MEX are constructed with special metallized
polypropylene film dielectric, tinned copper wire
leads, encapsulated in plastic case with a non-
inductive epoxy resin seal. They are ideal for line
bypass, across-the-line, antenna coupling, spark
killer circuits, switching power supply and EMI filter
applications.
Optional suffix may be added to denote custom features
