Mica and PTFE Capacitors: CMR05E680JODM Application Field and Working Principle
Mica and PTFE capacitors, also known as high-frequency capacitors or chip capacitors, are passive components capable of storing energy within an electrical circuit. They are commonly used in high-frequency applications, such as radio-frequency equipment, television broadcasting, and cellular communication.
The CMR05E680JODM high-frequency capacitor is a surface-mountable, through-hole device that was designed by Shanghai Jolem Electronics Technology Co., Ltd. This capacitor is particularly suited to applications such as radio, broadcasting, navigation and satellite signal transmission, as well as television encoding and decoding. It is also suitable for use in power supplies, buffer couplers, and audio systems.
The CMR05E 680JODM is made from an organic, non-combustible substrate material, allowing it to be used in applications where a less flammable material would be preferable. The device has a wide operating temperature range from -40 degrees to +85 degrees Celsius. Additionally, the capacitor has an impressive lifetime of 50,000 hours.
The CMR05E680JODM uses a mica substrate with a PTFE (polytetrafluoroethylene) dielectric. These two materials, due to their high dielectric constant and low temperature coefficient of capacitance, allow it to maintain an excellent capacitance stability across a wide frequency range and temperature range. As a result, the capacitor can be used in applications with varying demands, such as communication systems for aerospace and automotive applications.
In terms of working principle, the CMR05E680JODM stores energy and current in an electrical circuit by accumulating electric charge on two different electrodes separated by a dielectric (insulating) material. When the capacitor is initially switched on, electrons are collected on the negative plate, resulting in a negative charge. Similarly, when the switch is opened, electrons will start to move away from the negative plate to the positive one and inversely.
The CMR05E680JODM features low ESR and ESL, allowing it to support a high frequency signal such as VHF band or higher-frequency signals such as UHF band and above. The capacitor also has a high voltage tolerance, enabling it to withstand a wide range of voltages without failing. This can be especially beneficial when used in communication systems, which often require high-tolerance capacitors due to their unpredictable and ever-changing voltage.
In summary, the CMR05E680JODM is a surface-mountable, through-hole high-frequency capacitor that utilizes the combination of mica substrates and PTFE dielectric materials to produce a highly stable and reliable component. Its high operating temperature range, high voltage tolerance, and low ESR and ESL levels make it an ideal choice for high-frequency applications, such as radio-frequency equipment, television broadcasting, satellite signal transmission, and cellular communication.
