Applications
The EEE-1AA470WAR is an automotive-grade SMD aluminum electrolytic capacitor used for bulk decoupling, power supply filtering, and energy buffering in vehicle electronic control units (ECUs), infotainment modules, and ADAS sensor boards. Its 47 µF at 10 V with 85°C/1000 h rating makes it suitable for engine control modules and body electronics where vibration and temperature cycling demand long-life components. Designers also use it in 12 V automotive subsystem power rails needing compact polarized capacitors qualified to AEC standards.

Frequently Asked Questions
What are the key electrical specifications of the EEE-1AA470WAR capacitor?
The EEE-1AA470WAR is a 47 µF aluminum electrolytic capacitor rated at 10 V with a 20% capacitance tolerance. It has a maximum ripple current of 47 mA and a rated lifetime of 1000 hours at 85°C, in a compact 5 x 5.4 mm SMD case suitable for automotive PCB assembly.
Why is the EEE-1AA470WAR preferred in automotive ECU designs over standard-grade electrolytic capacitors?
The EEE-1AA470WAR carries automotive-grade qualification, providing a 1000-hour rated lifetime at 85°C and meeting the environmental stress requirements typical for AEC-qualified passive components. Standard-grade capacitors often specify shorter lifetimes or lower operating temperatures, making them unsuitable for under-hood automotive applications where thermal cycling, vibration, and humidity are continuous challenges.
How does the 5 x 5.4 mm SMD case size affect the placement of EEE-1AA470WAR in compact automotive PCBs?
The 5 x 5.4 mm SMD cylindrical case allows automated reflow assembly on densely populated automotive PCBs where through-hole capacitors would require larger keep-out zones and prevent double-sided placement. At 47 µF and 10 V in this footprint, it provides adequate bulk capacitance for low-voltage digital supply rails without consuming excessive board area in ECU and sensor module designs.
For 12 V automotive power rails, what decoupling role does the EEE-1AA470WAR serve, and what limits its use?
The EEE-1AA470WAR is used as a local bulk decoupling capacitor on 5 V to 10 V regulated rails derived from a 12 V automotive supply, absorbing load transients with its 47 µF capacitance. Its 10 V voltage rating limits direct connection to unregulated 12 V bus lines, requiring a downstream regulator; its 47 mA ripple current should also be checked against switcher output ripple requirements to avoid premature aging.
