What are the key features of EEE-1AA221P?
- 220µF capacitance at 10V rated voltage with 20% tolerance for broad design flexibility
- SMD (surface-mount) form factor enabling automated PCB assembly and space-efficient layouts
- Panasonic aluminum electrolytic construction delivering long operational life and stable performance
- Low ESR characteristics suitable for power supply decoupling and bulk energy storage applications
What is EEE-1AA221P used for?
The EEE-1AA221P is widely used in power supply filtering and decoupling circuits on consumer electronics, industrial control boards, and portable devices. Its 220µF capacitance at 10V makes it ideal for smoothing rectified DC outputs and suppressing voltage ripple in low-voltage switching regulators. The SMD package supports high-density PCB designs where through-hole components are not viable.

Frequently Asked Questions
What is the capacitance and voltage rating of the EEE-1AA221P?
The EEE-1AA221P provides 220µF of capacitance rated at 10V with a ±20% tolerance. This combination suits low-voltage power rails where bulk energy storage or ripple filtering across a 10V bus is required in compact SMD form factor.
In which power supply topologies is EEE-1AA221P most effective?
This capacitor is effective in linear and switching power supply output stages operating at or below 10V, including 5V and 3.3V rails. The 220µF value provides sufficient charge reservoir to reduce output ripple below acceptable limits in many Buck converter designs running at 100 kHz to 500 kHz switching frequencies.
How does the SMD package of EEE-1AA221P benefit automated PCB assembly?
The SMD package allows pick-and-place automated assembly, reducing per-unit labor costs compared to through-hole alternatives. Components can be placed at densities up to several hundred parts per board in a single reflow pass, and the footprint occupies less than 10 mm² of board area in typical configurations.
When should a designer choose EEE-1AA221P over a ceramic capacitor of similar capacitance?
Aluminum electrolytic capacitors like EEE-1AA221P deliver 220µF at low cost per µF compared to ceramic alternatives, which rarely exceed 100µF at 10V in standard sizes. The electrolytic construction is preferred when bulk storage matters more than ultra-low ESR, and when board space allows for an SMD electrolytic footprint rather than multiple ceramic capacitors in parallel.
