Analysis on the development of domestic and foreign passive components industry predicts small devices and large uses, and passive components are ushering in a price increase

Passive components, also known as passive components, refer to circuit components that do not affect the basic characteristics of the signal and only allow the signal to pass through without changing it.The most common ones include resistors, capacitors, inductors, ceramic oscillators, crystal oscillators, transformers, etc.From the perspective of working characteristics, passive components have the characteristics of not consuming electrical energy themselves, or converting electrical energy into other forms of energy; at the same time, they only need to input signals and can operate normally without the need for an external power supply.

According to different industry definitions, the scope of passive components will be different, and sometimes RCL components are equivalent to passive originals.This question will focus on the RCL component market, that is, the market for capacitors, resistors, and inductors.Passive components appearing in this article refer to RCL components.Overall, as the most basic electronic components, the total demand for RCL components has steadily increased. With the demand for miniaturization and lightweight of downstream end products, chip components have become the mainstream of RCL components and the most important aspect of industry development. important driving factors.

The requirements for miniaturization and lightness of various end products have driven the global chip resistance rate to increase year by year. In 2012, the global production of chip resistors accounted for more than 90% of the total production of resistors. The development of chip resistors has had a great impact on the resistor industry. overall development plays a vital role.Thanks to global mobile phones entering the era of 3G, 4G, multimedia and smart phones, chip capacitors, chip resistors, chip inductors, etc. have increased by 50% or even several times compared with the previous generation of complete machines, and the demand for chip resistors has also increased. Increasing.

It is precisely because of the cornerstone role of passive components that their proportion in circuit components has gradually increased, and the market has grown steadily.Any circuit requires the use of passive components, and the number of passive components in circuits is also increasing steadily. In 1983, passive components accounted for only 21% of the PCB bill of materials, but by 2003, passive components accounted for an average of 80% of the PCB bill of materials. , accounting for about 20% of the cost.In terms of market size, the passive component market size reached US$24.24 billion in 2016 and is expected to reach US$3.289 billion in 2021, with a compound growth rate of 6.29%.In automotive electronics (3400 pieces), PCs (2200 pieces), LCD TVs (2100 pieces), iPhone 6 plus (1100 pieces), game consoles (1020 pieces), digital cameras (840 pieces), iPods (230 pieces), etc. Passive components are widely used in the field.

From a historical and development perspective, the passive component industry has mainly benefited from the rise of downstream terminal applications and markets. With the joint help of technological development and capital support, the related technologies of passive components and the corresponding market size have maintained steady progress and develop.Since 1990, the electronic product market has experienced several major waves such as the popularization of home appliances, PCs and recently smartphones, which has greatly stimulated downstream consumption and promoted the development of the entire semiconductor industry. Since 2012, semiconductor sales have shown a 3.9% growth rate. compound growth rate.Therefore, the passive component market in the upstream of the industrial chain has also been subject to such bottom-up transmission and pull, showing a steady upward trend. Compared with the 5.3% compound growth rate maintained by the semiconductor market size, the average annual compound growth rate of the passive component market size The growth rate has reached 6.29%, and the overall development trend is stable.

Capacitors are mainly used for charge storage, AC filtering or bypassing, cutting off or blocking DC voltage, providing tuning and oscillation, etc. They are widely used in DC blocking, coupling, bypass, filtering, tuning loops, energy conversion, and control in circuits. etc.
