Film capacitors, also known as plastic film capacitors, are non-metallic capacitors that use various plastic films as the dielectric medium. Film capacitors are available in a wide range of values, styles, and ratings, making them a useful component to multiple electronic applications. The MKP386M510085JT7 is a series of film capacitors that are specifically designed for high-temperature applications and have been rated for operation from -55°C to +155°C. This series of capacitors is available in three different capacitance values and tolerance capabilities ranging from 1 nF to 10000 nF, and the capacitance tolerance range is from -10% to +15%. Additionally, the MKP386M510085JT7 are able to sustain a rated voltage of 1000V and have a long lifespan of up to 10,000 hours.

The MKP386M510085JT7 series of film capacitors are commonly used in telecommunications and other high-temperature electronic applications. These capacitors are ideal for applications such as snubber circuits, power supply systems, power conversion modules, amplifiers, and more. Additionally, the MKP386M510085JT7 is often employed in high-frequency switching power supplies and AC power circuits for its superior performance in temperature and frequency.

The working principle of film capacitor is based on the electrostatic principle, which states that when two plates or electrodes of a capacitor are charged with opposite charges the electric field that is created between them creates an opposing force to the current. When applying voltage to the capacitor, the dielectric material (plastic film) between the electrodes will become polarized and create a charge separation, allowing energy to be stored between the two plates. This energy will remain stored in the capacitor until the voltage is removed, at which point it will be discharged as electric current.

The MKP386M510085JT7 series utilizes a polypropylene film and aluminum foil as the dielectric in order to provide superior capacitance stability over frequency and temperature. The use of polypropylene film allows these capacitors to have an extended temperature range and provide reliable operation at high-temperature environments. Additionally, the use of aluminum foil enables the capacitors to have a lower ESR (equivalent series resistance) and ESL (equivalent series inductance). This allows for superior filtering performance and noise suppression due to its low internal impedance.

The MKP386M510085JT7 is designed for applications that require a high-temperature and reliable performance over frequency. Its low inductance and ESR make it an ideal choice for high-frequency switching power supplies and AC power circuits, as well as snubber circuits, power supply systems, and amplifiers. Additionally, its high capacitance stability over temperature make it suitable for components in telecommunications and other high-temperature applications.
