Applications
The EEE-HA1E470WP is used as an output filter capacitor in DC-DC converters, switching power supplies, and point-of-load regulators operating up to 25V where 47 µF bulk capacitance and +105°C thermal stability are needed. It is also common in motor driver boards, industrial control power rails, and consumer electronics power management circuits that require reliable SMD electrolytic capacitors in a compact 6.3 mm footprint. Its 105°C rating suits automotive-adjacent and server environments with elevated ambient temperatures.

Frequently Asked Questions
What are the key electrical ratings of the EEE-HA1E470WP capacitor?
The EEE-HA1E470WP is rated at 47 µF capacitance and 25V DC working voltage with a maximum operating temperature of +105°C. These ratings make it appropriate for bulk filtering on 12V to 24V power rails in industrial and consumer electronics designs where thermal stability is critical.
What SMD package dimensions does the EEE-HA1E470WP use, and does it fit standard SMT reflow assembly?
The capacitor measures 6.3 mm in diameter and 5.4 mm in height with a 6.3 mm lead spacing, conforming to common SMD footprint libraries. It is designed for surface mount reflow soldering at standard profiles up to 260°C peak, making it compatible with automated pick-and-place lines used in high-volume PCB assembly.
How does the +105°C rating of the EEE-HA1E470WP compare to standard 85°C aluminum electrolytic capacitors?
A +105°C rated capacitor typically offers 2 to 4 times longer operational life at the same ambient temperature compared to an 85°C-rated part due to the Arrhenius rule-of-thumb, which halves failure rate for every 10°C reduction in temperature. This makes the EEE-HA1E470WP the preferred choice in server power supplies, industrial motor controllers, and LED drivers where ambient temperatures regularly exceed 70°C.
In which power supply topologies is the EEE-HA1E470WP commonly used as an output filter?
The EEE-HA1E470WP with its 47 µF / 25V rating is commonly placed on the output stage of buck converters, flyback SMPS, and half-bridge DC-DC modules operating in the 5V to 24V output range. It reduces output voltage ripple, typically achieving ripple attenuation below 50 mV peak-to-peak in designs switching at 100 kHz to 500 kHz, and helps maintain load transient stability in point-of-load regulators.
