Applications
The EEE-FKA331XSP is designed for bulk decoupling and ripple filtering on 5 V and lower supply rails in automotive ECUs, infotainment systems, and ADAS sensor boards that must operate reliably at 105°C. Its 330 µF capacitance and 0.34 Ohm ESR make it effective at suppressing voltage transients caused by microcontroller wakeup events and CAN bus transceiver switching on 3.3 V and 5 V logic rails. The automotive-qualified SMD package also suits industrial control equipment, motor drive boards, and telecom power supply modules requiring long-life bulk capacitance in a 6.3 mm footprint.

Frequently Asked Questions
How does the 0.34 Ohm ESR of EEE-FKA331XSP affect ripple voltage on a 5 V automotive ECU power rail?
With an ESR of 0.34 Ohm and a ripple current rating of 280 mA, the EEE-FKA331XSP produces a maximum ripple voltage contribution of approximately 95 mV at full rated ripple current (280 mA × 0.34 Ohm). On a 5 V rail with a ±5% tolerance, the allowable ripple is 250 mV, leaving ample margin. For applications with higher ripple currents exceeding 280 mA, paralleling two EEE-FKA331XSP units halves the effective ESR to 0.17 Ohm and doubles the ripple current capacity to 560 mA.
Why is EEE-FKA331XSP preferred over a standard commercial-grade 330 µF capacitor in automotive infotainment power design?
EEE-FKA331XSP carries AEC-Q200 automotive qualification and a rated lifetime of 2000 hours at 105°C, whereas standard commercial-grade aluminum electrolytic capacitors are typically rated for only 1000 hours at 85°C. Automotive infotainment modules mounted near the dashboard can experience ambient temperatures exceeding 85°C during summer, making the 105°C rating necessary for reliable long-term operation. The FK series automotive grade also undergoes stricter incoming quality control for solderability and moisture resistance, reducing field failure rates in vehicles with 10-year design life requirements.
How does the 6.3 mm × 7.7 mm SMD footprint of EEE-FKA331XSP compare to a through-hole 330 µF, 10 V capacitor for modern PCB layouts?
The EEE-FKA331XSP SMD package is 6.3 mm in diameter and 7.7 mm tall, which is significantly shorter and narrower than typical radial through-hole 330 µF, 10 V capacitors that often measure 8 mm diameter and 11.5 mm height. The lower height allows EEE-FKA331XSP to fit within automotive ECU enclosures with board-to-board clearances below 10 mm. SMD placement also eliminates through-hole drilling, reducing PCB cost in high-volume automotive production runs while improving mechanical robustness against vibration compared to tall through-hole components mounted on long leads.
