MC12FA680J-T

Mica capacitors are a type of capacitor in which mica (insulating material) is used as the dielectric. They are available in both fixed and variable capacitance grades. PTFE capacitors on the other hand are capacitors that use polytetrafluoroethylene (PTFE) as the dielectric. They are widely used in high-frequency circuits such as satellite communication systems and wireless communication.

The MC12FA680J-T is a multi-layer metallized polyester (MEP) mica capacitor. It is designed for demanding telecommunications applications, particularly high-voltage power supplies. The MC12FA680J-T is capable of withstanding 1.2kVdc operating voltage and is suitable for a variety of applications including EMI filtering, wave-shaping oscillation networks, compensation of mismatched impedances, and timing circuits.The MC12FA680J-T is constructed from multiple layers of mica and metallized electrodes. Its mica dielectric and metallized electrodes are coated with PTFE, which provides superior insulation and mechanical properties when compared to other capacitors. The MC12FA680J-T capacitor is a fixed capacitance device and utilizes a varistor-like effect in order to maintain its capacitance over time and temperature.The working principle of the MC12FA680J-T capacitor is based on the inverse conduction of electrons between two opposite electrodes, forming a polarized capacitor. When a potential is applied across the electrodes, electric field lines form between the two electrodes, which store charge within the dielectric medium (mica) and correspond to the capacitance of the device. The electric field lines induce an internal polarization, resulting in a large dielectric strength and a low distortion factor.The MC12FA680J-T capacitor has been designed to provide superior performance when compared to other conventional multilayer ceramic and tantalum capacitors. Its PTFE coating provides superior insulation and mechanical protection, as well as improved frequency response and surface mountability. Additionally, the MC12FA680J-T capacitor has superior long-term stability, low- and high-temperature capacitance retention, and low dissipation factor.Overall, the MC12FA680J-T capacitor has a wide variety of applications and offers a number of advantages. Its top-level performance and wide range of features make it the ideal choice for high-voltage power supplies in telecommunications applications.
