU power supply rails, DC-DC converter output filters, and voltage regulator bypass applications where 22 µF bulk capacitance at up to 16 V is needed in a compact SMD form. Its 105°C, 2000-hour life rating and automotive qualification make it suitable for under-hood installations in powertrain control modules and advanced driver assistance systems (ADAS). The SMD package supports wave soldering and automated assembly on automotive-grade PCB production lines.

Frequently Asked Questions
What voltage and capacitance ratings does EEE-FK1C220AR carry, and what temperature grade is it rated for?
EEE-FK1C220AR is rated at 22 µF capacitance and 16 V maximum working voltage, with a 20% tolerance. It operates up to 105°C with a 2000-hour endurance rating, making it suitable for automotive under-hood environments where temperatures regularly exceed 85°C.
Can EEE-FK1C220AR be used in an automotive ECU power supply filter without derating concerns?
Yes, EEE-FK1C220AR carries AEC-Q200 automotive qualification and is rated at 160 mA ripple current with a 2000-hour life at 105°C. In most 12 V automotive ECU power supply circuits at less than 16 V input, the capacitor operates within its rated limits without derating, provided ripple current stays below 160 mA.
How does the 5 mm x 5.8 mm SMD package of EEE-FK1C220AR compare to through-hole alternatives for space-constrained automotive boards?
The SMD cylindrical package (5 mm diameter, 5.8 mm height) eliminates through-hole drilling and allows EEE-FK1C220AR to be placed on the same side as other SMD components, reducing PCB layer count requirements. Compared to a through-hole 22 µF 16 V capacitor of similar rating, the SMD form occupies less board area and integrates into fully automated surface mount assembly lines without separate radial insertion steps.
