Radial Leaded Ceramic Disc Capacitors
Safety Standard Recognized, 900 Series, Encapsulated,
AH Type, X1 400 VAC/Y1 250 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
internationally recognized safety certifications, these
capacitors are well-suited for applications that require
keeping potentially disruptive or damaging line transients
and EMI out of susceptible equipment. They are also an
ideal solution when needing to suppress line disturbances
at the source.
With a working voltage of 400 VAC in line-to-line (Class X)and
250 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 Y1 requirements,
these devices are certified to withstand impulses up to 4
KV (X1) and 8 KV (Y1) 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 "Vertical Kink" and "Outside Kink" lead configurations cannot be combined with the bulk/20 mm lead length option (WL20). 20 mm lead length is
only available on capacitors ordered with straight leads (lead configuration ordering code "A"). For nonstandard lead length inquiries, please contact
KEMET.
2 Bulk packaging lead length availability is dependent upon "Lead Configuration." See "Dimensions" section of this document to verify availability of a
specific lead length option. For nonstandard lead length inquiries, please contact KEMET.
