Frequently Asked Questions
What are the capacitance and voltage ratings of the EEE-HD1C221AP, and which power rail applications does this suit?
The EEE-HD1C221AP is rated at 220 µF and 16 V, making it appropriate for bulk decoupling on 5 V, 9 V, and 12 V power rails with adequate voltage derating margin. It is commonly placed at the output of DC-DC converters and LDO regulators to reduce output voltage ripple and provide transient hold-up current during load steps exceeding 500 mA.
How does the Panasonic HD series construction benefit the EEE-HD1C221AP compared to standard aluminum electrolytics?
Panasonic's HD series uses a high-purity aluminum foil and optimized electrolyte to achieve lower ESR and a rated endurance typically exceeding 2000 hours at 105°C compared to standard 1000-hour aluminum electrolytics. This extended lifetime at elevated temperatures suits the EEE-HD1C221AP for use in industrial power supplies, automotive accessories, and computing platforms where reliability over 10+ years at ambient temperatures up to 85°C is required.
What SMD package dimensions and PCB footprint does the EEE-HD1C221AP use?
The EEE-HD1C221AP uses a standard SMD aluminum electrolytic package with a cylindrical can format. Panasonic HD-series SMD capacitors in this 220 µF / 16 V range typically measure 8 mm diameter by 10 mm height, requiring a PCB footprint of approximately 8.3 mm x 8.3 mm with a 5.5 mm land spacing. Designers should verify the exact mechanical dimensions in the Panasonic datasheet before finalizing PCB layout.
When is the EEE-HD1C221AP a better choice than a 220 µF MLCC or polymer capacitor for output filtering?
Aluminum electrolytics like the EEE-HD1C221AP offer much higher capacitance per unit cost compared to 220 µF MLCC or polymer alternatives at 16 V. At 220 µF / 16 V, a polymer capacitor may cost 5 to 10 times more, making the HD-series aluminum electrolytic the preferred choice for cost-sensitive designs where ripple current is below the rated value and operating temperature stays under 85°C.
