Mica and PTFE Capacitors: CD15FC621JO3F Application Field and Working Principle

Mica and PTFE capacitors, also known as polytetrafluoroethylene (PTFE) capacitors, are a type of capacitor commonly used in electronics and electrical engineering applications. CD15FC621JO3F, one specific model of PTFE capacitors, is well known for its superior performance compared to other capacitor materials. This article will discuss the application field and working principle of CD15FC621JO3F capacitors.CD15FC621JO3F capacitors are widely used in high-voltage and/or high-temperature applications due to their high breakdown voltage and exceptional heat resistance. These capacitors have a working voltage of 15kV and a working temperature of 125°C. They can be used in high-power electrical circuits, motor controls, inverters, and other places where high voltage and high temperatures are encountered.The CD15FC621JO3F capacitor utilizes a specific type of PTFE dielectric that exhibits extremely low power losses in the form of dielectric absorption. This effect is often referred to as the "dielectric absorption ratio" and is measured in volts per microfarad. The CD15FC621JO3F capacitor has a dielectric absorption ratio of 0.0025 volts per microfarad, which is significantly lower than other capacitor materials.The working principle of the CD15FC621JO3F capacitor is relatively simple. The dielectric material between the two electrodes (anode and cathode) has a relatively low resistivity, allowing electrons to flow relatively easily. As electrons pass through the dielectric, they are attracted to the electrodes, forming a charge. This charge is capable of storing electrical energy, and is subsequently stored until the capacitor is discharged.The CD15FC621JO3F capacitor offers a number of advantages over other capacitor materials, including higher breakdown voltage, lower losses in the form of dielectric absorption, and superior heat resistance. The physical layout of CD15FC621JO3F capacitors also offers some additional benefits such as superior power handling capability and greater flexibility in terms of component layout.In summary, CD15FC621JO3F capacitors are commonly used in high-voltage and/or high-temperature applications due to their exceptional performance. The dielectric material used in these capacitors exhibits a lower dielectric absorption ratio, resulting in lower power losses. In addition, the physical layout of these capacitors provides superior power handling capability and greater flexibility in terms of component layout.
