Mica and PTFE Capacitors

Capacitors are essential components in modern electronic systems. They store energy and enable a variety of functions such as filtering, timing, and signal modulation. The two main types of capacitors used in electronic systems are mica and polytetrafluoroethylene (PTFE). CD10ED390GO3 is a mica and PTFE capacitor manufactured by Great Wall Electronics. This device has a radial lead and a snap-in mounting. CD10ED390GO3 is a 10µF device rated at 10V DC voltage with a 125°C maximum operating temperature. It is approved by IEC60384-14 and UL, VDE, and RoHS.

Application field of CD10ED390GO3

CD10ED390GO3 capacitor is suitable for general purpose, reliable, and snappy applications such as power supplies, automotive electronics, military or medical devices. It is generally used for filtering, timing, and signal modulation applications. The capacitor is also ideal for audio equipment, lighting control, motor drive, switch mode power supply, and telecommunications.

Working Principle of CD10ED390GO3

The operation of CD10ED390GO3 involves two key components: the mica and PTFE dielectrics. The mica dielectric has an ideal dielectric constant of 22 and is surrounded by two pieces of metal foil (anode and cathode) which have been chemically treated for improved performance. The PTFE dielectric is formed between the metal foil and the outermost layer of mica, which creates an air gap between the two dielectrics. When a voltage is applied to the capacitor an electrical field is created between the anode and cathode. This field causes the excess electrical charge to be transferred from one side to the other, storing energy. The stored energy is then released back when the voltage applied to the capacitor is less than the voltage stored in it. This is the basic principle behind how CD10ED390GO3 works.

Advantages of CD10ED390GO3

CD10ED390GO3 capacitors have a number of advantages, making them an attractive option for many electronic systems. These include: - High dielectric strength: The mica and PTFE dielectrics are engineered to provide a superior dielectric strength, which is important for maintaining the performance of the capacitor. - Excellent temperature stability: The dielectric materials used in CD10ED390GO3 enable the capacitor to have an excellent temperature stability, making it ideal for applications that require reliability in a wide range of temperatures. - Low leakage current: The mica and PTFE used in the device provide excellent low leakage current performance, which is ideal for applications that require low power consumption. - High mechanical strength: The snap-in mounting nature of the CD10ED390GO3 provides a robust and reliable physical assembly for the capacitor, making it resistant to shock and vibration.
