DESIGN

The capacitors consist of a ceramic disc which is silver

plated on both sides. Connection leads are made of tinned

copper having diameters of 0.6 mm or 0.8 mm.

The capacitors may be supplied with straight or kinked

leads having a lead spacing of 12.5 mm.

Coating is made of blue colored flame retardant epoxy resin

in accordance with UL 94 V-0.
