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 and 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.

Ceramic dielectric electrostatic capacitors are dominating the capacitor market in a number of fields:
Largest volume capacitor technology (by far)
Largest value capacitor technology
Smallest dimension discrete components among all passives
High flexibility of design to meet specific requirements such as low ESL / high-frequency operation
Strong presence in both low voltage, low power and high voltage, high power applications
despite all the above benefits, the technology has some limitations that must be understood for the corr

In the RC low-pass filter, the path to the ground goes through a capacitor, which means impedance will decrease with increasing frequency. Therefore, in this circuit, the ratio of the Vi down to the Vo will depend on the values of R and C and the signal’s frequency. With high frequencies, impedance is low, and energy is sent to the ground as Vi is divided. Low frequencies see a higher impedance, sending energy to the output.

Filters that contain one or more capacitor elements with paper, plastic film, or ceramic dielectric combined with one or more inductive elements in the form of ferrites or chokes are called LC filters. Ceramic capacitors used are of feed-through type, where one terminal consists of the casing soldered or screwed to the chassis. Or there are SMD variants.
