IEC 60384-24-2015 pdf download.Fixed capacitors for use in electronic equipment – Part 24: Sectional specification – Fixed tantalum electrolytic surface mount capacitors with conductive polymer solid electrolyte.
This part of IEC 60384 applies to fixed tantalum electrolytic surface mount capacitors with conductive polymer solid electrolyte primarily intended for d.c. applications for use in electronic equipment.
Fixed tantalum electrolytic surface mount capacitors with solid (MnO 2 ) electrolyte are not included but are covered by IEC 60384-3.
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.
1 .2 Object
The object of this standard is to prescribe preferred ratings and characteristics and to select from IEC 60384-1 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.
1 .3 Normative references
The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

1 .4 Information to be given in a detail specification
1 .4.1 General
Detail specifications shall be derived from the blank detail specification.
Detail specifications shall not specify requirements inferior to those of the generic, sectional or blank detail specification. When more severe requirements are included, they shall be listed in 1 .9 of the detail specification and indicated in the test schedules, for example, by an asterisk.
The information given in 1 .4.2 may, for convenience, be presented in tabular form.
The following information shall be given in each detail specification and the values quoted shall preferably be selected from those given in the appropriate clause of this sectional specification.
1 .4.2 Outline drawing and dimensions
There shall be an illustration of the capacitors as an aid to easy recognition and for comparison of the capacitors with others.
Dimensions and their associated tolerances, which affect interchangeability and mounting, shall be given in the detail specification. All dimensions shall preferably be stated in millimetres; however, when the original dimensions are given in inches, the converted metric dimensions in millimetres shall be added.
The numerical values of the body shall be given as follows:
– for general: the width, length and height.
The numerical values of the terminals shall be given as follows:
– for terminals: the width, length and spacing.
When the configuration is other than described above, the detail specification shall state such dimensional information as will adequately describe the capacitor.
1 .4.3 Mounting
The method of mounting for tests and measurements are given in 4.3. The detail specification shall specify the methods of mounting for normal use.
1 .4.4 Ratings and characteristics
1 .4.4.1 General
The ratings and characteristics shall be given in accordance with the relevant clauses of this specification, together with the following.
1 .4.4.2 Nominal capacitance range See 2.2.1 .
When products approved to the detail specification have different nominal capacitance ranges, the following statement should be added:
“The nominal capacitance range available in each voltage range is given in the register of approvals, available for example on the IECQ on-line certificate system website www.iecq.org”.
1 .4.4.3 Particular characteristics
Additional characteristics may be listed when they are considered necessary to specify adequately the component for design and application purposes.IEC 60384-24 pdf download.
