Fig. 1 — Power Transformer, Full-Wave Rectifier, Filter Capacitors . All power supply filter caps are "electrolytics". Electrolytic caps contain an electrolyte (an ionic conducting paste) that causes an oxide coating to form on the positive plate of the capacitor. The thin coating serves as the insulating layer between the two capacitor plates.

This is often very true of coupling capacitors. Power supply capacitors are generally electrolytic, though they can be replaced by film capacitors. Electrolytic capacitors are polarized so it''s important to orient them properly according to the schematic. Coupling capacitors are always film caps and these are non-polar, or bi-directional.

The capacitor will probably be a size 1210 and 25V. Every manufacturer is different and you need to carefully read the datasheet. If you choose a capacitor of size 0805 and voltage of 6.3V, you''ll be unlikely to achieve anywhere near 22uF of capacitance. If you''re height constrained, use a number of smaller capacitors.
PLCC component – Coupling Capacitor. Coupling capacitor connects the carrier equipment to the transmission line. The coupling capacitor''s capacitance is of such a value that it offers low impedance to carrier frequency (1/ωC) but high impedance to power frequency (50 Hz). For example 2000pF capacitor offers 1.5MΩ to 50Hz but 150Ω to 500kHz.

This doesn''t mean that capacitor coupling is not used though, and there are a surprisingly large number of amplifiers that still use an output capacitor. These are primarily low-power designs, and they are used in many consumer products because they are cheaper to build than a dual supply. Figure 5.2 - Voltage & Current For Symmetrical ±8V Output
Yes "decoupling" and "bypass" capacitors are the same thing. Ideally the power supply to a chip would have a zero impedance at all frequencies. If the power supply has a finite impedance it will act as an unwanted coupling path. The higher the impedance the stronger this unwanted coupling path. The unwanted coupling path can have various effects.
