HIGH VOLTAGE:
EFC high voltage metallized polyester capacitors are designed for use in high voltage power supplies,
rectifiers and other similar circuits. Voltage ratings to 15,000 DC are common-place at EFC.
Specify with the prefix
HV.
AC CURRENT:
Specify metallized polyester and termination procedures to enable EFC to supply a small sized
AC
rated
capacitor for general purpose use at 60 HZ. Specify with the prefix
AC.
HIGH AMPERAGE AND PULSE CURRENTS:
Dual metallized carriers allow these capacitors to handle high amperage and pulsing currents.
Available in both polyester and polypropylene dielectrics. Specify with the prefix
MF.
Contact the factory for an
MF
spec. sheet.
SWITCH MODE POWER SUPPLY:
Polypropylene and polyester capacitors designed for SMPS have low ESR and high current rating should
be specified with the
SP
prefix.
EFC will manufacture to any non-standard value and size. Please consult factory for special requirements.
