1>Aluminum electrolytic capacitors are divided into three subfamilies by the type of electrolyte:
· Non-Solid (liquid, wet) aluminum electrolytic capacitors
· Solid manganese dioxide aluminum electrolytic capacitors
· Solid polymer aluminum electrolytic capacitors.
Aluminum electrolytic capacitors with non-solid electrolyte are available in different styles, see pictures above from left to right:
· SMDs (V-chip) for surface mounting on printed circuit boards or substrates
· Radial lead terminals (single ended) for vertical mounting on printed circuit boards
· Radial pin terminals (snap-in) for power applications
