MLCC commonly used C0G (NP0), X7R, Z5U, Y5V different media specifications, different specifications have different characteristics and uses. C0G, the main difference X7R, Z5U and Y5V are they fill a different medium. In the same volume due to the different capacity of the capacitor dielectric filler consisting of different, dielectric loss, the capacity of the capacitor and brought stability and the like is different, it should be used in accordance with the capacitor in the capacitor circuit to a different role selection of different capacitors. Second, the details: 1. The use of thin layer and multi-layer laminated technology SMD ceramic capacitor dielectric layer, so that the capacitance value greatly expand 2. The monolithic structure ensure excellent mechanical strength and high reliability 3. accuracy during automatic assembly due to a high degree of accuracy 4. Just ceramics and metal, so even if no gradual decline phenomenon at high temperatures, low temperatures, with strong reliability and stability 5. low capacitance characteristics distribution can be done close to the theoretical value of the circuit design 6. residues induced conductivity, to ensure a good frequency characteristic 7. The result also obtained electrolytic capacitor capacitance field, so longer life, more built in with high reliability 8. Due to the low power ESR frequency characteristics of a good, it is most suitable for high frequency, high power density type // high-capacity high-voltage SMD chip capacitors 0805 X7R 100V, 250V, 500V series? 0805 NPO 100V, 250V, 500V series ? 1206 X7R 100V, 250V, 500V, 1KV, 2KV series? 1206 NPO 250V, 500V, 1KV, 2KV series? 1808 X7R 1KV, 2KV, 3KV series? 1808 NPO 2KV, 3KV series? 1812 X7R 100V, 250V, 500V, 1KV , 2KV series? 1812 NPO 330 1KV? 1210 X7R 250V, 500V, 1KV Series 1210 NPO 250V, 500V, 1KV Series 2220 X7R 100V, 250V, 500V, 1KV, 2KV series 2225 X7R 100V, 250V, 500V, 1KV, 2KV series LED lamps commonly used high-voltage chip and large-capacity chip capacitors specifications.
