Follow me, let you know the industry chain of passive components and market trends
The most common passive components are (resistor, capacitor, inductors, diodes) and so on. In terms of function, passive components have the characteristics of being able to work normally without requiring an input signal and no external power supply, and they can convert electrical energy into different forms of other energy without consuming electrical energy.
1. The demand for SMD resistor is steadily increasing
Resistor are two-terminal electronic components that can limit the flow of current in the circuit. There are three categories of resistor (fixed resistor, variable resistor, and special resistor). Fixed resistor are commonly used in electronic products. As one of the main electronic components, the output accounts for about 40% of the entire electronic components. Mainly used in the circuit to adjust and stabilize current and voltage
2. Ceramic capacitor MLCC potential is the focus
The intuitive understanding of capacitance is a container for storing electric charge. The basic structure and principle is that two pieces of metal are separated by a substance in the middle. As one of the main electronic components, the output of capacitor has shown an overall upward trend with the rapid development of information technology and electronic equipment. It accounts for 40% of the entire electronic components.
Ceramic capacitor MLCC has the characteristics of (low ESR, high voltage resistance, high temperature, small size, and wide capacitance range), which is quite dominant and has a wide range of downstream applications. Its market size accounts for about 93% of the entire ceramic capacitor.
The growth rate of the inductor market is still growing steadily. In 2019, my country’s demand for inductors reached 151.2 billion, an increase of 29.8% year-on-year, and reached 224.5 billion in 2020. It is expected that my country’s demand for inductors will exceed 240 billion in 2021. In recent years, the domestic market’s annual demand for inductors is average The growth rate exceeds 8.2%.
At present, from the perspective of the supply of domestic passive device manufacturers, the main layout is in the mid-end market, and the products are cost-effective; the high-end market is also continuously researched and developed, the technological gap is gradually narrowing with foreign manufacturers, and the production capacity of domestic enterprises is accelerating, combined with the demand brought by enterprise innovation. The mainland supply chain will usher in a wave of key breakthroughs.
