Applications
The EEE-HB1C220AR is well-suited for output ripple filtering in 5 V and 12 V switching power supplies, LDO regulator bulk bypass, and energy storage in embedded systems and consumer electronics. The 22 µF, 16 V rating provides adequate bulk capacitance for microcontroller VCC decoupling and gate driver bypass in motor control boards. Its compact SMD form factor is appropriate for notebook computers, IoT modules, LED drivers, and industrial automation circuits where board space is limited.

Frequently Asked Questions
What are the capacitance and voltage ratings of EEE-HB1C220AR and how does it fit a 5 V supply filter?
EEE-HB1C220AR is rated at 22 µF capacitance and 16 V maximum working voltage. On a 5 V power rail, the 16 V rating provides a comfortable 3.2× derating factor, and the 22 µF bulk capacitance effectively suppresses output voltage ripple from switching regulators operating at frequencies above 50 kHz when combined with a 100 nF ceramic bypass capacitor.
What does the HB series designation indicate about EEE-HB1C220AR's temperature and lifetime rating?
The HB series from Panasonic indicates a high-reliability, long-life aluminum electrolytic rated at 105°C, typically with an endurance of 2000 hours or more at maximum rated temperature. Compared to standard 85°C series capacitors, HB-rated components exhibit significantly longer service life at lower operating temperatures, making EEE-HB1C220AR suitable for industrial and commercial electronics with 5 to 10 year operational requirements.
How does EEE-HB1C220AR perform in switching power supply output filtering at 100 kHz?
At 100 kHz, EEE-HB1C220AR exhibits reduced ESR compared to standard aluminum electrolytics, allowing effective ripple current attenuation in switching converter outputs. In a typical 12 V to 5 V buck converter with 1 A load, a single 22 µF output capacitor limits peak-to-peak voltage ripple to approximately 10–30 mV depending on converter inductance and switching frequency.
Is EEE-HB1C220AR compatible with automated SMT reflow soldering, and what package dimensions does it use?
Yes. EEE-HB1C220AR is in a standard SMD aluminum electrolytic package with surface-mount leads, fully compatible with automated pick-and-place equipment and reflow soldering up to 260°C per J-STD-020. The SMD package is typically in the 4 mm × 5.4 mm or similar cylindrical SMD footprint standard for 22 µF aluminum electrolytic capacitors in this voltage class.
When should EEE-HB1C220AR be selected over a 22 µF tantalum capacitor for a 16 V decoupling application?
EEE-HB1C220AR is preferred over tantalum when cost is a priority, as aluminum electrolytics are significantly cheaper per µF at comparable voltage ratings. Tantalum capacitors offer lower ESR and a smaller package for the same capacitance at 16 V, but tantalum has a known failure mode under surge conditions above rated voltage, while the aluminum EEE-HB1C220AR is more tolerant of short-duration overvoltage transients in typical 5 V and 12 V supply applications.
