SERIES MF1206
EFC Series MF1206 are polypropylene capacitors with an internal series construction of double-sided
metallized carrier and foil contact plates. This series offers the advantages of a self-healing metallized
dielectric and the high current/pulsing capabilities (see dv/dt Table) of a foil capacitor. Packaging
options include: wrap and fill (TC, TF), radial lead box (EFR), and radial lead dip (DFR).
