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.

• In addition to the above, products are available that can be used in SF6 gas without modification (S type: molded with epoxide resin; alumina filler).
• Conformity to RoHS Directive: This means that, in conformity with EU Directive 2002/95/EC, lead, cadmium, mercury, hexavalent chromium, and specific
bromine-based flame retardants, PBB and PBDE, have not been used, except for exempted applications.
• All specifications are subject to change without notice.
