With the complication of mobile phone product functions, the deepening of diversification, and the penetration of 5G communication networks, new applications such as multi-camera, 3D sensing, wireless charging, fast charging technology, wireless headsets, and under-screen fingerprint recognition are continuously developed and applied. Mobile phones need more advanced passive components to perform voltage stabilization, filtering, and current stabilization to ensure the normal operation of device components, and provide faster connection capabilities and more powerful processing capabilities.

Compared with active components, passive components mean that they cannot excite, amplify, or oscillate electrical signals. The response to electrical signals is passive and obedient, and electrical signals pass through electronic components according to the original basic characteristics. It is the cornerstone of the electronic circuit industry, and various electronic products contain passive components. Among the passive components, resistor, capacitor and inductor are the three main types.

Capacitors: The main functions ...
... are tuning, bypassing, coupling, filtering, energy storage, etc. According to different materials, it can be divided into ceramic capacitors, aluminum electrolytic capacitors, tantalum electrolytic capacitors and film capacitors.

Inductor: the main function is to filter signals, filter noise, stabilize current and suppress electromagnetic interference. According to the manufacturing process, inductors can be divided into two types: insert inductors and chip inductors. Chip inductors mainly include laminated chip inductors and wound chip inductors.

Resistor: usually plays the role of voltage division and shunt in the circuit. Can be divided into chip resistors and non-chip resistors.

Taking capacitors as an example, the upgrade of smart phones significantly increases the upgrade of stand-alone smartphones and significantly increases the use of stand-alone MLCCs. The number of MLCCs used for 2G / 3G mobile phones is 100-200. With the upgrade of communication technology, the number of MLCCs used in high-end LTE-A mobile phones reaches 550-900. Judging from the development history of Apple's mobile phones, the use of stand-alone MLCCs has also increased from 496 on the iPhone 4S to 1,100 on the iPhone X, with an overall increase of 122%. With the continuous introduction of 5G mobile phones of major brands, the MLCC market space will further expand.

In the field of inductor, in the field of inductor, 5G will also promote the further increase in the number of mobile phone stand-alone inductors. In 2008, the amount of inductors used in basic single-core 2G mobile phones was about 20-30 pieces. In the quad-core 4G era in 2017, the amount of single-chip inductors used in smartphones reached 60-90 pieces. The number of inductors will exceed 120.

Automotive electronics drives demand for passive components

With the continuous penetration of new energy vehicles, the demand for passive components in automotive electronics will continue to increase. With the continuous improvement of the electrification rate of automobiles, the specifications and complexity of bicycle control and power system components continue to increase. New energy vehicles have greater demand for key core components such as power recovery motors, power conversion units, and power batteries, and they have also increased accordingly demand for indispensable passive components in each component. From the perspective of the passive components used in each car, according to the data of the Solar Induction Act, the average usage of each mid-end car is about 6,300, the average usage of high-end cars is about 8,200, and the average usage of pure electric vehicles has increased to about 14,000. With the increase of new energy vehicle penetration in the future, the demand for passive components will continue to rise.

In the field of capacitors, the new energy trend of automobiles will continue to increase the demand for automotive products used in capacitors. The trend of new energy sources for automobiles will continue to increase the demand for capacitor products led by automotive MLCC capacitors. MLCC in automotive electronics is usually used in power engine, steering engine, idle stop, regenerative braking, engine drive and other links. The amount of MLCC used in different models varies widely. With the trend of new energy in automobiles, the amount of MLCC is expected to increase exponentially. According to the MLCC consumption data released by Murata, based on median calculations, the MLCC consumption of pure electric vehicles will reach about 5.5 times that of traditional internal combustion engine vehicles.

In the field of inductors, the automotive inductor market benefits from the rapid increase in penetration of new energy vehicles. Inductors are widely used in new energy vehicles, including ABS control unit, material / alarm, electric power steering, charging circuit, inverter / converter, HID / LED, ETC system, driving distance unit, SRS airbag, car navigation System, etc. According to forecast data from MarketsandMarkets, benefiting from the increase in penetration of new energy vehicles, the automotive inductive market in 2020 will be about 1.8 times higher than in 2016.
