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), axial lead box (EC). Application options: -120 PPM/°C temperature coefficient (T1906TC, T1906EC), -80 PPM/°C temperature coefficient (A1906TC, A1906EC).
 

Specifications

  1. Temperature Range
    -55°C to +85°C at rated voltage.
  2. Capacitance
    Capacity shall be measured at 1 kHz ± 20 Hz. Measurements shall be taken at 25°C.
  3. Dielectric Strength
    At 25°C, 200% of rated voltage when applied terminal to terminal for one minute through a current limiting resistance.
  4. Insulation Resistance
    At 25°C 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.
  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°C for 250 hours with not more than one failure in 12 permitted.
