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 10.0 mm or 12.5 mm.
Coating is made of blue colored flame retardant epoxy resin
in accordance with UL 94 V-0.
