IEC 62024-2:2024 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 62024-2:2024 specifies the measuring methods of the rated DC limits for inductors as defined below. 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 125 A, although inductors with rated current greater than 125 A are available that fall within the dimension restrictions of this document (no larger than a 625 mm2 footprint). These inductors are typically used in DC-to-DC converters built on printed circuit boards (PCBs), for electronic 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 (DC). This edition includes the following significant technical changes with respect to the previous edition: a) extension of scope by increase of range of rated current from 22 A to 125 A; b) extension of scope by increase of footprint limitation from 12 mm × 12 mm to 625 mm2; c) addition of upper current limitation for Iclass B, Iclass C and Iclass D board to Table 1; d) revised application examples for Table 1; e) addition of wire size references for current ranges between 22 A <= I <= 125 A to Table 2; f) addition of crimp terminal references to Table 2; g) addition of thermal camera method.
