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 sec-
tions of these non-inductive capacitors are constructed
with extended foil, polyster film, with tinned copper-
clad steel leads.
