1 Scope
This part of IEC 62024 specifies the measuring methods of the rated direct current limits for small inductors.
Standardized measuring methods for the determination of ratings enable users to accurately
compare the current ratings given in various manufacturers’ data books.
This document is applicable to leaded and surface mount inductors with dimensions
according to IEC 62025‑1 and generally with rated current less than 22 A, although inductors with rated current
greater than 22 A are available that fall within the dimension restrictions of this
document (no larger than a 12 mm × 12 mm footprint approximately). These inductors
are typically used in DC-to-DC converters built on PCBs, for electric and telecommunication
equipment, and small size switching power supply units.
The measuring methods are defined by the saturation and temperature rise limitations
induced solely by direct current.
