Applications
The Panasonic EEE-HAE100WAR is widely used in portable consumer electronics, IoT modules, and industrial control boards for power supply output filtering and local bypass decoupling on DC rails up to 25 V. Its SMD form factor enables automated PCB assembly and suits compact device designs where through-hole components are not practical. The HA series low-ESR characteristic makes it effective in switching regulator output stages where minimizing output ripple voltage is critical to downstream circuit stability.

Frequently Asked Questions
What capacitance and voltage rating does the Panasonic EEE-HAE100WAR carry, and in which supply rail range can it be used?
The EEE-HAE100WAR is rated at 10 µF capacitance and 25 V maximum working voltage. It is suitable for decoupling and filtering on DC supply rails up to 20 V when a standard 80% voltage derating is applied, covering 3.3 V, 5 V, 12 V, and 15 V logic and power rails commonly found in consumer electronics and industrial embedded systems.
How does the low-ESR characteristic of the HA series benefit switching power supply designs compared to standard electrolytic capacitors?
Low ESR in the Panasonic HA series reduces the resistive voltage drop across the capacitor during high-frequency ripple currents, resulting in lower output voltage ripple and less heat generation within the capacitor. In a typical 500 kHz switching regulator, an HA series capacitor with ESR below 100 milliohms can reduce peak-to-peak output ripple by 30 to 50% compared to standard electrolytic types with ESR above 300 milliohms.
For a 5 V USB power input stage, how many EEE-HAE100WAR units are typically needed at the output of the rectifier or regulator?
For a 5 V regulated USB output stage with a 500 mA load, one to two 10 µF EEE-HAE100WAR capacitors in parallel, totaling 10 to 20 µF at 25 V, are typically sufficient for output filtering at switching frequencies above 200 kHz. Additional 100 nF ceramic bypass capacitors are recommended in parallel to handle high-frequency noise above 10 MHz that exceeds the bandwidth of the electrolytic.
How does the SMD packaging of the EEE-HAE100WAR compare to a radial through-hole electrolytic in terms of PCB area and assembly process?
The EEE-HAE100WAR SMD package occupies a defined land pattern footprint on one side of the PCB without requiring drilled through-holes, reducing board fabrication cost and enabling double-sided automated reflow assembly. SMD electrolytic capacitors typically reduce the PCB footprint area by 20 to 40% compared to equivalent radial leaded parts, and eliminate the separate wave-soldering step needed for through-hole components.
