Mica and PTFE CapacitorsMica and PTFE capacitors are becoming increasingly popular in the electronics industry due to their high capacitance, low ESR and excellent reliability. The CD4ED470GO3F is an electronic component designed for use in both low- and high-frequency applications. In this article, we will examine the application field and working principle of the CD4ED470GO3F. The CD4ED470GO3F is a high temperature, high voltage, surface-mount, mica-and-PTFE-based capacitor with a maximum operating temperature of 250 degrees Celsius and a maximum rated voltage of 470V. It is designed for high-voltage, high-frequency applications, such as for power conversion in resonators and level switching in voltage-controlled oscillators. It can also be used in motor drive applications. The capacitor comprises two layers of mica sandwiched between two layers of PTFE insulation material. The mica layers are etched to form individual parallel plates that act as a dielectric between metal electrodes. This allows for a significantly higher capacitance than is possible with conventional capacitors. The mica layers ensure a low loss of dielectric throughout the lifetime of the capacitor. The PTFE layers provide good electrical insulation and further protect against high voltage transients. The CD4ED470GO3F capacitor is built using a co-fire ceramic process, which involves the use of a single sintering step to impart physical properties to the structure of the device. This process allows the capacitor to be made with a high degree of precision and uniformity, which has advantages in terms of performance and reliability. The working principle of the CD4ED470GO3F capacitor is basically the same as that of any other capacitor. In simple terms, it operates by storing electrical energy in the form of an electrostatic field between two conductors, which can then be discharged by providing a suitable path for the current to flow. The level of capacitance depends on the physical size and shape of the capacitor, as well as the material used for the dielectric and electrodes. In conclusion, the CD4ED470GO3F is a high temperature, high voltage, surface-mount capacitor designed for use in both low- and high-frequency applications. Its high capacitance, low ESR and excellent reliability make it suitable for a wide range of applications, including power conversion, resonator circuits, and motor drive applications. Its co-fired ceramic construction further ensures a high degree of precision and uniformity, leading to improved performance and reliability.
