Applications
The EEEFC1A330R is widely used as a bulk decoupling capacitor on 5 V to 10 V power rails in switching power supply output filters, where its 33 µF capacitance and low leakage reduce output ripple below 50 mV peak-to-peak. It is also suitable as a bypass capacitor near voltage regulator outputs in industrial PCBs where the 1000-hour 105 °C rating ensures long service life. Its SMD footprint makes it compatible with automated reflow soldering processes in consumer electronics and IoT device production.

Frequently Asked Questions
What is the rated lifetime of the EEEFC1A330R and at what temperature is it characterized?
The EEEFC1A330R carries a 1000-hour rated lifetime at 105 °C, which is the standard endurance test temperature for aluminum electrolytic capacitors per IEC 60384-4. Operating at lower temperatures such as 85 °C effectively doubles or quadruples lifespan using the Arrhenius 10 °C rule, making it viable for long-service-life applications exceeding 5000 hours.
How does the 3.3 µA leakage current of the EEEFC1A330R affect battery-powered designs?
At 3.3 µA leakage on a 33 µF 10 V capacitor, the self-discharge contribution to standby power is approximately 33 µW on a 10 V rail, negligible in most applications. In a battery-powered device running from a 1000 mAh cell, this leakage accounts for less than 0.003 mA of quiescent drain, ensuring the capacitor does not measurably reduce battery run time even in low-power IoT designs targeting sub-10 µA sleep current.
What PCB footprint does the EEEFC1A330R require and how does it fit in high-density SMD layouts?
The EEEFC1A330R uses a radial SMD footprint corresponding to a 5 mm body diameter and 5.4 mm height. The IPC-standard land pattern for this size is approximately 6.6 mm × 4.6 mm, occupying about 30 mm² of PCB area — roughly one-third the area of a through-hole equivalent and compatible with standard 0402 to 0805 component pick-and-place reflow assembly lines.
When should I choose the EEEFC1A330R over a 33 µF ceramic MLCC for power rail filtering?
A 33 µF MLCC in X5R or X7R dielectric loses 50% to 70% of capacitance under 10 V DC bias, effectively delivering only 10 µF to 16 µF in circuit. The EEEFC1A330R maintains its full 33 µF rating at 10 V because aluminum electrolytic capacitors do not exhibit significant voltage-coefficient derating, making it the correct choice for DC-bias-sensitive output filter stages in 5 V to 10 V switching converters.
