Capacitor Specifications: what they mean

All capacitors have a limited working temperature range whether ceramic capacitors, electrolytic capacitors, tantalum capacitors or whatever type. This specification details the limits within which the capacitor will work satisfactorily and over which it is designed to operate.

Capacitors

Electrolytic and ceramic caps cover about 80% of the capacitor types out there (and supercaps only about 2%, but they''re super!). Another common capacitor type is the film capacitor, which features very low parasitic losses (ESR), making them great for dealing with very high currents. There''s plenty of other less common capacitors.
