The situation of China inductor market this year

February 27 , 2021

1. Overview of inductors

Inductors are electronic components that can convert electrical energy into magnetic energy and store it. The structure of the inductor is similar to that of a transformer, but it has only one winding. The inductor has a certain inductance, it only blocks the change in the amount of current. If the inductor has no current through it, it will try to block the current through it when the power circuit is connected; if the inductor is through the current, it will try to maintain the current when the power circuit is disconnected. will not change. Inductors are also called chokes, series reactors, and dynamic reactors. Inductors are generally composed of skeletons, windings, shields, packaging materials, magnetic cores or iron cores.

Inductors can be divided into frequency radiation inductors and output power inductors according to their different functions; they can be divided into winding inductors, laminated inductors, and plastic film inductors according to different processing techniques; they can be divided into magnetic inductors and non-magnetic inductors according to different raw materials.

2. Market scale of inductors

The world's electronic information industry is developing rapidly. Inductors, one of the indispensable basic electronic components in the industrial development plan, continue to be worn out and innovated, and they will be rapidly updated in both application and product characteristics and quality. The global inductor market in 2019 was 48.64 billion yuan, a year-on-year increase of 1% from 48.16 billion yuan in 2018; it is estimated that in 2020, due to the harm of the new crown pneumonia epidemic worldwide, the inductor market size will drop to 44.54 billion yuan .

With the rapid replacement of China's communication technology and the large-scale construction of related industries such as the Internet of Things and new smart cities, the scale of China's inductor market has developed rapidly. In 2019, the size of China's inductor market was about 16.04 billion yuan, compared with 14.19 billion in 2018 Yuan Renminbi increased by 13% year-on-year.

According to the data of the "Prediction Report on China's Inductor Industry Development Trends and Competitive Patterns 2021-2027" released by Zhiyan Consulting, the operating income of China's inductors has gradually increased from 2014 to 2019, and the operating income of inductors has increased from 8.136 billion yuan in 2014. The renminbi rose to 17.045 billion yuan in 2019. It is estimated that the demand for the inductor sales market will increase, and the Chinese sales market will be broader.

3. Import and export trade of inductors

The overall supply and demand situation of China's inductor field is in short supply, and the external dependence is very large. In 2019, the total number of China's inductor exports was 73.378 billion, and the total number of imports was as high as 178.983 billion. The total number of inductor imports was 2.4 times the total number of exports.

In 2018, China’s inductor export quota was 2.901 billion U.S. dollars, and its import quota was 2.719 billion U.S. dollars; in 2019, China’s inductor export quota was 2.898 billion U.S. dollars, and its import quota was 2.752 billion U.S. dollars.

Fourth, the development trend of inductors

As the volume of electronic components in the world is getting smaller and smaller, the relative density of power supply circuits is getting higher and higher, and the transmission rate is getting faster and faster. China's inductors must follow the development of global electronic components, and then they can keep up with the development of global electronic components. Therefore, in the future, inductors must be oriented towards miniaturization, high frequency, high precision, and integrated development.
