Ultra-high Voltage Ceramic Capacitors Molded type with metal terminals For distribution lines FD(Eac: 10 to 25kV) series Issue date: June 2011 • All specifications are subject to change without notice. • 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. (1/2) Ultra-high Voltage Ceramic Capacitors Molded Type with Metal Terminals FD Series Conformity to RoHS Directive 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, lowdistortion 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.

(2) During operation • Avoid contact with electrolytes such as perspiration. Do not touch with bare hands. • Avoid excessive impact such as that caused by falling. • Do not apply solder to stud terminals. • Do not re-machine the terminals. (3) Usage • Make sure that the capacitor is not exposed to radiant heat from chambers or transformers. • For more information about products with other capacitance or other data, please contact us. • All specifications are subject to change without notice. 005-01 / 20110630 / e4e39a_fd.fm
