Mica and PTFE Capacitors are widely used in many electronic applications including audio, industrial, military and medical applications. CDV19FF332FO3F, also known as the Murata M180 capacitors, are specifically designed for high frequency applications with stability and robustness. In terms of capacitor types, these capacitors belong to the class of Automotive Grade Chip Capacitors. CDV19FF332FO3F capacitors are thin film capacitors with a dielectric material of polyethylene (PTFE). Being automotive grade, they are designed to have wide temperature range (−55°C to +125°C), high insulation resistance (up to 1,000 MΩ) and a low dissipation factor.

The typical application field for CDV19FF332FO3F capacitors is up to 500 MHz. Due to their high stable performance, they are mainly used in power supplies, DC/DC converters, up converters, high frequency switching supplies, and microwave circuits. CMOS circuits and LCD operating circuits are applications for these kinds of extremely reliable components as well.

The working principle of these components relies on the combination of two distinct layers of metal, that act like plates, being separated by a dielectric material. As with the CDV19FF332FO3F capacitor, these plates are separated by a polyethylene or PTFE dielectric. This principle is also applicable to Electrolytic, Ceramic, Tantalum and other constructions of capacitors, as each relies on the same physical principle in order to function correctly.

The PTFE and Mica is used as a dielectric material providing the necessary insulation between the plates. When the capacitor is connected in an electrical circuit, an electric field is created and causes the surface of the plates to become ‘polarized’, forming a dipole layer between the two plates. This ‘dipole layer’ acts as a capacitor with specific characteristics, like capacitance, insulation resistance and other electrical values.

CDV19FF332FO3F capacitors offer low ESR and low ESI, making them ideal for use in high frequency applications, as well as providing far wider temperature ranges in comparison to conventional dielectric capacitors. The presence of the PTFE layer in these components also increases the insulation resistance property of the device, making it very reliable under high-frequency switching conditions.

These types of capacitors are also suitable for use in surface mount devices because of their small size. The thinner the thickness of the plastic film, the lower the insulation resistance. This means that these capacitors can be mounted on chips and other components with low space consumption.

Overall, CDV19FF332FO3F are Mica and PTFE capacitors created specifically for applications requiring stability and robustness in high frequency frequency circuits like power supplies, DC/DC converters, up converters, high frequency switching supplies and microwave circuits with operating temperature from −55°C to +125°C. They offer low ESR and low ESI, making it suitable for high frequency applications with the presence of a PTFE dielectric layer that increases the insulation resistance. These capacitors are also suitable for surface mount applications due to their small size.
