KEMET’s internationally recognized safety certified capacitors are specifically developed for interference suppression AC line filtering applications. These capacitors are designed to keep potentially disruptive or damaging line transients and EMI out of susceptible equipment. They are also an ideal solution for suppressing line disturbances at the source.
All safety standard recognized 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 bypass) applications. In this application, failure of the capacitor could lead to danger of electric shock.
Product Selection
Ceramic
KEMET’s Ceramic surface mount (SMD) safety certified capacitors are specifically designed for interference-suppression AC line filtering applications. When comparing to radial leaded disc capacitors, the CAS surface mount form factor provides engineers the ability to miniaturize their designs with a higher density solution. 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.

Ceramic Disc
KEMET’s 900 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.
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.
