DESCRIPTION
The capacitors consist of a ceramic
disc both sides of which are
silver-plated. Connection leads are
made of tinned copper having a
diameter of 0.6 mm.
The capacitors are supplied with
straight leads. The standard
tolerance on capacitance is ±20%.
Encapsulation is made of flammable
resistant epoxy resin in accordance
with
“UL94V-0”
.
