What are the key features of EEE-HA1V221UP?
- 220 µF at 35 V with ±20% tolerance for robust bulk energy storage on 24 V and 28 V power rails
- SMD radial package in tape-and-reel for automated high-volume PCB assembly
- High-temperature rated series ensuring stable capacitance across wide thermal operating ranges
- Low-leakage aluminum electrolytic construction minimising standby power loss in idle power supplies
- Panasonic HA series reliability qualification supporting industrial and consumer electronics lifetimes
What is EEE-HA1V221UP used for?
The EEE-HA1V221UP is used as the primary output filter capacitor in 24 V industrial switching power supplies, DC-DC converters, and motor drive bias rails where a 35 V-rated 220 µF SMD bulk capacitor prevents voltage droop during load transients. Its 35 V rating provides a 46% derating margin on 24 V nominal rails, extending service life in industrial PLCs, servo amplifiers, and automation controllers operating in 40°C to 85°C panel enclosures. Consumer electronics designers also specify it for LCD backlight inverter output filtering and set-top box power stages requiring cost-effective SMD bulk capacitance in the 200 µF to 470 µF range.

Frequently Asked Questions
What voltage rating does EEE-HA1V221UP carry, and how much derating margin does it provide on a 24 V industrial rail?
The EEE-HA1V221UP is rated at 35 V, providing approximately 46% voltage derating when used on a 24 V nominal rail. This conservative derating is well within the 80% maximum working voltage guideline for electrolytic capacitors in industrial applications and helps extend capacitor life at elevated temperatures by reducing electrical stress on the oxide film over the 220 µF capacitance value.
How does the 220 µF capacitance of EEE-HA1V221UP help manage load transients in a DC-DC buck converter?
A 220 µF output capacitor on a 24 V buck converter limits output voltage droop during a 2 A step-load transient to approximately 9 mV per microsecond of converter response time, assuming ESR is below 0.1 Ω. This makes EEE-HA1V221UP effective for converters with 5 µs to 20 µs control-loop response times, keeping voltage within ±50 mV of regulation in industrial motor-drive precharge and PLC I/O circuits.
Is EEE-HA1V221UP supplied in tape-and-reel, and what reel size is available for SMT production lines?
Yes, the EEE-HA1V221UP suffix UP designates full tape-and-reel packaging for automated SMD pick-and-place assembly. Panasonic ships HA series SMD electrolytic capacitors on 13-inch (330 mm) reels typically containing 500 to 1000 units per reel, depending on body size. This format integrates directly into standard SMT reflow lines without component handling changes, supporting high-volume SMPS and consumer electronics production.
How does EEE-HA1V221UP compare to a 220 µF MLCC bank for a 35 V rail in terms of board space and cost?
A single 220 µF, 35 V MLCC does not exist at practical cost; achieving 220 µF at 35 V in MLCC technology requires paralleling 10 or more 22 µF, 50 V X7R capacitors in 1210 or larger packages, consuming 5× to 8× the board area of the EEE-HA1V221UP's SMD footprint. The EEE-HA1V221UP provides equivalent bulk capacitance in one component at a fraction of the MLCC bank cost, making it the economical choice for 24 V to 35 V output filter applications above 100 µF.
