SERIES M1206
EFC Series M1206 are polypropylene capacitors with double-sided metallized plates. This series
offers the advantages of a self-healing metallized dielectric and the high current/pulsing capabilities
(see dv/dt Table) of a metallized capacitor. Packaging options include: wrap and fill (TC, TF), radial
lead box (EFR), and radial lead dip (DFR).
