Ferrite cores - Dimensions Part 13: PQ-cores for use in power supply applications
|Publication Date:||1 July 2016|
|ICS Code (Magnetic components):||29.100.10|
This part of IEC 62317 specifies the dimensions that are of importance for mechanical interchangeability for a preferred range of PQ-cores and low-profile PQI-cores made of ferrite, and the locations of their terminal pins on a 2,54 mm printed wiring grid in relation to the base outlines of the cores.
The selection of core sizes for this standard is based on the philosophy of including those sizes which are industrial standards, either by inclusion in a national standard, or by broadbased use in industry.
NOTE See IEC 62317-1 for more detail concerning the philosophy of selecting core sizes to be included.
The general considerations that the design of this range of cores is based upon are given in Annex A.
