Since the introduction of Taiwan process technology in 1988, Zhixu Electronics has focused on the research and development and production of safety capacitors, and has passed ISO9001:2015 quality management system certification, including the United States UL, Germany VDE, Canada CSA and so onMultiple international certifications. The company pays attention to product quality, from the production of porcelain chips to the processing of finished products, and adopts 7 quality inspection processes to strictly control the quality.
And the current market wireless chargers are mainly divided into well-known brands and third-party brands, of which the consumer electronics brand wireless charging terminals are produced by foundries, while the third-party brand products are partly self-produced and partly from OEM, at present in the third-party charger market, the domestic is still in a state of disorderly competition, the market pattern is more chaotic. With the gradual development and maturity of wireless charging technology, wireless charging will expand to more application scenarios in the future.
1, engaged in electronic components agent, distribution, the main products are AD, ST, AT, TI, PHI, NS, MAX and other brands of integrated circuits, transistors, capacitors and resistors. Jingrui Electrical Hardware Co., Ltd. manufactures LED, diode, electronic components. Dasheng Electronics Co., Ltd. produces in-line capacitors, voltage regulator tubes andThe triode. Agent SMD electronic components.
2, the maximum current that can be passed by the two resistors together is 2*27=54A, which should have enough margin for the output of 12V power supply in the circuit. CC41:0.5pF ~ 0.22uF CT41:220pF ~ 100uF Voltage 16V indicates the maximum voltage that the capacitor can withstand. Considering the long-term reliability of components, the actual operating voltage of the capacitor is generally selected to be less than 75% of its maximum voltage.
3, most of the capacitors are electrolytic capacitors, and there is a large inductanceTherefore, the impedance will increase after the frequency is high. Sometimes it will be seen that there is a large capacitance electrolytic capacitor in parallel with a small capacitor, at which time the large capacitor passes the low frequency and the small capacitor passes the high frequency. The role of the capacitor is to pass high and low resistance, and pass high frequency and low frequency. The larger the capacitance, the easier it is for low frequencies to pass through. Specifically used in filtering, large capacitance (1000μF) filter low frequency, small capacitance (20pF) filter high frequency.
4, simple summary: resistance: current limiting effect, similar to the small diameter pipe between two large diameter pipes to limit the role of water flow, can also protect the circuit. Capacitor: A capacitor is a type of electric charge that can be stored. electricityThe no-load current is very small. The receiving end also adopts the mode of resonance, which can maximize the transmission efficiency of energy, and the direct current is obtained by the filtered capacitor after the Schottky diode is rectified, and the charging current is above 0.6A. If the coil is made into a barrel shape, the transmission efficiency will be higher.
The reason why the wireless charging circuit should use LC output is as follows: The charging method of the wireless charger is to use the induced magnetic flux generated between the wireless charging board and the induction magnet on the mobile phone, and convert this magnetic force into a power for current transmission.
Dongguan Zhixu Electronics Co., LTD., a ceramic capacitor manufacturer with rich experience, has developed into a professional enterprise engaged in ceramic capacitor production since its establishment in Taiwan in 1997. 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.
This is indeed OK, customerIn the original scenario of using TDK GRM315C1H104A01L, the market price is confused and the delivery is unstable due to the suspension of TDK production. In view of this situation, Dongguan Keya Electronics has developed a new ultra-thin polypropylene film capacitor, which has reliable and stable performance, temperature rise, and can be placed after adjusting the size of the circuit board, and can be replaced with safety after 500 hours of aging test and trial verification.
The use of magnets to instantly charge more than one device without the use of wires, this technology allows devices to be charged wirelessly up to a few meters away from the charger, Fujitsu's wireless charging technology uses magnetic resonance to chargeThe electrical charge is transferred in the air between the appliance and the device, and the coil and capacitor form a resonance between the charger and the device.
