Working Principle of CD19FD391FO3

The CD19FD391FO3 capacitor is composed of PTFE and mica. The working principle of the capacitor is the same as that of other capacitors. The capacitor stores energy in the form of an electric field between two conductive plates that are separated by an insulating material. When an alternating voltage is applied to the plates, the capacitor begins to charge and store energy. The capacitance of the capacitor is determined by the distance between the two plates, the size of the capacitive plates, and the dielectric constant of the insulating material.The CD19FD391FO3 capacitor uses mica as the insulating material and PTFE as the conducting plates. Mica has the characteristics of good insulation performance, high temperature resistance, small temperature coefficient, and good thermal stability. In addition, the PTFE used in the capacitor has the characteristics of high dielectric constant, excellent insulation performance, excellent temperature resistance, and long-term reliability.The advantages of the CD19FD391FO3 capacitor is that it can provide a high energy storage capacity, low loss, high stability, good temperature resistance, and long service life. This makes it a reliable and popular choice for most electronic equipment.
