Flattened Polyester Capacitors

 The Arco MMF Series of metalized polyester capacitors are constructed of metalized polyester film dielectric with copper ply leads and an outer wrap of polyester film tape. The ends are sealed with an epoxy non-inductive resin. They offer high stability, DF versus temperature, and are self-healing which enhances reliability in an extremely small size.

The MMF Series is excellent for use in AC circuits, coupling, by-pass, R.F. filtering, and solid state applications.
