Film Capacitors
Film capacitors, sometimes also known as Polyester or Mylar capacitors, are power capacitor types that are widely used due to their good electrical characteristics and reliability. These capacitors use thin, insulating film layers, usually polyester, as their dielectric material and are constructed by wrapping the film around electrodes. The electrodes are typically metal plates made of aluminum or tantalum.
The MKP386M522070JT1 is a type of film capacitor that provides a high capacitance and low impedance. It features a reliability level of 8 hours at 125°C for rated voltage (VS) and capacitance, making this type of capacitor suitable for use in power supply equipment, medical equipment and other large-scale ultra-high voltage applications.
Working Principle
The MKP386M522070JT1 utilizes the same principle as other film capacitors, which is the ability of a thin insulating film to store electrical energy in the form of a charge. This capacitor uses a voltage-stabilized electrodes as its base and a thin film of polyester as the dielectric material, which is wrapped between the electrodes. When a voltage is applied to the capacitor, electrical charges are stored on the dielectric material, which creates an electrical field between the electrodes.
The MKP386M522070JT1 offers a high capacitance and low impedance, making it a reliable choice for large-scale ultra-high voltage applications and power supplies. It has a rated voltage (VS) of 400 VDC and a maximum operating temperature of 105°C, making it suitable for a variety of applications.
Application Field
The MKP386M522070JT1 is suitable for use in power supply equipment, medical equipment and other large-scale ultra-high voltage applications. The ultra-high voltage capabilities of this film capacitor make it an ideal choice for applications that require high power and reliability. This type of capacitor is also well-suited for switchmode power supplies, as its low impedance and high capacitance make it capable of quickly charging and discharging.
