Aluminium Electrolytic Capacitors
Exxelia aluminum electrolytic capacitors deliver not only high capacitance values (up to 2.2F) and extended service life but also thrive under extreme temperatures and are available as catalog
This article describes aluminum electrolytic capacitors types, features, characteristics and behaviour. The primary strength of aluminum electrolytic capacitors is their ability to provide a large capacitance value in a small package, and do so for a relatively low cost.
This guide covers the application of polar, non-solid aluminum electrolytic capacitors, which are those aluminum electrolytic capacitors featuring a wet, aqueous electrolyte with separator membranes such as cellulosic papers between two aluminum foils.
Aluminum electrolytic capacitors are generally divided into two basic reliability categories: capacitors for high-reliability applications and capacitors for general-purpose applications. This differentiation has also been adopted in the relevant IEC standards.
The international standard for aluminum electrolytic capacitors is IEC 60384-4. The sectional specification mentioned above is complemented by a set of detail specifications that applies to specific design types (e.g. electrolytic capacitors with axial wire leads).
