CMR03E560GOCR

Mica and PTFE capacitors are widely used in RF, microwave and other high-power applications due to their superior dielectric properties. The CMR03E560GOCR is a high performance mica and PTFE capacitor designed to extend the upper frequency limit of an RF circuit. It is rated for use up to 18GHz and features a low ESR of 51mΩ. The capacitor is constructed from a PTFE dielectric material with a mica substrate and offers extremely low losses when compared to traditional ceramic or plastic capacitors.

In an RF circuit, CMR03E560GOCR capacitors are used to block or pass signals in the frequency range they are designed for. By adding such capacitors in a circuit, the frequency response of the circuit can be precisely controlled as the capacitor’s reactance reaches a maximum in its upper design frequency range. As a result, the CMR03E560GOCR capacitors are widely used in the frequency-selective networks of communication equipment, including low noise amplifiers, filters, switches, converters, etc.

The CMR03E560GOCR capacitor is composed of a ceramic body and a pair of metalized plates. The metalized plates are coated with a conducting material such as silver or gold, and when polarized, an electric field is created between them. Since the ceramic material has a high dielectric constant, very little electric field is required to create a specific capacitance. In addition, the ceramic material also keeps the electric field very uniform, reducing ESR and providing a very stable capacitor. As a result the capacitor is able to function with very low signal losses even at high frequencies.

The working principle of the CMR03E560GOCR capacitor is simple but effective. When a voltage is applied, an electric charge is placed on the plates, creating an electric field between them. This electric field provides a capacitance that follows the equation: capacitance is equal to the permittivity of the dielectric material multiplied by the surface area of the plates divided by their distance.

In summary, the CMR03E560GOCR is an ideal capacitor for use in RF, microwave or high-power applications due to its excellent dielectric properties, high frequency capability, and low ESR. The capacitor is constructed of a PTFE dielectric material, with a mica substrate, and its working principle is based on the permittivity of the dielectric material, the area of the plates, and their distance.
