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”.

Capacitors with 7.5 mm (0.30

")10 mm (0.40") lead spacing

The capacitors meet the essential requirements of “EIA 198”. Unless stated otherwise all electrical values apply at an ambient

temperature of 25 ± 3 °C, at normal atmospheric conditions.
