Applications
The EEE-HA1H101P is well suited for bulk output decoupling on 5 V to 48 V DC/DC converter boards, providing 100 µF of holdup capacitance at up to 50 V to suppress load transients and ripple. It is also used in motor driver power stages, industrial power supplies, and server voltage regulator modules where reliable SMD electrolytic capacitors with low ESR are required. The HA series rating makes it a strong choice for applications demanding long operational life at elevated ambient temperatures.

Frequently Asked Questions
What is the rated capacitance and voltage of the EEE-HA1H101P, and where is it typically placed on a power board?
The EEE-HA1H101P is rated at 100 µF and 50 V. It is typically placed at the output rail of DC/DC converters or linear regulators to provide bulk decoupling and suppress voltage ripple, especially when the load draws transient currents above 1 A. The 50 V rating provides adequate derating margin on 24 V to 36 V industrial power rails.
How does the Panasonic HA series ESR performance benefit switching power supply designs?
HA series capacitors are characterized by lower ESR than standard aluminum electrolytic families at the same capacitance and voltage rating, reducing power dissipation in the capacitor at switching frequencies typically ranging from 20 kHz to 500 kHz. Lower ESR also reduces output voltage ripple amplitude for a given 100 µF capacitance, allowing designers to achieve tighter output regulation without adding additional parallel capacitors.
Which surface-mount package size corresponds to the EEE-HA1H101P, and what reflow conditions does it tolerate?
The EEE-HA1H101P uses a cylindrical SMD case sized for the HA series, typically a 6.3 mm or 8 mm diameter body depending on the height selected. Being a surface-mount aluminum electrolytic, it is compatible with lead-free reflow profiles peaking at 260°C for up to 10 seconds per JEDEC J-STD-020. Panasonic HA series SMD capacitors are also rated for operating temperatures up to 105°C.
When would you choose EEE-HA1H101P over a ceramic multilayer capacitor of similar capacitance?
At 100 µF and 50 V, achieving equivalent capacitance with ceramic MLCC technology would require multiple X5R or X7R capacitors in parallel, significantly increasing BOM count and cost. The EEE-HA1H101P consolidates the full 100 µF bulk storage in a single SMD component, making it the more cost-effective choice for output filter stages on DC/DC converters operating below 500 kHz where ceramic piezoelectric noise is also a concern.
