Blue Ceramic Disc Capacitor 220pF 1000V Y5V P5mm For Transformer
High voltage ceramic capacitors is to belong to a kind of ceramic capacitors, are used to high dielectric constant of ceramics (barium titanate - titanium oxide) squeezed into a circular tube, the wafer or disk as a medium, coated metallic film (usually in the form of silver electrode through high heat sintering, tin copper clad steel wire, surface coating to protect the enamel, or with epoxy resin coating. The shape is blue wafer shape. Generally used in power systems, such as power system metering, energy storage, partial voltage and other products will use high voltage ceramic capacitors.
Features
High pressure resistance, low loss
Good frequency characteristics, with high stability
Special series structure is suitable for high voltage and long-term reliability
High current climbing rate and suitable for high current loop non-inductive structure
Insulation resistance, long use time
Applications
High voltage ceramic capacitors are used in high stability oscillating circuits as circuit capacitors and pad capacitors. And its main role is to remove high-frequency interference, so it is suitable for anion products, such as laser, X-ray machine, control equipment, igniter, transformer, power equipment, electrostatic spraying and other mechanical and electrical equipment need high voltage and high frequency.
