Ultra-high Voltage Ceramic Capacitors
Molded Type with Metal Terminals FD Series
FOR HIGH VOLTAGE POWER CIRCUIT/AC HEAVY DUTY
Temperature range: –30 to +85°C/Capacitance temperature characteristics: Y5P (±10%)
CLASS 2 HIGH DIELECTRIC
Molded from resins that provide outstanding insulation and moisture resistance, these capacitors are ideal for high-voltage power
circuits in electrical power transmission and receiving devices.
FEATURES
• They are compact in size and exhibit excellent low-loss, low-
distortion characteristics.
• Capacitance values are largely unaffected by variations in
applied voltage.
• Internal screw thread design simplifies mounting requirements.
APPLICATIONS
• High voltage surge absorbers, gas circuit breakers in electrical
power transmission and receiving devices, and lightning
arresters.
• Voltage distribution elements in high-voltage measuring devices.
• Impedance matching in transformers and high-voltage AC
circuits.
