Introduction

With the continuous development of electronics and communication technology, the application of surface-mounted fixed inductors has been very extensive. Of electronic and communication equipment High-density installation places higher requirements on the miniaturization, electrical and mechanical properties of inductors. In order to facilitate production and trade, it is necessary to standardize the table Terminology, standard values, dimensions, mechanical properties and electrical properties of surface-mounted fixed inductors. GB/T 40852 "High-frequency inductive components non-electrical special Sex and its measurement method is composed of two parts. ---Part 1.Surface mount fixed inductors for electronic and communication equipment. Established the requirements and description of surface mount fixed inductors Terminology, recommended standard values and dimensions. ---Part 2.Measurement methods of non-electrical characteristics. Specifies the measurement method of non-electrical characteristics of surface-mounted fixed inductors. GB/T 40852 "Non-electrical characteristics of high-frequency inductive components and their measurement methods" aims to guide high-frequency inductive component companies to organize production and Foreign trade, improve the technical level of the inductor industry. Non-electrical characteristics of high-frequency inductive components and their measurement methods Part 1.For electronic and communication equipment Surface mount fixed inductor

1 Scope

This document applies to surface mount fixed inductors and ferrite beads. When the specifications in this document are inconsistent with the detailed product specifications, the detailed product specifications should prevail. The purpose of this document is to establish the requirements, description terms, recommended standard values and dimensions for surface-mounted fixed inductors, which can be used as surface-mounted Guidelines for the use of fixed inductors.

2 Normative references

The content of the following documents constitutes an indispensable clause of this document through normative references in the text. Among them, dated quotations Only the version corresponding to the date is applicable to this document; for undated reference documents, the latest version (including all amendments) is applicable to This document. IEC 61605.20161) Fixed inductor identification code for electronic and communication equipment (Fixedinductorsforuseinelectronic andtelecommunicationequipment-Markingcodes)

3 Terms and definitions

There are no terms and definitions that need to be defined in this document.

4 Graphic symbols and naming

Surface-mounted fixed inductors are named using a combination code of 12 numbers and letters. The naming of ferrite beads should be in the detailed specification Regulation. □ □ □ □ □ □ □ □ □ □ □ □ a) b) c) d) e) a) Inductor type. Surface-mounted fixed inductors should use the three-letter code "LCL". b) Dimensions. The external dimensions of surface mount inductors should be represented by four numbers, each of L and W (or H) has two dimensions. A number with a specific meaning. As shown in Figure 1, for shape D, the first two numbers indicate the long side size L, and the last two numbers indicate the short Side size W; For shape K, the first two numbers indicate the shape size L, and the last two numbers indicate the height size H. c) External shape. The external shape of the surface-mounted fixed inductor is represented by the single letter code given in Figure 1. The shape code of the inductor is classified according to its external shape. 1) IEC 61605.2005 has been replaced by IEC 61605.2016, and the content cited in this document still applies. ......
