10、T - Part 5: Transformers and inductors using the series Q of C-cores FOREWORD 1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of the IEC is to promote inte

11、rnational cooperation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, the IEC publishes International Standards. Their preparation is entrusted to technical committees; any IEC National Committee interested in the

12、subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. The IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with condit

13、ions determined by agreement between the two organizations. 2) The formal decisions or agreements of the IEC on technical matters, prepared by technical committees on which all the National Committees having a special interest therein are represented, express, as nearly as possible, an international

14、 consensus of opinion on the subjects dealt with. 3) They have the form of recommendations for international use published in the form of standards, technical reports or guides and they are accepted by the National Committees in that sense. 4) In order to promote international unification, IEC Natio

15、nal Committees undertake to apply IEC International Standards transparently to the maximum extent possible in their national and regional standards. Any divergence between the IEC Standard and the corresponding national or regional standard shall be clearly indicated in the latter. International Sta

16、ndard IEC 852-5 has been prepared by IEC technical committee 51 : Magnetic components and ferrite materials. The text of this standard is based on the following documents: Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above tab

In a form J assembly the reduced height is primarily achieved by having negligible clearance between the terminal board and the remainder of the assembly. This feature restricts the number of terminals which can be fitted and a form J assembly is there- fore used for simpler windings such as chokes.
