Note 1
Voltage Ratings: All ratings are manufacturer’s
rating.
Part markings are governed by agency
rules and customer requirements.
Parts are marked 250 VAC unless otherwise
requested.
Note 2
UL1414 Across-The-Line, Antenna Coupling, and
Line-By-Pass Capacitors:
Across-The-Line—A capacitor connected
either across a supply circuit or between
one side of a supply circuit and a conductive
part that may be connected to earth ground.
Antenna-Coupling—A capacitor connected
from an antenna terminal to circuits within an
appliance.
Line-By-Pass—A capacitor connected between
one side of a supply circuit and an accessible
conductive part.
Note 3
IEC 384-14 Subclass Y Capacitors:
A capacitor of a type suitable for use in situations
where failure of the capacitor could lead to
danger of electric shock.
Class Y capacitors are divided into sub- classes
based on type of insulation bridged and voltage
ranges.
For definitions of basic, supplementary,
double and reinforced insulation, see IEC
Publication 536.
Subclass Y capacitors may be used in
applications which require a Subclass
X rating.
Note 4
IEC 384-14 Subclass X Capacitors:
A capacitor of a type suitable for use
in situations where failure of the capacitor
would not lead to danger of electric
shock.
Class X capacitors are divided into subclasses
according to the peak impulse test voltage
superimposed on the main voltage
Note 5
