* OPTIONS
THE FOLLOWING OPTIONS ARE AVAILABLE FROM EFC BY SPECIFYING THE APPROPRIATE PREFIX.
TEMPERATURE COEFFICIENTS:
Different T.C.'s are available in both Polypropylene and Polystyrene dielectrics. T.C.'s and the appropriate prefixes
are as follows:
A1206 = -150 PPM/OC +30 PPM
T1206 = -270 PPM/OC +30 PPM
01906 = ZERO PPM/OC +50 PPM
A1906 = -80 PPM/OC +30 PPM
T1906 = -120 PPM/OC +30 PPM
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 sizedAC 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.
