In addition, in North America, Designations of
Across-the-Line capacitors, Antenna couplings, and
Line bypass capacitors refer to the following
applications:
OUTLINE OF CAPACITOR CLASS RATINGS
Capacitor are classified by the IEC into two
categories (these designations are used by most
European countries).
Class Y: Capacitors used in applications where
damage to the capacitor may involve
danger of electrical shock.
Class X: Capacitors used in applications where
damage to the capacitor will not lead to the
danger of electrical shock.
These X and Y Classifications are further divided
into subcategories as shown in the tables.
(Ref. IEC60384-14, 2nd edition, 1993)

Okaya characterizes all capacitors using the standard test procedures outlined in JIS C 5102, 5150, 5151.
These test parameters are confirmed by a Q.A. audit and are published as guaranteed specifications shown as
"dielectric withstanding voltage".
Okaya performs 100% screen testing of all capacitors during the production process. These tests are subject to
changes due to improvements in test equipment and procedures and are published for reference only.
