Mica and polytetrafluoroethylene (PTFE) capacitors represent an important capacitance category for use in various circuit designs. CD30FC273JO3 is one of most commonly used types, which, especially suitable for high temperature purpose with good quality as well as small case size. This article will discuss the application field and working principle of CD30FC273JO3.

Types of Mica and PTFE Capacitors

Mica and PTFE capacitors are available as disc, film, chip, and radial lead types. Film is one of the most common types of capacitors with lower capacitance values. Disc capacitors, also known as ceramic dielectric capacitors, offer higher capacitance values. Chip capacitors work differently and offer a range of capacitance values. Radial leaded capacitors allow for easy mounting and can be used for any type of application.

Characteristics

These capacitors share some important characteristics. They are small, light, and have low energy losses, high temperature stability, and low temperature coefficient of capacitance. They provide great dielectric strength and can work well at frequencies in the tens of MHz. They offer excellent pulse handling, good cost-effectiveness, and wide range of capacitance values.

CD30FC273JO3 Application Field and Working Principle

CD30FC273JO3 with rated capacitance of 0.27uF, is a high-temperature-resistant capacitor specifically designed for power electronics applications. The main application field for CD30FC273JO3 capacitors includes power supplies, motor control circuits, and other electronic merchandise experiencing high temperature or humid environments. This type of capacitor is especially used for DC-DC converters operating at high temperatures.

The working principle of CD30FC273JO3 is based on the principle of capacitance: when two conductive plates are separated by a non-conductive dielectric material, an electric charge is produced when a voltage is applied to the plates. As the voltage across the plates is increased, the amount of electric charge held by the capacitor increases. The capacitance is then measured in Farads.

The unique advantage of the CD30FC273JO3 is its high temperature performance, which enables it to work well in power electronics applications. It also offers good insulation characteristics between the plates and is resistant to changes in environmental conditions.

Conclusion

Mica and PTFE capacitors such as CD30FC273JO3 are available in a wide range of resistance and capacitance values. These capacitors offer excellent temperature stability, low energy losses, high reliability, and good pulse handling. They are widely used in power supplies, motor control circuits and other applications operating at high temperatures.
