Dongguan Zhixu Electronics Co., LTD., a ceramic capacitor manufacturer with rich experience, has developed into a professional since its establishment in Taiwan in 1997Enterprises engaged in ceramic capacitor production. In order to better serve the mainland market and improve delivery efficiency, Zhixu Electronics set up a branch in Dongguan.
Zhixu electronics is very good, wireless charger ceramic capacitor number is complete, parameter information is complete, manufacturers can also reasonably assist.
To reduce noise, a number of strategies can be adopted. For example, the bottom protective layer of the ceramic capacitor is increased to avoid excessive deformation caused by the solder; The metal bracket structure is used to isolate the inverse piezoelectric effect. Reduce vibration transmission through structural optimization; Or choose non-piezoelectric capacitors such as tantalum capacitors, but pay attention to its ESR and heating problems. vThe shell will shield electromagnetic waves, so glass or other non-metallic materials are used as the shell. In theory, the glass will not block wireless transmission, but because the glass is thick, it will also reduce the efficiency of wireless charging. Wireless charging technology comes from radio energy transmission technology, which can be divided into two ways: low-power wireless charging and high-power wireless charging.
Because the energy loss in the propagation process is small, the transmission efficiency is high, so as to ensure that the load can run normally.
The iPhone has not been fast charging or wireless charging, it is said that because they think the technology is not mature, the phone hardware is close to the bottleneckIt would be a good idea to add this feature.
may affect heat dissipation, at this time you can take off the phone case and recharge; Wireless charging: the standard protective shell of the mobile phone has no effect on wireless charging. If other protective shells are used, it is recommended to remove the protective shell and then wireless charging the mobile phone. Note: The metal protective shell will interfere with the wireless charging signal and affect the wireless charging function. In order to get a good charging experience, please use non-metallic protective case, it is recommended to use the original protective case.
To achieve wireless charging technology. Iron has a shielding function if you need to use wireless chargingYou can't use a metal back. Wireless charging technology comes from radio energy transmission technology, which can be divided into two ways: low-power wireless charging and high-power wireless charging. Low-power wireless charging often uses electromagnetic induction, such as the Qi method of charging mobile phones, but ZTE's electric vehicle wireless charging method uses induction.
The answer is yes, but only for non-metal phone cases. In simple terms, Qi standard wireless charging is to transmit power through electromagnetic fields, and metal will cause certain interference to the transmission process. There are rumors that these negative effects may cause the device to fail to charge properly,Or overheating damage, etc., which is why Samsung and Apple use glass panels on new machines.
1, taking iPhone13pro as an example, Apple 13pro built-in lithium-ion rechargeable battery, wireless charging, wireless charging power up to 15W, can support Qi wireless charging and MagSafe magnetic wireless charging. Charging via a USB connection to a computer or power adapter is also fast, with a 50% charge in about 30 minutes, using 20 watts or moreHigh power adapters (available separately).
2, support wireless charging mobile phones are: millet Samsung S10 series, millet MIX2S, millet MIX2S, Huawei Mate20PRO, iPhoneX, iPhone8 and iPhone8Plus. Wireless charging technology comes from radio energy transmission technology, which can be divided into two ways: low-power wireless charging and high-power wireless charging.
3, some mobile phones support wireless charging function, mobile phones that support wireless charging are: Huawei Mate 40E Pro, Huawei P50Pro, Huawei Mate 40E, Huawei Mate 40 Pro, Huawei Mate 30 Pro, Huawei Mate 20 Pro, Huawei P40 Pro, etc.
4, Mi 9. The Mi 9 mobile phone was released on February 20, 2019, and in addition to the Qualcomm 855 chip, this product has made rapid progress in wireless charging. The Mi 9 mobile phone is equipped with the world's first 20W wireless flash charge, which is comparable to the wired fast charge.
2, mobile phone wireless charging is not popular, mainly because the experience of wireless charging is very rubbish. Of course, the high price is also a very important factor. In terms of experience, mobile phone wireless charging has shortcomings. Compared to wired charging methods, handWireless charging is not only slow, but also very inconvenient to use wireless charging. Slow charging speed: Since the Samsung Note 7 explosion, mobile phone wireless charging power has been castrated by manufacturers.
3, wireless charging charging speed is very slow, which is hard. Now is the world of high-power fast charging, although each fast charging solution is not the same, but the power is maintained at about 18w, high and even to 24w, accustomed to an hour and a half full, but now to return to the past, 5w 8w maximum 10w charging speed, is not acceptable, but also can not move, the position is offThe speed is lower. Second, the speed of wireless charging is really very slow, extremely low efficiency, its power is mostly within ten watts, and our mobile phone now wired charging power is generally more than 18 watts.
5, support wireless charging for the factory flagship machine, the price is too expensive, which should be a very important factor. Looking at all the models that support wireless charging on the market at present, most of them belong to the flagship positioning and are expensive, such as Samsung Galaxy series, Apple iPhone X, iPhone8 series, the price of these products is very highFive or six thousand yuan, or even higher, doomed its audience is relatively small.
