APPLICATIONS

• X1, Y1 according to IEC 60384-14.3

• Across-the-line

• Line by-pass

• Antenna coupling

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). The

capacitors may be supplied with radial kinked or straight

leads having a lead spacing of 0.375" (9.5 mm). The

standard tolerances are ± 10 % or ± 20 %. Coating is made

of flame retardant epoxy resin in accordance with

“UL 94 V-0”.
