Temperature and Voltage Variation of Ceramic Capacitors, or
The reality of modern, small form-factor ceramic capacitors is a good reminder to always read the data sheet. This tutorial explains how ceramic capacitor type designations, such as X7R and Y5V, imply nothing about voltage coefficients. Engineers must check the data to know, really know, how a specific capacitor will perform under voltage.
Understanding Capacitor Types and Characteristics | DigiKey
Ceramic capacitors. These capacitors use a ceramic dielectric. There are two classes of ceramic capacitors, Class 1 and Class 2. Class 1 is based on para-electric ceramics like titanium dioxide. Ceramic capacitors in this class have a high level of stability, good temperature coefficient of capacitance, and low loss.

In mechanically controlled variable capacitors, the distance between the plates, or the amount of plate surface area which overlaps, can be changed. The most common form arranges a group of semicircular metal plates on a rotary axis ("rotor") that are positioned in the gaps between a set of stationary plates ("stator") so that the area of overlap can be changed by rotating the axi…

A ceramic capacitor is a fixed-value capacitor where the ceramic material acts as the dielectric. It is constructed of two or more alternating layers of ceramic and a metal layer acting as the electrodes. The composition of the ceramic material defines the electrical behavior and therefore applications. Ceramic capacitors are divided into two application classes:
