What are the key features of EEE-1EA220WAR?
- 22 µF capacitance at 25 V rated voltage in a compact SMD package for space-efficient power supply filtering and decoupling
- Panasonic VS series low-ESR design supports stable voltage regulation in DC-DC converters and linear regulators operating up to 105°C
- Surface-mount aluminum electrolytic construction enables automated reflow assembly with high volumetric efficiency versus ceramic alternatives at this capacitance value
What is EEE-1EA220WAR used for?
The EEE-1EA220WAR is widely used as an output bulk capacitor in DC-DC converter designs, where its 22 µF capacitance and low ESR reduce output voltage ripple at switching frequencies from tens to hundreds of kHz. It also serves as a bypass and filtering capacitor on 5 V and 12 V power rails in consumer electronics, set-top boxes, and industrial control boards. Its SMD form factor simplifies high-volume automated assembly while the 25 V rating provides adequate margin for 5 V rail applications.

Frequently Asked Questions
What capacitance and voltage rating does the EEE-1EA220WAR carry, and which power rail voltages does it suit?
The EEE-1EA220WAR is rated at 22 µF and 25 V. This rating suits decoupling and filtering on 5 V, 9 V, and 12 V power rails, providing a comfortable 2x to 5x derating factor that extends component life and meets reliability targets in consumer electronics, set-top boxes, and industrial control boards operating over a wide temperature range.
How does the Panasonic VS series EEE-1EA220WAR perform in switching power supply output filter applications?
In DC-DC converter output filters, the EEE-1EA220WAR's low ESR characteristic reduces output ripple voltage, typically keeping peak-to-peak ripple below a few tens of millivolts at switching frequencies of 100 kHz to 500 kHz for moderate load currents. Combined with the 22 µF bulk capacitance, it supports transient load steps of several hundred milliamps without exceeding acceptable output voltage deviations in typical 5 V converter designs.
What SMD package size does the EEE-1EA220WAR use, and how does it compare to a 22 µF MLCC in terms of cost and board footprint?
The EEE-1EA220WAR uses a cylindrical SMD aluminum electrolytic package that is generally larger than a 22 µF 0805 or 1210 MLCC, but it is significantly lower in unit cost per microfarad at the 25 V rating. While MLCCs offer lower ESR and smaller footprint at lower capacitance values, the aluminum electrolytic remains the cost-effective choice when 22 µF at 25 V is needed in price-sensitive consumer or industrial products.
