FEATURES

• Complying with “EN 132 400” and “IEC 60384-14,

2nd edition, including amendment 1.1995”

• High reliability

• Kinked (preferred) or straight leads

• Lead (Pb)-free available

APPLICATIONS

• Across-the-line

• Line by-pass

• Antenna coupling

DESIGN

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 or 0.8 mm.

The capacitors may be supplied with kinked or straight leads

having a lead spacing of 7.5 mm (0.300") or 10 mm (0.400")

and a lead length from 4 to 30 mm. The standard tolerance

on capacitance is ± 10 % for U2M, Y5P material, ± 20 % for

Z5U, Y5U material and - 20/+ 80 % for Y5V. Encapsulation

is made of flammable resistant epoxy resin in accordance

with “UL94V-0”.
