Film Capacitors

Film capacitors, also known as polyethylene terephthalate (PET) film capacitors, metallized plastic film capacitors, or parallel-metallized film capacitors, are an important component in power electronics. This type of capacitor is especially important for designs due to its excellent AC characteristics, long product lifetime, high Capacitance and high dielectric strength. It also has excellent stability and temperature characteristics, excellent tolerance, and low ESR – making it an optimal choice for demanding applications for high power frequency conversion and power regulating applications.

MKP385333085JF02W0 Application Field & Working Principle

The MKP385333085JF02W0 is a film capacitor used for many demanding applications. It offers high capacitance, low ESR, high current accuracy and high operating temperature range, making it suitable for many high-power applications in a wide variety of industries such as automotive, digital audio/video, aerospace, defense, and consumer electronics.

The working principle of the MKP385333085JF02W0 can be categorized into two main components: the film layer and the electrodes. The film layer provides the capacitance by acting as an insulator between the two electrodes. The electrodes are usually made of metalized polyethylene terephthalate (PET) and the electrodes act as the electrical charge carriers. When a voltage is applied to the film capacitor, charge is acquired in one electrode and stored in the other electrode. This creates a charge differential between the two electrodes that can be used to perform various functions, such as filtering or buffering signals.

The MKP385333085JF02W0 is used in many applications such as DC power supply filters, energy storage devices, audio/video signal buffering, and high-frequency signal filtering. It is also used for some medical applications like ECG or EEG applications, due to its excellent charge stability and good heat dissipation capability.

The MKP385333085JF02W0 has a capacitor value of 3.5 µF and a working voltage of 85V. It has a maximum operating temperature of 105°C and provides a maximum ripple of 8mV. Furthermore, it has an effective series resistance (ESR) of 0.02W, making it suitable for high frequency applications.

It is important to determine the correct operating conditions for the MKP385333085JF02W0 to ensure optimal performance. In order to avoid any overload on the capacitor, the voltage across the capacitor should not exceed the specified working voltage. The temperature should also be kept within the specified range so as not to cause any thermal runaway. Additionally, the operating frequency should be kept at a certain range to prevent resonance.

In conclusion, the MKP385333085JF02W0 is an excellent choice for demanding applications in a wide variety of industries. Its excellent AC characteristics, long life, high Capacitance, and low ESR make it ideal for applications such as DC power supply filters, energy storage devices, audio/video signal buffering, and high-frequency signal filtering.
