6 FAQs about [Use of safety capacitors]

What is the importance of Safety capacitors in power electronic applications?

This article based on Knowles Precision Devices blog elaborates on importance of safety capacitors in power electronic applications. Safety capacitors are designed to mitigate the effects of transient voltages and interference in electrical and electronic circuits, especially high-voltage applications, ensuring their safe operation.

Which devices need safety capacitors?

Even everyday devices need safety capacitors: modems and other telecoms equipment, AC-DC power supplies, power distribution switchgear, and electric vehicles (EVs) and other automotive applications.

What standards are used to define safety capacitors?

As with many safety-critical devices, varying standards and respective classifications are used to indicate the capabilities and threshold of safety capacitors. There are a variety of standards that are used to define safety capacitors such as IEC 60384-14, UL 1414, UL 1283, CAN/CSA C22.2 No.1, and CAN/CSA 384-14.

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.

Can safety capacitors be used in a DC/DC converter?

More recently, capacitively-coupled DC/DC converter designs have appeared that use safety capacitors to provide input-to-output isolation. And safety MLCCs are finding use in antenna coupling applications. Since capacitors in EMI filters are connected to ac power lines, these capacitors can fail due to over-voltages and transients.

What are the different types of Safety capacitors?

Two common types that can fit the role of safety capacitors are multilayer ceramic capacitors (MLCCs) and plastic film capacitors. Each has its benefits depending on the specific application. Some characteristics to consider when choosing between capacitors include the following:
