1, this isYes, it is the earliest wireless charging CBB capacitor in the industry, and it is the most mature technology at present. The biggest advantage of CBB is that it is cheap, and it only costs a few cents.
2, the change is less than 0.2% in 50 years. The price of NPO capacitors is high compared to other capacitors. However, in applications with high precision requirements, the performance and advantages of NPO capacitors are irreplaceable. In addition, NPO capacitors have the advantages of low distortion, low noise and good frequency response. Therefore, despite its higher price, NPO capacitors are still widely used in high-end audio equipment, precisionWith 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 to find the remote controlScrews on the back of the instrument. 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, Huiwei and Maibo these two models can tell you, Huiwei work still need to be strengthened, the corner of the case peel off and warped more, which needs 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, 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 compatibility, so the cost ratioDirect charging is higher.
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, but the use of magnetic field to charge the device a technology, inspired by wireless power transmission technology. Magnetic resonance is used to transfer charge in the air between the charger and the device, then the coil and capacitor form a resonance between the charger and the device to achieve efficient transmission.
4. At present, Huawei does not launch a capacitor pen with wireless charging function. Its capacitor pen can be charged using AAAA non-rechargeable batteries or by manually turning the pen end. However, with the continuous development of technology, the capacitor pen with wireless charging function may be introduced in the future to provide a more convenient use experience.

Belkin Wireless charger Belkin YesApple's official cooperation brand, the quality is very OK at first do not understand the meaning of this thing is so stupid, later used it is inseparable, no longer used the data line.
LANWK is a very fast charging speed, very small wireless charger, full of national tide, things are good, thinner than imagined, charging response is fast, worth starting! Looks pretty, small and delicate, charging speed is very fast. NILLKIN's ambient lights are also great, and can be used as night lights at night! The charging speed feels acceptable, 40% of the charge is basically full in two and a half hours.
