SPECIFICATIONS
EFC Series 1313 are metallized polyester capacitors. This series offers the advantage of
small size, self healing and low cost. Suggested applications include: medical electronics,
telecommunications and high voltage power supplies. Packaging options include: wrap
and fill (TF, TC), radial lead box (EFR), axial lead (EC, EF). Application options include:
high voltage (HV), "AC" across the line (AC), noise suppression (RC) and switching power
supply (SP).
