IEC TR 63362-1:2022(E) establishes guidelines for the application and use of aluminium electrolytic capacitors in electronic equipment.
The information given in this document applies to capacitors with non-solid electrolyte but can, in its appropriate clauses, apply to capacitors with solid electrolyte as well.
Electrolytic capacitors in general – and aluminium electrolytic capacitors in particular – are an exception in the capacitor field because of the components’ close interaction of physics and chemistry. Therefore, aluminium electrolytic capacitors show, in various aspects, a technical behaviour unaccustomed to the user. That could easily lead to misapplications and even to endangering of persons and goods. The aim of this document is to minimize these risks by providing detailed information on the specific peculiarities of the component.
This first edition cancels and replaces CLC/TR 50454 published in 2008. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:  
Complete technical revision, details of cleaning processes and failure modes added.
Inclusion of parts of JEITA RCR 2367D.

This part of IEC 60384 applies to fixed aluminium electrolytic surface mount capacitors with conductive polymer solid electrolyte, primarily intended for DC applications for use in electronic equipment.
Fixed aluminium electrolytic surface mount capacitors with solid (MnO2) are not included but are covered by IEC 60384-18.
These capacitors are primarily intended for use in electronic equipment to be mounted directly on substrates for hybrid circuits or to printed boards.
Capacitors for special-purpose applications may need additional requirements.
The object of this document is to prescribe preferred ratings and characteristics and to select from IEC 60384-1:2016, the appropriate quality assessment procedures, tests and measuring methods and to give general performance requirements for this type of capacitor. Test severities and requirements prescribed in detail specifications referring to this sectional specification shall be of equal or higher performance level, because lower performance levels are not permitted.
