Key Features
- 220 µF capacitance at 10V DC rating provides substantial bulk energy storage and filtering on low-voltage power rails in automotive and industrial electronics
- AEC-Q200 qualification confirms the device meets automotive reliability standards for passive components, ensuring consistent performance across the vehicle life cycle
- Anti-vibration 6-pin SMD package mechanically reinforces the capacitor body against mechanical resonance and vibration stress that would degrade single-lead SMD capacitors in automotive environments
- Radial SMD footprint enables automated pick-and-place assembly on standard SMT lines while the vibration-proof structure resists solder-joint fatigue from chassis vibration and shock
- 20% capacitance tolerance with low leakage current design maintains stable filtering performance over the rated -40°C to +105°C automotive temperature range
Applications
The EEE-FK1A221SV is designed for bulk decoupling and output filtering on 5V and 12V automotive power supply rails in ECUs, ADAS sensor modules, and in-vehicle infotainment systems where AEC-Q200 reliability and vibration resistance are mandatory requirements. Its 220 µF capacitance effectively smooths current ripple on DC-DC converter outputs and provides hold-up energy during brief supply interruptions, such as during cold-crank voltage dips in 12V automotive systems. The anti-vibration 6-pin package also makes it suitable for industrial motor-drive control boards and railway electronics subject to continuous mechanical vibration.

Frequently Asked Questions
What capacitance and voltage rating does the EEE-FK1A221SV offer for automotive power rail filtering?
The EEE-FK1A221SV provides 220 µF of capacitance at a rated voltage of 10V DC, with a ±20% tolerance giving an effective capacitance range of 176 µF to 264 µF. At 5V rail applications in automotive ECUs, the 10V rating provides a 2× voltage derating margin—a widely adopted design practice in AEC-Q200 designs that extends capacitor life and maintains capacitance stability over the operating temperature range from -40°C to +105°C.
Why does the EEE-FK1A221SV use a 6-pin anti-vibration package instead of a standard 2-pad SMD body?
Automotive and industrial environments subject PCBs to continuous vibration at frequencies from 10 Hz to 2000 Hz and shock pulses exceeding 50 g, which can crack the solder joints of a conventional 2-pad SMD electrolytic capacitor at the single terminal per polarity. The 6-pin configuration distributes mechanical load across 6 solder joints, dramatically reducing stress per joint and suppressing the resonant oscillation of the tall cylindrical body, extending solder fatigue life by a factor of 3 to 5 compared to 2-pad packages at equivalent vibration amplitudes.
How does AEC-Q200 qualification of the EEE-FK1A221SV support automotive ECU reliability requirements?
AEC-Q200 is the automotive industry standard stress-qualification for passive components, covering endurance tests at 105°C for 2000 hours, temperature cycling from -55°C to +125°C over 1000 cycles, moisture resistance, and solderability verification. A capacitor passing AEC-Q200 is statistically verified to exhibit no more than a defined failure rate (typically below 100 FIT) under automotive operating profiles, giving Tier-1 ECU manufacturers the traceability evidence required by IATF 16949 quality management systems.
What ripple current and ESR characteristics should designers verify for the EEE-FK1A221SV in a DC-DC converter output filter?
For Panasonic FK series electrolytic capacitors in the 220 µF 10V class, equivalent series resistance (ESR) is typically in the range of 50 mΩ to 120 mΩ at 100 kHz and 20°C. Designers should verify that the inductor ripple current in the DC-DC converter output stage does not exceed the capacitor's rated ripple current, which is typically 500 mA to 700 mA at 105°C for this capacitance-voltage class, to avoid exceeding the internal I²R heating limit and degrading capacitor lifetime below the 2000-hour design target.
How does the EEE-FK1A221SV compare to MLCC alternatives for 220 µF bulk capacitance in space-constrained automotive designs?
A single EEE-FK1A221SV provides 220 µF in one SMD footprint, whereas achieving 220 µF at 10V with X5R or X7R MLCCs requires 4 to 6 capacitors of 47 µF or 100 µF per component, increasing BOM count and board area by 3× to 5×. MLCCs offer lower ESR below 5 mΩ and higher resonant frequency, benefiting high-frequency noise suppression above 1 MHz, while the EEE-FK1A221SV excels at bulk energy storage for load transients and hold-up, making the two technologies complementary rather than direct substitutes in automotive power supply designs.
