Radial Leaded Ceramic Disc Capacitors
Safety Standard Recognized, C900, Encapsulated,
AC Type, X1 440 VAC/Y2 300 VAC (Industrial Grade)
Overview
KEMETs 900 encapsulated radial leaded ceramic disc With a working voltage of 440 VAC in line-to-line (Class X)
capacitors are specifically designed for interference-sup- and 300 VAC in line-to-ground (Class Y) applications, these
pression AC line filtering applications. Having internation- safety capacitors meet the impulse test criteria outlined in
ally recognized safety certifications, these capacitors are IEC Standard 60384. Meeting subclass X1 and Y2 require-
well-suited for applications that require keeping potentially ments, these devices are certified to withstand impulses up
disruptive or damaging line transients and EMI out of sus- to 4 KV (X1) and 5 KV (Y2) respectively. These encapsulated
ceptible equipment. They are also an ideal solution when devices also meet the flame test requirements outlined in UL
needing to suppress line disturbances at the source. Standard 94V0.
Safety Certified Capacitors are classified as either X and/
or Y capacitors. Class X capacitors are primarily used in
line-to-line (across-the-line) applications. In this applica-
tion, there is no danger of electric shock to humans should
the capacitor fail, but could result in a risk of fire. The class
Y capacitor is primarily used in line-to-ground (line by-pass)
applications. In this application, failure of the capacitor
could lead to danger of electric shock.

Due to a high risk of arcing,Inside Kin lead configuration cannot be combined with the 5 mm lead spacing option. TheInside Kin option is only
available on capacitors with lead spacing of 7.5 mm or greater. A potential for arcing may exist when combining theInside Kin lead configuration
with a 7.5mm lead spacing option, especially in high humidity environments and/or when exposure to voltages and transients may impact creepage and
clearance requirements.

Capacitor body diameter will limit available lead spacing and packaging options. SeeDimension andProduct Ordering Codes and Rating sections
of this document to determine availability.

Vertical Kin,Outside Kin andInside Kin lead configurations cannot be combined with the bulk/20 mm lead length option (WL20). 20 mm lead
length is only available on capacitors with straight leads (lead configuration ordering code). For nonstandard lead length inquiries, please contact
KEMET.

Bulk packaging lead length availability is dependent uponLead Configuratio andLead Spacing SeeDimension section of this document to
verify availability of a specific lead length option. For nonstandard lead length inquiries, please contact KEMET.
