 There are a lot of different types of capacitors out there and no shortage of variables to consider when picking one out For example ceramic the very classic and most common capacitor Ceramics are non polarized cheap to produce and available in values from pico ferrats up to about 10 micro ferrats and Occasionally 100 micro ferrats, but they get pretty pricey at that point Ceramics are great for high-frequency filtering and decoupling Electrolytic capacitors can have massive values and they're super cheap They're often polarized, so they must be connected correctly and their capacitance is most effective at signals below 100 kilohertz On top of that preference for low frequency. They can also dry out over time and malfunction Good to know You
