capacitor
For this reason capacitor manufactures offer electrolytics in both tall and skinny, as well as short and fat styles. Most designs make use of some compromise between too much height or too much width, then they chose parts that fit that style. This is where the compactness of todays capacitors pay off with smaller foot-prints on the board.

6 FAQs about [Relationship between capacitor model and size]
How should a capacitor be sized?
When sizing a capacitor, always choose one with a voltage rating higher than the maximum voltage in your circuit to prevent breakdown and damage. The capacitance value, measured in farads (F), indicates the amount of charge a capacitor can store for a given voltage.
What factors affect a capacitor's capacitance?
Capacitor dimensions, such as plate area and plate separation, can affect a capacitor's capacitance. Increasing plate area increases capacitance, and decreasing plate separation decreases capacitance. Factors such as dielectric constant and temperature can also affect capacitance.
