Applied to the power supply circuit, bypass, decoupling, filtering and energy storage, commonly used in power modules, high-pressure liquid crystal display inverter board, LED RC Buck Power, (INVERTER) inverter, automotive xenon lamp (HID Electronic Ballasts ), ASDL voice splitter, RJ45 Ethernet interface, digital camera flash, LED Christmas string lights energy-saving lamps and high-frequency electrodeless lamps, electronic ballasts and other products;. Chip Varistor MLCV products in the mobile phone, PDA, MP3, MP4 and computer motherboards and other fields have broad application prospects characteristics of high-voltage chip capacitors: 1. Use a thin layer and multi-layer stack technology SMD ceramic capacitor dielectric layer, so that the capacitance value greatly expand 2. monolithic structure ensure excellent mechanical strength and reliability 3. high accuracy, a high degree of accuracy during the automatic 4. Just because the assembly of ceramic and metal, so even at a high temperature, low temperature environment no gradual decline phenomenon, with strong reliability and stability 5. The distribution characteristics of low capacitance can be done close to the theoretical value of the circuit design 6. residual induction coefficient is small, to ensure a good frequency characteristics 7. field because electrolytic capacitor also received a capacitor, so longer life, but made with a high reliability of the power supply 8. Because of the low ESR, the frequency characteristics of a good, it is best suited for high frequency, high power ceramic multilayer chip capacitors advantages and characteristics of high-density type : 1. Can be used to make a small, powerful product. 2. Help to improve production efficiency, automated production. 3. The use of precious metals production, high stability, high temperature, high reliability and long life. 4. You can replace the CBB, aluminum electrolytic, so that miniaturization of electronic products, save space. Products more attractive and better performance. 5. Ceramic small ESR can be used in some high-frequency circuit, higher product efficiency.
