What is a safety capacitor?

Capacitors are essential passive components used in every modern circuit and electronics application for smoothing and filtering power lines and for bypassing signals. In AC/DC EMC filter applications, two special classes of capacitors – Class-X and Class-Y – are used to filter AC power-source noise and are commonly referred to “safety capacitors”.

What are safety X and Y capacitors?

Y-class safety capacitors classification Safety X and Y capacitors are typically ceramic discs, multilayer ceramic, or plastic film capacitors in leaded or SMD packages. Keeping up with classifications and certifications, knowing where they should go and which are interchangeable, can be very confusing for designers.

Why do I need a safety capacitor certification?

Certifications are also important to confirm IEC 60384-14.4 safety tests. Safety capacitors can isolate the input and/or output if it is referenced back to a non-isolated buck on mains voltages, especially if a user has access to the connections or interface.

What is a Y-class safety capacitor?

Y-class capacitors are used in “line-to-ground” applications where failure could lead to an electrical shock. It is also divided into sub-classes by their AC voltage and peak surge voltage ratings. See Table 2. Table 2. Y-class safety capacitors classification

What are Class X and Class Y capacitors?

In AC/DC EMC filter applications, two special classes of capacitors – Class-X and Class-Y – are used to filter AC power-source noise and are commonly referred to “safety capacitors”. Learn about where to use Class-X or Class-Y capacitors and what makes these safety capacitors critical for modern circuit design.

What is a ceramic capacitor used for?

Ceramic capacitors are more often used for antenna coupling, primary and secondary coupling such as switching power supplies, line disturbance suppression such as high-speed switching controls such as motor control, relays, switching power supplies, and inverters.
