What are the key features of EEE-HD1A331AP?
- 330 µF capacitance at 10 V in an SMD aluminum electrolytic form factor, delivering large bulk energy storage for power rail decoupling and output filtering in DC-DC converters
- HD series low-ESR construction minimizes power loss and voltage ripple at switching frequencies, improving efficiency in compact power management designs
- 105°C maximum operating temperature rating supports continuous use in elevated-temperature environments such as power supply modules and motor drive boards
What is EEE-HD1A331AP used for?
EEE-HD1A331AP is well suited for output bulk capacitance in low-voltage DC-DC converters, LDO regulators, and point-of-load power modules operating on 5 V or lower rails where 330 µF of charge reservoir is needed. It is also used in audio amplifier power supply filtering, motor driver decoupling, and consumer electronics power stages where high capacitance density in a small SMD footprint reduces PCB real estate.

Frequently Asked Questions
What capacitance and voltage rating does EEE-HD1A331AP provide, and on which power rails can it be used?
EEE-HD1A331AP provides 330 µF of capacitance at a 10 V rating. It is suitable for decoupling and bulk energy storage on 3.3 V, 5 V, and other rails below 10 V working voltage. With 330 µF, it provides ample charge reservoir for transient load steps in CPU core supplies, DDR memory rails, and low-voltage motor driver power stages.
How does the HD series designation benefit EEE-HD1A331AP in switching power supply designs?
The HD series from Panasonic is characterized by lower ESR compared to standard aluminum electrolytic capacitors. Lower ESR reduces resistive power loss, decreases output voltage ripple at switching frequencies typically between 100 kHz and 1 MHz, and generates less self-heating. This makes EEE-HD1A331AP a better choice than standard electrolytic capacitors for output filtering in DC-DC converters operating in compact, thermally constrained enclosures.
What maximum operating temperature does EEE-HD1A331AP support, and how does this affect component selection in industrial designs?
EEE-HD1A331AP is rated for a maximum operating temperature of 105°C. This rating accommodates the elevated ambient temperatures found in industrial power supplies, embedded computing modules, and motor drive boards mounted inside sealed enclosures. Designers who need to meet a 10-year or 50,000-hour service life at reduced operating temperatures can derate from the 105°C ceiling, extending capacitor lifespan significantly.
