Frequently Asked Questions
What are the rated voltage and capacitance of the EEA-GA1A220B, and in which circuit topologies is it commonly used?
The EEA-GA1A220B is rated at 10 V working voltage with 22 µF capacitance. It is commonly used as an output bulk decoupling capacitor in low-voltage DC-DC converters, as a bypass capacitor on 5 V and 3.3 V supply rails, and as a coupling or filter element in audio circuits. The 22 µF value provides adequate energy storage for transient load response in compact low-power designs.
What are the physical dimensions and lead spacing of the EEA-GA1A220B, and how do these affect PCB layout?
The EEA-GA1A220B has a 4 mm diameter cylindrical body, a 7 mm height, and a 5.0 mm lead pitch between the two radial through-hole leads. PCB designers should drill 0.6 mm or larger holes at a 5.0 mm centre-to-centre spacing. The compact 4x7 mm body allows dense placement on crowded boards compared to larger 6.3 mm or 8 mm diameter alternatives of the same 22 µF value.
What does the ammo-crimp packaging of the EEA-GA1A220B mean for manufacturing, and which assembly process does it support?
Ammo-crimp is a tape format for radial-leaded components where capacitors are held in a paper or plastic carrier strip at fixed intervals. This allows the EEA-GA1A220B to be fed into automated radial-lead insertion (RLI) machines, enabling high-speed through-hole PCB assembly. After insertion, the leads are clinched and wave-soldered, making ammo-crimp the preferred packaging for high-volume consumer electronics and industrial PCB production lines.
When should an engineer select the EEA-GA1A220B over a 22 µF 10 V MLCC for a power supply filter design?
The EEA-GA1A220B is preferred over a 22 µF 10 V MLCC in cost-sensitive designs where through-hole assembly is already planned and the lower cost-per-microfarad of aluminum electrolytic capacitors is important. Electrolytic capacitors also handle higher ripple current than equivalently rated MLCCs at 22 µF, making the EEA-GA1A220B a better fit for output filter stages carrying tens of milliamps of ripple current on a 10 V rail. MLCCs are preferred when smaller size or surface-mount assembly is required.
