Mica and PTFE Capacitors are composed of both mica and PTFE. This combination of materials provides the capacitor with a high-frequency response and Low ESR (Equivalent Series Resistance) characteristics. CD42FD473FO3F are particularly well-suited to temperature sensing applications, due to their high accuracy, stability, and wide operating temperature range.

The CD42FD473FO3F consists of two terminals: the H-Terminal, which is connected to the electrodes on the capacitor, and the K-Terminal, which is connected to the body or ground. The H-Terminal is where electrical energy is input to the capacitor, while the K-Terminal is where electrical energy is discharged. This type of capacitor is known as a polarized capacitor, meaning that both terminals are utilized when driving the capacitor with an external power source.

The operating principle of a CD42FD473FO3F is similar to other types of capacitors. When an electrical signal is applied to the terminals, an electric field is created between them. This electric field will attract and repel ions in the capacitor, resulting in a change in the capacitance of the device. The degree of capacitance change will depend on the voltage applied and the surface area used.

In terms of the application field of the CD42FD473FO3F, these capacitors can be used in temperature sensing applications due to their high stability, accuracy, and wide operating temperature range. Additionally, they can be used in applications requiring high-frequency response and low ESR, typically in applications such as switched mode power supplies or RF-IDs. Due to their low ESR and low inductance, the CD42FD473FO3F are also used in noise-sensitive applications.

Furthermore, CD42FD473FO3F are suitable for use in applications requiring fast response times. This is because the combination of mica and PTFE capacitors offers both a low-loss dielectric and a rapid charging/discharging rate. This makes them well-suited to memory applications, such as semiconductor RAM, where fast operation is essential.

In conclusion, the CD42FD473FO3F are mica and PTFE capacitors, which offer a combination of high accuracy, stability, wide operating temperature range, low ESR, and fast response time. These properties make them suitable for use in temperature sensing applications, switched mode power supply, RF-ID, and noise-sensitive applications.
