Mica and PTFE Capacitors

Mica and PTFE capacitors are capacitors made up of two capacitance plates formed by the combination of mica and metal foil. The metallic foil is usually made up of a very thin layer of metal that is then inserted between the dielectric layers. The capacitor’s plate separator, or insulator, is formed by a very thin layer of mica and a slightly thicker layer of PTFE. The advantage to using mica and PTFE capacitors is that they have very high self-resistance, which helps to make them very reliable and efficient.

The CD17ED430JO3F capacitor is a typical mica & PTFE capacitor structure. It is a surface mounted device that conforms to RoHS and REACH environmental regulations. This capacitor is typically used in high frequency, high voltage applications such as mobile communication systems, high-end solid-state systems, medical chart recorders, TV receivers, and TV broadcast systems. This capacitor is highly reliable due to its low internal temperature coefficient, high voltage capability, and low frequency dielectric absorption.

The working principle of this capacitor is based on a concentration of static electric charges that are stored between two metal plates. The static electric charge stored in this capacitor can be released as an electrical current when the circuit is triggered. Once the current is released, the electron flow circulates around the circuit that it is connected to, effectively completing the circuit. Thus, the mica & PTFE capacitor acts as a conductor and enables the current to flow between the two capacitance plates.

The primary advantages of using mica and PTFE capacitors is the combination of its low loss, low leakage current, high withstand voltage, and excellent dielectric properties. These properties make them ideal in many different applications and are found in a variety of products such as mobile phones, televisions, radios, military applications, and many consumer electronics. Manufacturing processes for these capacitors are highly consistent and are tailored to ensure reliable high frequency, high voltage performance.

The CD17ED430JO3F capacitor is a specific type of capacitor that is designed for high frequency, high voltage applications. Its structure facilitates a low temperature coefficient, high voltage capability, and low frequency dielectric absorption. Its combination of mica and PTFE metal foil provides superior capacitance properties that are highly reliable and efficient. As a result, this capacitor is used in a variety of applications ranging from medical equipment to mobile phones.
