Mica and PTFE Capacitors: MC12FA251F-TF Application Field and Working PrincipleMica and PTFE capacitors have been widely used across a variety of electronic systems due to their long-term dependability, small size, and high energy efficiency. One of the most popular models of Mica and PTFE capacitors is the MC12FA251F-TF, which is an epoxy-encapsulated, hermetically-sealed capacitor with a capacitance of 2.2µF and a voltage rating of 2000Vdc. The frequency range of this capacitor is up to 3kHz, and it has a temperature range of -55°C to 105°C. Moreover, its dielectric is PTFE, which allows for an extremely low ESR.The MC12FA251F-TF is customizable due to its multiple terminal configurations, including radial, axial, SMD, and connector styles. These features make this capacitor an ideal choice for a wide range of applications, such as power supplies, frequency generators, motor control, and telecommunications. In addition, its small size makes it suitable for circuit board layouts that require compact designs.In terms of its working principle, the MC12FA251F-TF capacitor’s primary function is to store energy and to resist the passage of electric current. This function is accomplished by having two or more conducting surfaces separated by a dielectric, which is an insulator. When a voltage is applied to the capacitor, the dielectric creates an electric field between the two conducting surfaces. This electric field stores energy in the form of electrical potential energy. The capacitance of this capacitor depends on the thickness and dielectric constant of the dielectric, as well as on the surface area of the two conducting surfaces.During operation, the capacitor will discharge or reduce its stored energy. This process is known as capacitive charging or discharging and is essential for electronic applications. When the capacitor is charging, current flows from the capacitor terminals. This current is then stored in the electric field between the two conducting surfaces. Eventually, this electric field will reach its maximum potential, which is called the breakdown voltage.The MC12FA251F-TF Mica and PTFE capacitor is a highly reliable and efficient device that offers an excellent selection for countless applications requiring capacitance and voltage. It is the perfect choice for a wide range of digital circuits and systems due to its many features, such as its multiple terminal configurations and exceptionally low ESR. Additionally, its hermetically-sealed epoxy casing allows for greater environmental protection and longevity. With its wide frequency range and temperature range, the MC12FA251F-TF is an indispensable part of various digital systems.
