1, according to the structure of three categories: fixed capacitors, variable capacitors and fine tuning capacitors. Classification by electrolyte: organicMass capacitors, inorganic dielectric capacitors, electrolytic capacitors, electric capacitors and air dielectric capacitors. According to the use of: high frequency bypass, low frequency bypass, filtering, tuning, high frequency coupling, low frequency coupling, small capacitor.
2, mica capacitor (CY), withstand voltage (250v-450v), small capacity, very expensive, large volume. For important parts of the communication machine. There are tantalum capacitors (CA), niobium capacitors (CN), thin film capacitors and so on.
3. Types of capacitors Fixed capacitors Variable capacitors electrolytic capacitors are explained in detail as follows: Fixed capacitors fixed electricityContainers are the most common type of capacitor. It has a fixed capacitance value and is not adjustable. According to their structure and media, fixed capacitors can be divided into paper capacitors, mica capacitors, ceramic capacitors, metallized film capacitors and so on. 4, there are many types of capacitors, which can be divided into: non-polar variable capacitors, non-polar fixed capacitors, polar capacitors, etc., from the material can be divided into: CBB capacitors (polyethylene), polyester capacitors, porcelain capacitors, mica capacitors, monolithic capacitors, electrolytic capacitors, tantalum capacitors, etc. Non-inductive CBB capacitor: 2 layers of polyvinyl plastic and 2 layers of metalThe foil is alternately mixed and then bundled.
1, Millet 55W vertical air-cooled wireless charging using PC flame retardant material plastic shell wireless charging special cbb capacitor , fuselage edge clear end Angle arc transition wireless charging special cbb capacitor , the support plate is black > Wireless charger dedicated cbb capacitor , base sandblasting is gold. From the front, the front end of the base is equipped with LED indicators, and the support board is layered above and below, using different designs. Indicator light is green when working.
2, millet vertical air cooled wireless charger price is 199 yuan, millet car wireless fast charge price is 139 yuan. Recently, Xiaomi's 5G era charging technology media communication conference held in Beijing can be said to be brilliant, high-profile display of the world's first 30W super wireless flash charging technology, and in the follow-up millet 9PRO conference also released related accessoriesProduct, 199 yuan vertical air cooled wireless charging seat, or very worth buying oh. 3, in general, millet 100W wireless charger and previously disassembled 80W wireless charger appearance, details, size are the same, only the difference in color, may be the beginning of the design also want to help consumers to distinguish through the difference in color. A glance at the back of the two wireless chargers. The net weight of the entire wireless charging base is about 205g. Wireless charging supports free charging of mobile phones horizontally and vertically, taking Xiaomi 11 mobile phones as an example, wireless charging can be vertically and vertically while processing information.
4, millet wireless chargeElectrical millet vertical air cooled wireless charge 55W millet 10th anniversary speech Lei always follow the millet 10 supreme commemorative edition of the product released together. Charge the Mi 10 Supreme commemorative Edition at the fastest 40 minutes to reach 100%, to achieve a full day of battery freedom. Built-in quiet cooling fan, six intelligent protection mechanism, safer charging. Input Wireless charger cbb capacitor : 5V-20V = 25A Max Input Wireless charger cbb capacitor : 55W Max. Product does not include charger toAnd data cable.
5, millet vertical air-cooled wireless charger (55W black) 199 yuan at present millet maximum power (charging speed is the fastest) wireless charger, if the phone is 30W or 33W wireless charging power, then it is recommended that you "redundant" to buy this power of the wireless charger, because the mobile phone upgrade faster, The wireless charger this product can be used for several years, and the new mobile phone can also achieve power coverage in the future.
6, Mi 9 all series mobile phone standard 27W wired flash charging source adapter, charging time is faster. Data development: MilletThere are many charging devices, such as mobile phones can now realize wireless charging.
2, the use method is as follows: After plugging in the power supply, touch the curved light pole with your finger at any position to light the light. Put the device that needs to be charged under the lamp, switch the mobile phone to the wireless charging mode, and put it into the wireless charging induction area of the lamp. Use the phone charging cable to connect the lamp USB port to the phone, and the phone can also be charged.
3, very simple, regular discharge. For example, every month (if there has been no power failure), do not plug in the AC plug, turn on the light, until the light is not bright, indicating that the electricity has been discharged. Replug acElectricity will do.
4, when you are charging, then the voltage of the charger is used, the voltage of the charger is higher than the voltage of the battery to charge normally, when you unplug the power, then the lamp uses the battery electricity, so the brightness of the lamp should be slightly lower.
5, How to use Huawei wireless charging lamp? In addition to being able to turn on and off by touch, there are more detailed adjustment functions on its panel, which can be adjusted continuously with a finger swipe, and the experience is exactly the same as adjusting the brightness of the mobile phone, and because this operation does not involve mechanical movement, soSo there will never be wear and tear and aging, and the experience will be the same no matter how long you use it.
6, this kind of music desk lamp generally can not give mobile phone wireless charging, now wireless charging words only that kind of small disc, like you this kind of music desk lamp it must still need a line connection, there is no connection then it must be that, well, there is not much of the role, so you still need to pass a certain connection. Technology that uses magnets to charge devices.
circle is divided into 2 half wireless dedicated cbb capacitors , 1 half is black for negative wireless dedicated cbb capacitors , and half is colorless for positive. The black shadow on the left is the negative terminal, and the right is the positive terminal. The capacitor position on the motherboard, if it is black and white, the black part is negative, and the white part is positive. If it is white or black and colorless, the part that is painted white or black is negative, and the part that is not painted is positive. Under normal circumstances, the range of negative painting part is small.
In-line electrolytic capacitorDistinguish between positive and negative poles. The positive and negative electrodes of the in-line electrolytic capacitor can be distinguished by the length of the pin and the color of the housing, and the pin length is a positive wireless charger dedicated cbb capacitor ; Short pin is negative; The gray part of the housing with a small area corresponds to a negative pin and the other end is positive. For encapsulation, the positive terminal is generally indicated by marking ""; Or the negative electrode can be represented by a painted area. Aluminum electrolytic capacitors distinguish between positive and negative electrodes.
marking: Electrolytic capacitors are usually marked with positive and negative electrode identification on the housing, such as the "" and" - "symbols. Length: The positive pin of the electrolytic capacitor is usuallyLonger than the negative pin, which can also be used as a way to distinguish. Polarity identification: Electrolytic capacitors usually have polarity identification on the schematic, such as an arrow pointing to the positive pole. On the schematic, the positive and negative electrodes of the electrolytic capacitor can also be identified by polarity identification.
1, this is OK, it is the earliest wireless charging CBB capacitor in the industry, which belongs to the most mature technology. The biggest benefit of CBB isIt's cheap. It only costs a few cents.
