Surface Mount Multilayer Ceramic Chip Capacitors (SMD MLCCs) Safety Certified, CAS, Surface Mount X1/Y2 250 VAC, X2 250 VAC (Industrial Grade) Overview KEMETs CAS surface mount safety certified capacitors Safety Certified Capacitors are classified as either X and/or are specifically designed for interference-suppression Y capacitors. Class X capacitors are primarily used in line-to AC line filtering applications. When comparing to radial line (across-the-line) applications. Should the capacitor leaded disc capacitors, the CAS surface mount form fail in this application, there is no danger of electric shock factor provides engineers the ability to miniaturize to humans but could result in a risk of fire. The Class Y their designs with a higher density solution. Having capacitor is primarily used in line-to-ground (line by-pass) internationally recognized safety certifications, these applications. In this application, failure of the capacitor capacitors are well-suited for applications that require could lead to danger of electric shock. keeping potentially disruptive or damaging line transients and EMI out of susceptible equipment. They are also an With a working voltage of 250 VAC in line-to-line (Class ideal solution when needing to suppress line disturbances X) and 250 VAC in line-to-ground (Class Y) applications, at the source. 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. L Y X Y N Metal Enclosure Ground Benefits Applications Safety Certified to IEC 60384-14 Typical applications include: Class X1/Y2, X2 Line-to-line (Class X) filtering 250 VAC rating Line-to-ground (Class Y) filtering 2.5 kV and 5 kV Impulse Voltages Antenna coupling Reliable operation up to 125C Primary and secondary coupling Available in C0G and X7R Dielectrics (switching power supplies) Case sizes 1808, 1812, 2211, and 2220 Line disturbances suppression (motors and motor Capacitance offerings ranging from 3.0 pF to 22 nF controls, relays, switching power supplies, and inverters) Available capacitance tolerances from 0.5 pF to 20% RoHS compliant One world.
