•
1 like•1,107 views
This document discusses different types of capacitors that are commonly used for audio purposes. It lists 14 types of capacitors including electrolytic aluminum, ceramic disc, metalized polyester film, multilayer metalized polyester film, resin dipped film, radial and non-polarized electrolytic, tantalum, metalized polypropylene film, tantalum bead, polystyrene film, multilayer polypropylene film, audio grade axial polypropylene, and high temp axial electrolyte capacitors. For each type, it provides a brief description of their common audio applications and includes links to sources where the capacitors can be purchased.
