Radial Leaded Ceramic Disc Capacitors
Safety Standard Recognized, 900 Series, Encapsulated,
AC Type, X1 440 VAC/Y2 300 VAC (Industrial Grade)
Overview
KEMET’s 900 Series encapsulated radial leaded ceramic
disc capacitors are specifically designed for interference-
suppression AC line filtering applications. Having interna-
tionally recognized safety certifications, these capacitors
are well-suited for applications that require keeping poten-
tially disruptive or damaging line transients and EMI out
of susceptible equipment. They are also an ideal solution
in situations where there is a need to suppress line distur-
bances at the source.
With a working voltage of 440 VAC in line-to-line (Class X)
and 300 VAC in line-to-ground (Class Y) applications, these
safety capacitors meet the impulse test criteria outlined in
IEC Standard 60384. Meeting subclass X1 and Y2 require-
ments, these devices are certified to withstand impulses up
to 4 KV (X1) and 5 KV (Y2) respectively. These encapsulated
devices also meet the flame test requirements outlined in UL
Standard 94V–0.
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 application 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.

1 Due to a high risk of arcing, "Inside Kink" lead configuration cannot be combined with the 5 mm lead spacing option. The "Inside Kink" option is only
available on capacitors with lead spacing of 7.5 mm or greater. A potential for arcing may exist when combining the "Inside Kink" 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.
2 Capacitor body diameter will limit available lead spacing and packaging options. See "Dimensions" and "Product Ordering Codes and Ratings" sections
of this document to determine availability.
3 "Vertical Kink", "Outside Kink" and "Inside Kink" 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 "A"). For nonstandard lead length inquiries, please contact
KEMET.
4 Bulk packaging lead length availability is dependent upon "Lead Configuration" and "Lead Spacing." See "Dimensions" section of this document to
verify availability of a specific lead length option. For nonstandard lead length inquiries, please contact KEMET.
