Type WMC
Polyester Film/Foil Capacitors
Axial Lead, Miniature Size for Automatic Insertion
Type WMC axial-leaded polyester film/foil capacitors
are ideal for automatic insertion in printed circuit
boards. It is an ultraminiature version of Type WMF
and the sections of these non-inductive capacitors
are constructed with extended foil, polyster film, with
tinned copper-clad steel leads.
