KEMET’s CAS surface mount 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. 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.
