Radial Through-Hole Ceramic Disc Capacitors
Safety Standard Recognized, 900 Series, Radial Disc,
Encapsulated, X1 400 VAC / Y2 250 VAC (Industrial Grade)
Overview
KEMET’s 900 Series Encapsulated Radial Through-Hole
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
there is a need to suppress line disturbances at the source.
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
it 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.
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 Y2 requirements, 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 94 V–0.

When choosing the Ammo Pack option, please note that the carrier tape pitch dimension is dependent upon the lead spacing dimension of the component. Carrier
tape pitch dimensions are as follows:
15.0 mm for components with a 7.5 mm lead spacing dimension.
25.4 mm for components with a 10.0 mm lead spacing dimension.
