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.
