6 FAQs about [How to use safety capacitors]

What is a safety capacitor?

One of these techniques is the use of so-called safety capacitors, also known as Class X and Class Y capacitors. These capacitors are not special or unique. Just like a decoupling capacitor, the term “safety” refers to the function and placement of the capacitor, not to a specific type of capacitor.

What are x & y safety capacitors?

X and Y safety capacitors filter AC signals and reduce EMI, so they are directly connected to hazardous AC mains voltages and must be certified as "safety capacitors" to ensure safe operation under these conditions. There are various types of safety capacitors used in safety filter circuits.

How do I choose a Class X & Y safety capacitor?

To be clear, you should select your Class-X and Class-Y capacitors according to your design's purpose and requirements. Whereas X2 and Y2 caps are appropriate for household applications, X1 and Y1 safety capacitors are used in industrial settings.

What is the capacitance requirement for a safety capacitor?

The capacitance requirement for this connection is that the safety capacitor’s value must be much larger than the parasitic winding capacitance. This usually means a Class Y capacitor with 1 nF to 1 uF will work, depending on the frequency range required to bypass to the primary side of the system.

Why do I need a safety capacitor certification?

Certifications are also important to confirm IEC 60384-14.4 safety tests. Safety capacitors can be used to 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 y2 safety capacitor?

Y2 safety capacitors are more robust, are able to withstand higher peak impulse voltages, and are designed to fail open as opposed to failing short. There are also safety caps that combine aspects of X and Y types, such that they have met both X and Y safety requirements and standards.
