Mica and PTFE capacitors are among the most reliable and robust passive components available on the market today. CDV19EF270JO3 is a series of mica and PTFE capacitors offering high level of stability, reliability, as well as high energy efficiency. This particular series of capacitors feature an extremely low ESR and a very low self-resonant frequency. This makes the series ideal for a range of applications, including power supplies, filters, clock buffers, medical and military applications.

The construction of the capacitors in the CDV19EF270JO3 series consists of a thin film of PTFE must be sandwiched between two layers of mica. The PTFE is non-dielectric and highly stable which makes it ideal for these types of capacitors. The high dielectric strength of the PTFE provides higher capacitance stability, higher insulation resistance, and greater energy storage. The mica layers act as insulating and interconnecting layers, providing the necessary low dielectric power in order to meet the high frequency requirements.

The capacitance of the CDV19EF270JO3 series is typically 4µF. The capacitance of these capacitors is very stable with the ESR of the CDV19EF270JO3 series lower than 12mΩ. The PTFE dielectric provides a low ESR for these capacitors, making them ideal for applications that require high energy efficiency and reliable operation. The self-resonant frequency of these capacitors is typically around 200 kHz, which makes them suitable for high-frequency applications.

The CDV19EF270JO3 series of capacitors is ideal for a range of applications, such as power supplies, power converters, switching regulators, computer clock buffers, automotive electronics, medical electronics, and other specialized military applications. The PTFE layers in these capacitors provide excellent stability in high frequency and high temperature environments making them ideal for these types of applications.

The working principle of CDV19EF270JO3 series of capacitors is relatively straightforward. When a voltage is applied to the capacitor, the electric field generated between the two conductive plates causes electric current to flow through the dielectric material. This effectively stores energy in the form of an electric field and allows it to be discharged when the voltage is removed. By controlling the amount of current stored in the capacitor, the capacitance of the CDV19EF270JO3 series can be accurately adjusted to meet the application’s needs.

Overall, the CDV19EF270JO3 series of mica and PTFE capacitors are highly stable, reliable, energy efficient and offer a very low self-resonant frequency. These capabilities make them ideal for a range of specialized applications that require high performance and reliable operation.
