POLYPROPYLENE and FOIL
SERIES 1206
EFC Series 1206 are polypropylene and foil capacitors. This series offers the advantage of superior
stability, high insulation resistance, low dissipation factor, negative temperature coefficient and high
frequency operation, dv/dt ratings in excess of 1000 V/µS. Suggested applications include: timing
circuits, switch mode power supplies (SMPS). snubber circuits. Packaging options include: wrap and
fill (TF, TC), radial lead box (EFR), axial lead (EC, EF). Application options include: snubber circuits
(MF), -270 PPM/0C temperature coefficient (T1206TC), -150 PPM/0C temperature coefficient
(A1206TC).
