Overview

KEMET’s C700 encapsulated radial leaded ceramic disc

capacitors are specifically designed for interferencesuppression

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.

Safety Certified Capacitors are classified as either X and/or

Y capacitors. Class X capacitors are primarily used in lineto-

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.

With a working voltage of 440/400 VAC in line-to-line

(Class X) and 300/250 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.
