1. tdk is a famous brand of electronics industry. In 1930, Dr. Kato and Dr. Goro and Dr. Takei invented the magnetic material known as ferrite, which was the world's first ferrite core. In 1935, in order to commercialize ferrite, Tokyo DenkiKagaku Kogyo K.K was founded by Kenzo Saito.
2. tdk: manufacturer of electronic devices. According to the company's official website, TDK established four world-renowned innovative technologies (ferrite materials, magnetic tape, laminated components, and magnetic heads) in 1935.It has continuously created innovative products that promote social development. We will continue to contribute to the creation of customer value by providing high-quality products and services by leveraging diverse global management resources as a company that further challenges innovation.
3. TDK is a famous brand. At the beginning, the company's name was Tokyo Electro-Chemical Industry Co., LTD. The name was formerly known as the Department of Electrochemistry at Tokyo Institute of Technology. The inventors of ferrite, Dr. Kato Yogoro and Dr. Takei, taught at the university's Department of electrochemistry. In 1983, the name was officially changed to the current TDK Corporation,It is the initial of the original name Tokyo (Tokyo) Denki (electrical) Kagaku (chemical).
4, the company's highly authoritative professional technology for magnetic materials, but also developed a well-known TDK tape. With the diversified development of the business, the company's name is also shortened to TDK (or Chinese company translation: Dong Dong Chemical). Today, TDK Group has grown into the world's leading manufacturer of electronic components and recording media, with development, production and sales sites in 21 countries and more than 30,000 employees.
5, TDK -- allBall largest computer hard disk head manufacturer West Number. Do their own Wafer technology is not good, its single disc 500G magnetic head is mainly TDK company to help it do, and now even Seagate and Hitachi do 500G Wafer have problems, also need TDK company to help them do. Needless to say, Samsung's hard drives are manufactured by TDK's branch in Dongguan. It can be said that in a single disk 500G capacity of the magnetic head, TDK is the largest.
6, Wuxi Dongdenhua Landa Electronics Co., LTD. Formerly known as Wuxi Lianmeilanda Electronics Co., LTD., was founded by Japan Densonlanda Co., Ltd. in 19A wholly owned subsidiary invested in China in 1995. In March 2008, Densonlanda Corporation became a wholly-owned subsidiary of TDK Corporation, and the company name was changed to TDK-Lambda Corporation in October 2008.
Qi wireless charging has requirements for charging distance, and the maximum charging distance is only 10 mm. This is a bit "blocking" for Chinese mobile phone users who like to use mobile phone cases, although there is no need to remove the mobile phone case, the thickness of the mobile phone case has requirements, and some charging plates are marked, and the thickness of the protective case should not exceed 3 mm. Since most smartphones that support wireless charging use Qi wireless charging standard technology.
If this technology is successfully developed, the future of wireless charging will be like WiFi, realNow single-to-multiple charging, covering a distance of 5 meters, power up to 500 watts, which undoubtedly brings great development prospects for wireless charging technology! At present, most of the mainstream products on the market use electromagnetic induction technology and follow the Qi standard. As long as it is a charging bank/base (transmitter end) that meets the Qi standard, it can charge the rear shell/protective shell (receiver end) of the Qi standard mobile phone.
Now the main problem of electric vehicles is that the charging time is too long, the efficiency is too low, and from a long time ago, there are companies that have proposed to use wireless charging technology in the car, and recently there are companies that have done it, but at presentIt is only being tested on a small scale, and it is difficult to popularize it in the future. In fact, before this road wireless charging began, there have been companies that have used this technology, but the final effect is not very ideal.
In theory, it can power electronic devices such as mobile phones anytime and anywhere. However, wireless charging can not be transmitted as far as WiFi for the time being, and now mature solutions can only achieve wireless charging within a distance of 10mm, generally a distance of about 3~5mm is better, such wireless charging technology uses magnetic induction wireless charging technology. Wireless charging requires a transmitterAnd a receiving end. The transmitter is the wireless charger, the receiver is the mobile phone and so on.
There are three main types: inductance, resonance and radio waves at present, the main application of electromagnetic induction technology and vibration technology two kinds of electromagnetic induction: the primary coil of a certain frequency of alternating current, through electromagnetic induction in the secondary coil to produce a certain current, thereby transferring energy from the transmission end to the receiving end.
