What is a high voltage ceramic capacitor?

High voltage ceramic capacitors are particularly suitable for applications requiring a high voltage (from 10 to 150 kV). They achieve very good performance under pulse and discharge conditions. Ceramic capacitors are suitable for such high voltages while reactive current remains low. Various disc types cover a wide range of capacitances and voltages.

Why are ceramic HV capacitors used?

Ceramic HV capacitors are used in coupling and by-passing high frequency circuits where an important reactive power is needed. These applications require: - a high internal resistance - a high dielectric strength together with: - low or moderate losses at working frequencies (from 50 Hz up to a few kHz).

Who makes high voltage capacitors?

High Voltage, Ceramic, Capacitors manufactured by Vishay, a global leader for semiconductors and passive electronic components.

What voltage can a ceramic capacitor withstand?

Power ceramic capacitors can be made to withstand voltages in the range of 2kV up to 100 kV, with a power specified at much higher than 200 volt-amperes. Smaller MLCCs used in printed circuit boards are rated to voltages from only a few volts up to several hundreds of volts, depending on the application.

What are the advantages of ceramic capacitors?

And, stacked capacitors for switch-mode power supply applications are allowing high values in higher voltage ratings – up to 500 V. Ceramics have some serious advantages over tantalum and aluminum types, with lower ESR and leakage, and longer lifetimes. They do have voltage rating limitations – as we will talk about later.

What is a ceramic capacitor?

A ceramic capacitor is a capacitor which uses a ceramic material as the dielectric. The two most common types are multi-layer ceramic capacitors and ceramic disc capacitors. There are two classes of ceramic capacitors available today: class 1 and class 2. Class 1 ceramic capacitors are used where high stability and low losses are required.
