This is OK, it is the earliest wireless charging CBB capacitor in the industry, which belongs to the most mature technology at present. The biggest advantage of CBB is that it is cheap, and it only costs a few cents.
1, the cost is high: the charger needs to have the electronic circuit of the driving coil, and the electric device needs to have the electronic device of power conversion, both need to have the coil, and need the high-frequency filter circuit to meet the electromagnetic compatibilityTherefore, the cost is higher than direct charging.
2. This is indeed possible. In the scenario where the customer originally used TDK GRM315C1H104A01L, the market price was confused and the delivery was unstable due to the suspension of TDK production. In view of this situation, Dongguan Keya Electronics newly developed ultra-thin polypropylene film capacitor, which has reliable and stable performance, temperature rise and size adjustment of the circuit board can be placed. After 500 hours of aging test, it can be replaced with confidence after trial verification.
3, wireless charging technology does not use the charging line at all, but uses the magnetic field to charge the device as a technology, inspired by wirelessWith innovation and temperature as the principle, the development vision has changed from "building an international brand" to "becoming the world's most trusted brand", and "Building a hundred years of Hisense" remains unchanged.
Generally choose a wooden hammer or select an available object on the spot. When the press starts, the hammer hits the three solder joints on its body, but pay attention to the force and cannot knock deformation. Gently knock the compressor housing, the stuck part is slightly shaken loose, sometimes can start operation or the power supply voltage is increased by 10%, multiple start impact, this method can solve the problem of insufficient lubrication cylinder, especially effective for rotary compressors.
First, you need toFind the screws on the back of the remote. Usually, these screws are hidden in the back recess of the remote control and can be easily unscrewed with a screwdriver. You can then use a wire stripper to carefully separate the two halves of the housing. Finally, use tweezers to carefully remove the electronic components inside the remote control, making sure not to damage them. After the removal is complete, you can clean the internal circuit board, replace the battery, or repair any faults.
I can simply explain to you about the choice of knowledge, the two models of Huiwei and Maibo can tell you, Huiwei's work needs to be strengthened, the corner of the case peel off and warped morePoints need attention; Mai Bo some use power tube, power is large, watching the movie is very shocking, but the tone is not delicate enough.
Flat, generally can be followed by large 1P air conditioning. The size of the air conditioner is generally calculated in P (pieces).
1, wireless charging of mobile phones mostly uses the principle of electromagnetic induction. Electromagnetic induction wireless charging, when the current of the power supply is passed through the coil (the wire coil of the wireless charger)A magnetic field is generated, and when other unenergized coils (the charged coils on the phone) are close to the magnetic field, an electric current is generated to charge the phone.
2, several factors that affect the wireless charging speed: power plug power, power cord, wireless charger power, mobile phone wireless charging receiving power, mobile phone shell, mobile phone bracket. Now the wireless charger technology has been very mature, product quality stability is also very high, so when there is a problem, we should first check to eliminate the above problems, will save more time and trouble.
3, low power support: Millet wireless fast charge compatibility is strong, 10W power can also meet low power requirements. For power bank compatibility, the Xiaomi 30W vertical wireless charging and 20W versions offer flexibility when used alone. For example, the 80W Sail wireless charger requires 20V PPS/MiPPS protocol to activate the fast charge above 30W, while the Xiaomi 50W vertical charger Pro requires a specific charger above 67W to achieve its full potential.
4, first of all, the light of the millet wireless charger will blink when it starts charging, which is a normal phenomenon. But if the light keeps flashing, it may be caused by the following reasons: between the charger and the phoneThe distance is too far. Xiaomi wireless charger needs to fit with the phone to charge normally, if the distance is too far, the light will always flash. The charger port is loose.
