Applications
The EEE-HA1V220P is ideal for output filtering and bulk energy storage on 24V and 28V DC power rails in industrial power supplies, set-top boxes, and consumer electronics where a 22µF, 35V SMD capacitor is required. Its low ESR characteristics make it suitable for ripple current filtering at switching regulator outputs operating at frequencies from 50 kHz to 500 kHz. The surface-mount form factor also suits compact DC-DC converter modules, motor driver boards, and automotive infotainment power stages where board space is limited.

Frequently Asked Questions
What is the voltage rating of EEE-HA1V220P and how much derating should engineers apply in a 24V application?
The EEE-HA1V220P is rated at 35V maximum working voltage with 22µF capacitance. Industry standard practice recommends deration to 80% of rated voltage for aluminum electrolytic capacitors, giving a safe working voltage of 28V. In a 24V application this provides a 4V margin above the bus voltage, which is adequate for nominal 24V rails but should account for transients and tolerance in the power supply regulation.
How does the ±20% capacitance tolerance of EEE-HA1V220P affect output ripple in a switching power supply filter design?
The ±20% tolerance means the actual capacitance of EEE-HA1V220P can range from 17.6µF to 26.4µF. In a switching power supply filter designed for 22µF, a worst-case 17.6µF value increases output voltage ripple by approximately 20%, which designers must budget for in the ripple specification. For tight ripple control below 50 mV on a 5V output, paralleling two capacitors or selecting a tighter-tolerance component is advisable.
Which switching frequency range is EEE-HA1V220P suitable for in DC-DC converter output filtering?
Panasonic HA series aluminum electrolytic capacitors including EEE-HA1V220P are suitable for switching frequencies from approximately 50 kHz to 500 kHz in DC-DC converter output filters. At 22µF and 35V, the capacitor provides adequate bulk charge storage and ripple current handling for this frequency range. Above 500 kHz, ceramic capacitors with lower ESR are typically preferred in parallel to handle the high-frequency ripple component more effectively.
What packaging quantity does EEE-HA1V220P ship in and how should it be stored before SMT assembly?
EEE-HA1V220P ships in full reel packaging designed for automated SMT pick-and-place equipment, with a typical reel quantity of 2000 pieces. Aluminum electrolytic capacitors in SMD packaging should be stored in a dry environment below 40°C and 70% relative humidity. While not classified under IPC/JEDEC MSL moisture sensitivity for standard electrolytic types, avoiding moisture ingress before reflow ensures consistent solder joint quality in production.
