What are the key features of EEE-TP1E331AP?
- 330 µF capacitance at 25 V rating provides substantial bulk energy storage for DC-DC converter output filtering
- SMD radial construction enables automated pick-and-place assembly with standard reflow soldering processes
- Panasonic TP series long-life design for extended operational reliability in power supply applications
- Low equivalent series resistance (ESR) reduces output voltage ripple in switching regulator filter stages
- 25 V voltage rating suits 5 V, 12 V, and 15 V rail filtering with adequate derating margin
What is EEE-TP1E331AP used for?
The EEE-TP1E331AP is well-suited as the output bulk capacitor in switched-mode power supplies operating on 5 V to 15 V rails where 330 µF of energy storage is required to suppress switching ripple and handle load transients. It is commonly used in industrial power modules, server voltage regulator modules (VRMs), and consumer electronics motherboards where SMD assembly and a compact footprint are preferred. The 25 V rating provides a comfortable derating margin for 12 V bus filtering applications.

Frequently Asked Questions
What capacitance and voltage rating does the EEE-TP1E331AP provide for power supply filtering?
The Panasonic EEE-TP1E331AP offers 330 µF capacitance with a 25 V voltage rating. This combination is well-suited for filtering the output of 5 V, 12 V, or 15 V DC-DC converters, where the high capacitance reduces output ripple voltage and the 25 V rating provides at least a 2:1 derating margin over the operating voltage, extending the capacitor's service life.
How does low ESR in the EEE-TP1E331AP benefit switching regulator output stages?
Low equivalent series resistance (ESR) in the EEE-TP1E331AP reduces the peak-to-peak ripple voltage at the output of a switching regulator by limiting the voltage drop caused by high-frequency ripple current flowing through the capacitor. At typical switching frequencies of 100 kHz to 500 kHz, a lower ESR value directly translates to cleaner output rails, reducing noise that could affect sensitive analog or digital circuits powered from the same rail.
Why is the SMD package of the EEE-TP1E331AP preferred over through-hole electrolytic capacitors in modern power designs?
SMD mounting of the EEE-TP1E331AP eliminates through-hole drilling costs and enables fully automated reflow soldering, reducing assembly time and per-board cost compared to through-hole electrolytic capacitors. The surface-mount radial case also allows placement on either side of the PCB and reduces board height in slim product enclosures. For 330 µF at 25 V, the SMD form factor is competitive with through-hole alternatives while supporting high-volume automated production lines.
In which industrial or computing applications does the EEE-TP1E331AP 330 µF, 25 V capacitor provide the most value?
The EEE-TP1E331AP provides the most value in server voltage regulator modules (VRMs) supplying CPU and memory rails at 1.8 V to 5 V, industrial motor drive control boards requiring bulk capacitance on 12 V or 24 V logic supply rails, and point-of-load converters in network switches where 330 µF of output capacitance stabilizes voltage during rapid load steps of 5 A or more.
