Key Features
- 330 µF capacitance at 25 V in a compact 8x10.2 mm SMD footprint, optimized for automotive power supply bulk decoupling
- AEC-Q200 automotive-grade qualification with 1000-hour lifetime at 85°C ensures reliability in under-hood and harsh-environment applications
- 270 mA ripple current rating supports efficient filtering in DC/DC converter output stages and ECU power rails
Applications
The EEE-1EA331UAP is used in automotive ECU power supply circuits, ADAS module voltage regulators, and infotainment system bulk decoupling where 330 µF at 25 V in a compact SMD package is required. Its AEC-Q200 qualification and 85°C/1000-hour rating make it suitable for engine-bay electronics subject to thermal cycling and vibration. Industrial SMPS output stages and motor drive inverter bus capacitors also benefit from its combination of high capacitance, automotive reliability, and tape-and-reel availability.

Frequently Asked Questions
What are the voltage, capacitance, and temperature ratings of the Panasonic EEE-1EA331UAP?
The EEE-1EA331UAP is rated at 330 µF capacitance, 25 V working voltage, and ±20% tolerance, with a maximum operating temperature of 85°C and a rated lifetime of 1000 hours at 85°C, meeting AEC-Q200 requirements for automotive SMD electrolytic capacitor applications.
For automotive ECU power supply design, how does the EEE-1EA331UAP's ripple current rating influence component selection?
The EEE-1EA331UAP is rated for 270 mA ripple current at 85°C, which determines how much AC ripple the capacitor can safely handle from an upstream DC/DC converter switching stage; exceeding this value reduces lifetime, so designers must sum all ripple sources and derate to below 270 mA to meet the 1000-hour automotive reliability target.
How does the 8x10.2 mm case size of EEE-1EA331UAP compare to alternative SMD electrolytic options for PCB footprint planning?
At 8 mm diameter and 10.2 mm height, the EEE-1EA331UAP occupies a compact SMD footprint suitable for automated reflow assembly; compared to larger 10x12.5 mm case capacitors with similar 330 µF capacitance, it saves approximately 20% of board area, which is valuable in densely populated automotive ECU and ADAS module layouts.
