Mica and PTFE capacitors are widely used in a variety of applications, from telecommunications to medical systems to high-voltage power supplies. The CMR04E750FPDR is an available option in this category. This paper will discuss the application field and working principle of CMR04E750FPDR.Application fieldsThe CMR04E750FPDR, which is composed of a mica plate between two layers of PTFE (polytetrafluoroethylene) material, is an inexpensive and reliable option for high voltage power supplies. Its applications include AC-DC power supplies, dc-dc converters, offline converters, telecom applications and high temperature power supplies. CMR0E750FPDR capacitors are often used in high temperature and high voltage environments, allowing for reliable operation under hostile temperature ratings and current carrying capability.Working PrincipleThe working principle of the CMR04E750FPDR capacitor is based on the electrostatic principle. It consists of two conductive plates which are separated by a dielectric material. When a voltage is applied across the capacitor, an electric field is generated between the plates. As the electric field increases, the dielectric material starts to break down and a current flows through the capacitor. The current creates a displacement current, which is proportional to the applied voltage. This displacement current is then used to transfer energy between the capacitor and its environment.The capacitance value of the CMR04E750FPDR is dependent on the distance between the electrodes and the dielectric thickness and materials used. The greater the distance between the electrodes and the thinner the dielectric material, the higher the capacitance value. The CMR04E750FPDR typically has a capacitance range of 0.0014uf to 0.13uf at 100V.The CMR04E750FPDR is also designed to provide a high insulation resistance. The insulation resistance of the capacitor determines the leakage current, which in turn affects the reliability of the capacitor. The higher the insulation resistance, the less current is allowed to leak through the capacitor. The CMR04E750FPDR has an insulation resistance of 350,000Mohm at 1kHz.ConclusionThe CMR04E750FPDR is a reliable and economical choice for high voltage power supplies. It is composed of a mica plate between two layers of PTFE material and has a capacitance range of 0.0014uf to 0.13uf at 100V. The CMR04E750FPDR also has a high insulation resistance of 350,000Mohm at 1kHz, making it ideal for high temperature and high voltage environments.
