What are the key features of EEE-TC1A331P?
- 330 µF capacitance at 10 V rating provides high bulk energy storage for low-voltage power rail filtering and hold-up applications
- Surface-mount 10 mm x 10.2 mm package enables automated PCB assembly via standard SMT reflow without through-hole drilling
- Panasonic TC series electrolytic construction provides low equivalent series resistance (ESR) for improved switching power supply ripple performance
- Polarized aluminum electrolytic construction offers high capacitance-to-volume ratio suitable for space-constrained DC-DC converter output stages
What is EEE-TC1A331P used for?
The EEE-TC1A331P is used as an output bulk capacitor in 5 V to 10 V DC-DC converter modules, USB power bank circuits, and low-voltage linear regulator outputs where 330 µF of capacitance reduces voltage ripple and improves transient load response. Its SMT construction makes it suitable for dense PCB layouts in consumer electronics, portable devices, and industrial IoT power modules where board space is limited. The 10 V voltage rating provides a 2x safety margin over typical 5 V rails, extending service life in high-ripple applications such as motor driver supply filtering and LED driver power stages.

Frequently Asked Questions
What is the capacitance and voltage rating of the EEE-TC1A331P and how does it fit a 5 V rail decoupling application?
The EEE-TC1A331P is rated at 330 µF and 10 V, giving a 2x derating margin on a 5 V supply rail. At 330 µF, it can absorb a 1 A load transient and limit the 5 V rail droop to approximately 3 mV per µs, making it effective as a bulk output capacitor for DC-DC converters and linear regulators.
How does the surface-mount package of the EEE-TC1A331P compare in footprint to a through-hole electrolytic of the same value?
The EEE-TC1A331P occupies a 10 mm diameter x 10.2 mm height SMT footprint, which is significantly more compact than an equivalent 330 µF, 10 V radial through-hole capacitor that typically measures 10 mm diameter x 12.5 mm height and requires drilled PCB holes. The SMT form factor enables placement in dense automated reflow assembly lines with component heights below 11 mm.
In which power supply topologies does the 330 µF capacitance of the EEE-TC1A331P provide the greatest benefit?
A 330 µF output capacitor provides maximum benefit in switched-mode power supply (SMPS) designs operating at frequencies below 100 kHz, where high capacitance reduces output voltage ripple below 50 mV peak-to-peak at load currents up to 2 A. It is particularly effective in buck converters, USB charger outputs, and battery backup circuits requiring stable 5 V to 10 V regulation.
What operating temperature range should designers assume for the EEE-TC1A331P in a thermally demanding environment?
Panasonic TC series aluminum electrolytic capacitors are typically rated for operation from -40°C to +105°C, which covers industrial temperature environments. At the upper end of 105°C ambient, the capacitor's rated lifetime is typically 1000 hours to 2000 hours, so designers should derate operating temperature by 10°C to 20°C in continuously high-temperature power supply enclosures to extend field life beyond 5 years.
