Y Capacitors: Class-Y capacitors, also known as "line-to-ground capacitors" or "line bypass capacitors," offer line-to-ground protection, which generally means that if a failure with the ground occurs, there is a risk for shock. However, Class-Y safety capacitors must meet rigorous specifications, minimizing the chance of electric shock.
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.
(2) Current-limiting capacitors must be non-polar capacitors, and electrolytic capacitors must not be used. And the capacitor withstand voltage must be above 400V. The most ideal capacitor is an oil-filled iron-case capacitor. (3) Safety capacitors can not be used for high power. (4) The safety capacitor step-down is not suitable for dynamic load.
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:
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.
Certified Safety Capacitors are vital components for safety-critical across-the-line and line-to-chassis applications. X-class capacitors are used across the line where failure would not lead to an electrical shock. X-class capacitors are divided into sub-classes by their rated and pulse voltage. See Table 1. Table 1.
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
