TDK FD Series specifications For High Voltage Power CIRCUIT/AC Heavy Duty, Features, Applications

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 mois- ture 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.
