What is X2 safety capacitor?
These X2 caps offer self-healing properties and a polypropylene dielectric. They have a capacitance range of 5.6nF to 6.8µF with ±10% capacitance tolerance. Typical applications for Würth Elektronik X2 Safety Class Film Capacitors are safety, filtering, interference suppression, and power supplies.
What are X2 and Y2 capacitors?
This is because, although an X2-type capacitor would work and filter noise sufficiently, it would not meet the line-to-ground safety standards. 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.
What is X1 Y1 capacitor?
Background. An X1 class ceramic capacitor is used for interphase with a primary power supply. It can also be used as a Y1 class capacitor for connecting between an AC power line and ground.
What are line capacitors?
Transmission line conductors constitute a capacitor between them. The conductors of the transmission line act as a parallel plate of the capacitor and the air is just like a dielectric medium between them. The capacitance of a line gives rise to the leading current between the conductors.
What is the purpose of X2 capacitor?
Because of all safety features, the X2 capacitor is a popular choice to be used as a capacitive divider in low-power consuming appliances. The capacitive reactance of a capacitor is used to reduce the mains voltage to a lower voltage. Such an application is called capacitive power supply or a capacitive dropper.
What is Y2 capacitor?
The compact Y2 EMI suppression capacitors from EPCOS is connected to protective ground between the neutral conductor and phase to suppress high-frequency interference and transients, they protect the equipment and allow it to operate reliably. Typical applications include power supplies and household appliances.
What are Y2 capacitors?
Y2 is a basic single-insulated Y capacitor that is used to bridge the primary side to protect the earth, the FG line. Safety capacitance refers to the situation where the capacitor fails and does not endanger personal safety. Accoding to IEC 60384-14, capacitors are divided into X capacitors and Y capacitors.
What is suppressor capacitor?
Also known as EMI suppression capacitors, these capacitors reduce the amount of electro magnetic interference (EMI) generated in equipment. They protect against surges and can be used for AC filtering.
What are X2 capacitors used for?
EN 60384-14 defines sub-classifications for both types. X1 capacitors are used for high pulse applications, while X2 and X3 types are used for general-purpose applications with different peak pulse operating voltages and peak value surge voltages.
What is a DC link capacitor?
In electric vehicle applications, the DC link capacitor is used as a load-balancing energy storage device. The capacitor is placed parallel to the battery, which maintains a solid voltage across the inverter. The device helps protect the inverter network from momentary voltage spikes, surges and EMI.
What are XY capacitors?
X/Y capacitors are used on the input, or AC side, of the power supply to provide EMI filtering. The capacitors must also be able to handle power surges, as the capacitors bridge the isolation barrier. AC/DC power supplies commonly use X1/Y2 safety capacitors.
