High voltage porcelain chip capacitor is a round plate capacitor with ceramic material as medium, in the “porcelain chip” capacitor bai is generally called low voltage below DC50v, DC100V~500V for medium and high voltage, DC1000v~6000v and for high voltage, the safety Y capacitor also belongs to high voltage, DC6000v above is super high voltage.
High-voltage porcelain chip capacitor role has the characteristics of wear-resistant DC high voltage, suitable for high-voltage bypass and coupling circuit, where the low-dissipation high-voltage disc has low dielectric loss, especially suitable for use in circuits such as TV receivers and scanning
Safety-rated capacitors are used in such a way that the failure of the capacitor will not lead to electric shock and will not endanger personal safety. It includes x capacitor and y capacitor. The x capacitor is the capacitor connected between two lines of power line (L-N), and the metal film capacitor is generally used; the Y capacitor is the capacitor connected between two lines of power line and ground (L-E, N-E) respectively, and is generally found in pairs. Based on the limitation of leakage current, the value of Y capacitor should not be too large, generally X capacitor is uF level, Y capacitor is nF level, X capacitor suppresses differential mode interference, Y capacitor suppresses common mode interference.
