Multilayer ceramic chip capacitor is stable and has high capacitance. Laminated monolithic structure, excellent solderability and solder resistance, MLCC capacitors are suitable for reflow and wave soldering, various filtering and coupling circuits.
High voltage chip capacitors, also known as ceramic multilayer chip capacitors, are a kind of production technology using ceramic powder, the interior is precious metal palladium, and silver is plated on ceramics as electrodes by high-temperature sintering. The products are divided into high frequency porcelain NPO (COG) and low frequency porcelain X7R. NPO has a small package size, high temperature coefficient capacitors, and good high-frequency performance. It is used in high-stability oscillation circuits as circuit filter capacitors. X7R ceramic capacitors are limited to bypassing or blocking DC in circuits with ordinary frequencies, or where stability and loss are not required. Such capacitors should not be used in alternating current (AC) pulse circuits, because they are easy to be used by Pulse voltage breakdown, so it is not recommended for use in AC circuits.
