Applications
EEE-HBC221UAP is well-suited as an output filter capacitor in DC-DC converters and switch-mode power supplies where 220 µF capacitance at 16 V is needed to reduce output voltage ripple. The low-ESR HB series construction makes it effective in CPU voltage regulator modules (VRMs) and point-of-load converters on motherboards and server power stages. It is also applicable in audio amplifier power rails and industrial control board decoupling networks that require stable bulk capacitance.

Frequently Asked Questions
What are the key electrical ratings of the EEE-HBC221UAP capacitor for switching power supply design?
The EEE-HBC221UAP is rated at 220 µF capacitance with a 16 V working voltage, making it suitable as an output bulk capacitor in 12 V to 15 V power rails. Its HB series low-ESR characteristic reduces output ripple voltage, and the 105°C maximum temperature rating ensures reliable operation in high-density power stages where ambient temperatures often exceed 85°C.
How does EEE-HBC221UAP compare to standard electrolytic capacitors in terms of ESR performance?
The HB series aluminum electrolytic capacitors from Panasonic, including EEE-HBC221UAP, achieve lower equivalent series resistance (ESR) compared to general-purpose electrolytic types rated at the same 220 µF and 16 V. Lower ESR directly reduces I²R heating in the capacitor, allowing designers to use fewer capacitors in parallel to meet ripple current specifications in 5 A to 20 A switching converter outputs.
Which PCB footprint and case size does EEE-HBC221UAP use, and how does it affect board layout?
EEE-HBC221UAP uses a surface-mount (SMD) package with standard radial-style SMD termination compatible with automated placement on standard 0.5 mm to 1.0 mm PCB pad pitches. The compact case size minimizes board area compared to through-hole electrolytic alternatives rated at 220 µF, enabling tight component spacing in server motherboards and compact DC-DC converter modules.
In what application scenarios is a 220 µF, 16 V capacitor like EEE-HBC221UAP typically the optimal choice?
A 220 µF, 16 V SMD electrolytic capacitor like the EEE-HBC221UAP is optimal for output filtering in non-isolated buck converters with 12 V input and 5 V output at load currents of 3 A to 10 A, where the combination of bulk capacitance and low ESR is needed to maintain output ripple below 50 mV. It is also used in industrial PLCs and embedded computing boards requiring board-level bulk energy storage at 12 V rails.
