Foreword

GB/T 28864 "ferrite core definitions of the terms" is divided into three parts. --- Part 1. terms of physical defects; --- Part 2. Dimensions; --- Part 3. Transformers and inductors factory core catalog guidance concerning ferrite material information. This section GB/T 28864 Part 2. This section drafted in accordance with GB/T 1.1-2009 given rules. This section uses the translation method is equivalent to using IEC 60401-2.2003 "ferrite core Definition - Part 2. Dimensions." For ease of use, this part of IEC 60401-2.2003 made the following editorial changes. a) "this International Standard" be replaced by "this section"; b) Remove the preface to international standards. This part is proposed by the Ministry of Industry and Information Technology of the People's Republic of China. This part of the National Magnetic components and ferrite materials Standardization Technical Committee (SAC/TC89) centralized. This section drafted by. China Electronics Technology Group Corporation ninth Institute. The main drafters of this section. Hu Bin. Ferrite core Definition Part 2. Dimensions

1 Scope

This section GB/T 28864 given on ferrite (magnetic oxide) form the main core feature size identification code set Righteous way. The purpose of this section is to enable manufacturers, standards writers and users uniform size in the design, form and catalog Callout.

2 Basic Principles

Dimensions are indicated in uppercase letters of the alphabet. Each shape of the ferrite core size only by a letter. Paired core 2B and 2D represent letters, such as EP-shaped, PQ-shaped pot-shaped cores and RM. Method 3 Dimensions Main dimensions ferrite core shapes alphabetically with uppercase English letters, are shown in Table 1 and Table 2. Remaining secondary core Size standard writers should own label. Table 1 toroidal core Dimension Meaning letter size A ring-shaped core outside diameter B ring core inner diameter C ring core height Table 2 ferrite core dimension Meaning letter size A total length of the rear wall or the core diameter B core outer leg length or height C core width D inner core leg length or depth E bobbin core width or pitch F center column thickness or diameter G line aperture or groove width H aperture center column J RM core width parallel sides ......
