Key Features
- 470 µF capacitance at 25 V in a compact 10 x 10.2 mm SMD footprint delivers high energy density for power supply bulk decoupling
- Low 0.15 ohm ESR reduces power dissipation and supports 750 mA ripple current without excessive heating
- 3000-hour rated lifetime at 125 degrees C enables deployment in automotive and industrial applications with elevated operating temperatures
- Surface-mount tape-and-reel packaging is compatible with automated SMT pick-and-place assembly for high-volume production
Applications
The EEE-TC1E471UP is used as a bulk decoupling and energy storage capacitor in switching power supply output stages, DC-DC converter filters, and motor drive bus capacitors operating at 25 V. Its low ESR and 750 mA ripple current rating make it effective in point-of-load regulators on industrial backplanes, server motherboards, and automotive body control modules. The 3000-hour 125-degree C lifespan ensures reliable operation over extended product lifetimes in thermally demanding enclosures.

Frequently Asked Questions
What are the key electrical specifications of the EEE-TC1E471UP capacitor?
The EEE-TC1E471UP is rated 470 µF capacitance at 25 V with a 20% tolerance, an equivalent series resistance (ESR) of 0.15 ohm, and a maximum ripple current rating of 750 mA. These parameters make it suitable for output filtering on 5 V to 24 V DC-DC converters and power-supply bulk decoupling stages.
How does the 3000-hour lifetime rating at 125 degrees C affect long-term deployment planning?
A 3000-hour lifetime at 125 degrees C means the capacitor meets its rated specifications for at least 3000 hours of continuous operation at the maximum rated temperature. At typical operating temperatures of 85 degrees C, the Arrhenius rule doubles the lifetime for every 10-degree reduction, extending the service life to over 48000 hours, which corresponds to more than 5 years of continuous operation.
What SMD footprint dimensions does the EEE-TC1E471UP use, and how does this compare to similar capacitors?
The EEE-TC1E471UP uses a 10 mm diameter by 10.2 mm height cylindrical SMD footprint. This is a standard D-size aluminum electrolytic can commonly used for 470 µF to 1000 µF SMD capacitors, and the footprint is interchangeable with other manufacturers' D-size SMD electrolytics rated at the same voltage, simplifying second-sourcing.
In what power supply or converter topologies does the EEE-TC1E471UP provide the most benefit?
The EEE-TC1E471UP is most beneficial in buck converter output stages and flyback power supply secondary-side filters operating at 25 V or below. Its 470 µF capacitance and 0.15 ohm ESR reduce output voltage ripple to well under 50 mV in typical 5 A to 10 A load applications, and the 750 mA ripple current rating handles the AC component without derating at the target 125-degree C operating temperature.
