Mica and PTFE capacitors are commonly used in many different applications due to their small size and superior electrical properties. Among them, CD18FD391JO3 is one of the most well-known and widely used capacitors. The CD18FD391JO3 capacitor is an axial-leaded construction in which mica and PTFE are used as dielectric materials to provide excellent insulation performance and reliable temperature stability. This type of capacitor is commonly used in high frequency filtering, audio filtering, pulse shaping, and bypass capacitors.

The working principle of the CD18FD391JO3 is relatively simple. When a voltage is applied across the two terminals of the capacitor, an electric field is created between the two layers of PTFE and mica. The electric field causes electrons to move from one side to another, creating an electric charge. This electric charge is what allows for the capacitor to store energy. As the charge builds up, it is kept separated with the help of the dielectric layers. The amount of charge that can be stored is determined by the capacitance value, which is related to the size of the capacitor.

The CD18FD391JO3 has a relatively small capacitance of 0.1 uF, making it suitable for applications that require high frequency filtering or audio filtering. It is a good choice for pulse shaping and switching applications as well. Additionally, due to its small size, the CD18FD391JO3 is ideal for high density PCB designs.It also provides very good temperature stability and insulation performance, making it a reliable choice for a wide variety of applications.

The CD18FD391JO3 is one of the most reliable and widely used mica and PTFE capacitors on the market. Thanks to its small size and superior electrical properties, it is a great choice for high frequency filtering, pulse shaping, audio filtering, and many other applications. Overall, this type of capacitor is reliable and offers excellent temperature stability and insulation performance.
