Surface Mount Multilayer Ceramic Chip Capacitors (SMD MLCCs)
Safety Certified, CAS, Surface Mount
X1/Y2 250 VAC, X2 250 VAC (Industrial Grade)
Overview
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. 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. Should the capacitor
fail in this application, there is no danger of electric shock
to humans 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 250 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 5 KV (X1/Y2) and 2.5 KV (X2) respectively.

Density Level A: For low-density product applications. Recommended for wave solder applications and provides a wider process window for reflow
solder processes.
Density Level B: For products with a moderate level of component density. Provides a robust solder attachment condition for reflow solder processes.
Density Level C: For high component density product applications. Before adapting the minimum land pattern variations the user should perform
qualification testing based on the conditions outlined in IPC Standard 7351 (IPC–7351).

Soldering Process
Recommended Reflow Soldering Profile
KEMET’s family of surface mount multilayer ceramic capacitors (SMD MLCCs) are compatible with wave (single or dual),
convection, IR or vapor phase reflow techniques. Preheating of these components is recommended to avoid extreme thermal
stress. KEMET's recommended profile conditions for convection and IR reflow reflect the profile conditions of the
IPC/J–STD–020 standard for moisture sensitivity testing. These devices can safely withstand a maximum of three reflow
passes at these conditions.
