POLYSTYRENE and FOIL
SERIES 1906
EFC Series 1906 are polystyrene and foil capacitors. This series offers the advantage of extremely high insulation resistance (IR), low dissipation factor and very low dielectric absorption. 1906 have a linear negative temperature coefficient. Applications include: timing circuits and filters. Packaging options include: wrap and fill (TC), radial lead box (EFR), axial lead (EC, EF). Application options: -120 PPM/0C temperature coefficient (T1906), -80 PPM/0C temperature coefficient (A1906).
SPECIFICATIONS
1. TEMPERATURE RANGE
- 55 C to + 85 C at rated voltage.
O O
4. INSULATION RESISTANCE
At 25 OC after 2 minutes charge time at rated voltage or 500 VDC, whichever is less, the minimum IR shall be 500,000 Megohm-Microfarads, but need not exceed 1,000,000 Megohms.
2. CAPACITANCE
Capacity shall be measured at 1KHz +20 HZ. Measurements shall be taken at 250C.
3. DIELECTRIC STRENGTH
At 25 OC, 200% of rated voltage when applied terminal to terminal for one minute through a current limiting resistance.
NS SIG DE EW RN T FO NO
5. HUMIDITY RESISTANCE
Series 1906 shall meet the requirements of MIL-STD. 202C, Method 103B.
6. DISSIPATION FACTOR
Shall be 0.1 % max. when measured as in Par. 2.
7. LIFE TEST
Will withstand the application of 140% rated voltage at +85 0C for 250 hours with not more than one failure in 12 permitted.

* 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 T1206 01906 A1906 T1906 = = = = = -150 PPM/OC +30 PPM -270 PPM/OC +30 PPM ZERO PPM/OC +50 PPM -80 PPM/OC +30 PPM -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 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.
