Mica and PTFE capacitors belong to the subgroup of ceramic capacitors. They feature many benefits, such as high reliable operation, wide temperature range, stability of parameters, low loss and long lifetime. In particular, these devices are suitable for high frequency tuning and compensation. The CDV19FF432GO3 is one of such mica and PTFE capacitors. Here we will discuss its application field and working principle in details.

The CDV19FF432GO3 is a high frequency, low loss ceramic chip capacitor. It shows excellent capacitance stability at various temperature, thermal shock and moisture conditions. It features a high insulation resistance and a long working life. It is widely used for AC and DC filtering applications, high frequency tuning and compensation, as well as EMI-RFI suppression.

This mica and PTFE device operates in a wide frequency range, from 700kHz to 1GHz. It can remain non-polarity, so it is ideal for coupling. Its capacitance range is from 2.2pF to 10pF and its small size makes it easy to use in portable devices and mobile phones. This capacitor is also resistant to common environmental factors such as humidity and could even endure shock and vibration.

The working principle of CDV19FF432GO3 is based on mica and PTFE dielectrics. The ceramic base of the capacitor contains several layers of PTFE and several layers of mica. These layers act as dielectric between the conductors and the ceramic base plate. This sandwich helps to reduce dissipation factor and improves insulation resistance. The mica prevents the movement of the dielectric due to an electric field, so the capacitance remains constant. The PTFE encapsulation makes the chip stronger and protect it from environmental damages.

To sum up, the CDV19FF432GO3 is a mica and PTFE chip capacitor with excellent performance characteristics. It offers low loss operation in a wide frequency range and has excellent insulation resistance. It is suitable for various applications such as high frequency tuning and compensation, filtering applications, EMI-RFI suppression and coupling. Moreover, its low dissipation factor and long working lifetime make it reliable for long-term use.
