Frequently Asked Questions
What are the key electrical ratings of the Panasonic EEE-HD1V220AP capacitor?
The EEE-HD1V220AP is rated at 22 µF capacitance and 35 V maximum working voltage with a ±20% tolerance. These ratings make it suitable for bulk decoupling on power rails up to 35 V and for output filter stages in DC-DC converters where moderate capacitance and voltage headroom are required.
How does the SMD package of the EEE-HD1V220AP simplify PCB assembly compared to through-hole electrolytic capacitors?
The SMD package eliminates through-hole drilling for 22 µF capacitor placements, enabling automated pick-and-place and reflow soldering. This reduces assembly time per board and allows double-sided population. The compact footprint fits within the 35 V, 22 µF specification in a smaller PCB area than equivalent radial through-hole parts typically measuring 5 mm diameter or more.
In which circuit applications is the EEE-HD1V220AP best suited?
This 22 µF, 35 V aluminum electrolytic capacitor is best suited for power supply output filtering, input decoupling on 5 V to 24 V rails, and bulk energy storage in switch-mode power supplies. It is commonly used in industrial control modules, LED driver circuits, and consumer electronics where high capacitance density at low to moderate voltage is required.
When should a designer choose an aluminum electrolytic like the EEE-HD1V220AP over a ceramic capacitor for a 22 µF, 35 V requirement?
At 22 µF and 35 V, multilayer ceramic capacitors (MLCCs) are expensive and physically large, often requiring multiple 10 µF capacitors in parallel. The EEE-HD1V220AP provides 22 µF in a single SMD aluminum electrolytic body at lower cost per unit, making it the practical choice when ripple current is below 100 mA and space efficiency at this capacitance value is prioritized over ceramic's lower ESR.
