What is the difference between Y1 and Y2 capacitors?

The difference between Y1 and Y2 capacitors is the maximum isolation voltage of the component. Y2 capacitors can be used for barriers with up to 1500VAC test voltage, Y1 rated capacitors can be used for barriers up to 3000VAC test voltage.

What is a Y2 capacitor?

Y-capacitors, which are used to bridge operational insulation, are classified as Y1, Y2, Y3 or Y4 according to type of bridged insulation as well as AC and peak voltage ratings. Y2 capacitors have 150 to 300VAC ratings and a peak test voltage of 5kV.

What are X2 and Y2 capacitors?

Class X and Y capacitors are also given a number to represent their impulse test rating. The most common are X1 (tested to 4,000 volts), X2 (2,500 volts), Y1 (8,000 volts) and Y2 (5,000 volts). references. Just Radios: ABC’s Of Safety Capacitors For Tubes.

How does Y capacitor work?

How Y Capacitor Works? The working principle of a Y Capacitor is very simple. We know, the reactance of the capacitor decrease with the increase of frequency. So, when electromagnetic interference occurs, a very high frequency of unwanted signal or current is produced.

What does X2 mean on a capacitor?

Class X and Y capacitors are also given a number to represent their impulse test rating. The most common are X1 (tested to 4,000 volts), X2 (2,500 volts), Y1 (8,000 volts) and Y2 (5,000 volts).

What is the purpose of X2 capacitor?

Class-X and Class-Y capacitors are safety-certified capacitors generally designed and used in AC line filtering in many electronic device applications. These safety capacitors are also known by other names, including EMI/RFI suppression capacitors and AC line filter safety capacitors.

What is the voltage rating of a Y1 capacitor?

Class X and Y capacitors are also given a number to represent their impulse test rating. The most common are X1 (tested to 4,000 volts), X2 (2,500 volts), Y1 (8,000 volts) and Y2 (5,000 volts).

What is the difference between y2 and X safety capacitors?

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.

What are the different types of X1 capacitors?

X1, X2, Y1, & Y2 Classifications. Class X and Y capacitors are also given a number to represent their impulse test rating. The most common are X1 (tested to 4,000 volts), X2 (2,500 volts), Y1 (8,000 volts) and Y2 (5,000 volts).

What are the Class X and Class Y capacitors?

One specific use of capacitors is in power line filtering in many appliances and electronic devices. Capacitors used in these applications are categorized as being either Class X or Class Y, and then rated by their tested voltage, such as X1 or Y2.
