DESIGN
The capacitors consist of a ceramic disc of which both sides
are silver-plated. Connection leads are made of tinned
copper having a diameter of 0.032" (0.81 mm) or 0.025"
(0.64 mm). The capacitors may be supplied with radial
kinked or straight leads having a lead spacing of 0.375"
(9.5 mm) or 0.250" (6.4 mm). The standard tolerance is
± 20 %. Coating is made of flame retardant epoxy resin in
accordance with “UL 94 V-0”.
