Sensory.

The technical differences between this document and IEC 62024-1.2017 and the reasons are as follows.

---Added the switching method (see 6.1.2.2), the forward and reverse current method (see 6.1.2.3), and the Kelvin double bridge method (see 6.2.2). These

The method has been adopted on a large scale in the industry;

--- Modify Figure 10, delete unnecessary graphical parameters RV.

The following editorial changes have been made to this document.

---Change the vector voltmeter "EV" to "U", and the vector voltage "E" to "U";

---According to my country's drawing standards, the third view in the original international standard is changed to the first angle view for drawing (see Figure 2, Figure 3,

Figure 6, Figure 8);

--- Added the explanation of the meaning of the symbols in formula (13), and gave the unit.

Introduction

With the continuous development of electronic technology and communication technology, high-frequency inductors have been widely used, and their electrical characteristics and measurement methods have also become popular.

Use it all over. The high frequency, low power consumption, multi-function, light weight and thin profile of electronic and communication equipment put forward higher requirements for inductors, in addition to

In addition to the material properties and processing capabilities of inductors, it also includes testing and measurement methods. GB/T 40853 "Electrical characteristics of high-frequency inductive components and their

"Measurement Methods" is the standard for standardizing electrical characteristics and measurement methods. GB/T 40853 consists of two parts.

---Part 1.Nanohenry chip inductors. Specifies the electrical characteristics of high-frequency (above 100kHz) nanohenry chip inductive components

(Inductance, quality factor, impedance, resonance frequency, DC resistance, etc.) and its measurement methods.

---Part 2.Inductor rated current for DC-DC converters. Specifies the amount of high-frequency inductive components based on their own temperature rise

Constant current and rated current based on the rate of change of inductance value and its measurement method.

GB/T 40853 "Electrical characteristics of high-frequency inductive components and their measurement methods" aims to guide high-frequency inductive component enterprises to organize production and external

Trade to improve the technical level of the inductor industry.
