Film Capacitors

Film capacitors, also known as film dielectric capacitors, are solid state capacitors. They have several layers of dielectric film with electrodes at the top and bottom. These types of capacitors are generally employed in circuits operating at relatively low voltage, such as consumer electronic circuits, audio amplifiers, loudspeaker crossovers, and some kinds of analog equipment. Film capacitors are well suited for AC applications, where they are prized for their stability and low loss.

MKP385410085JC02Z0 Application Field and Working Principle

The MKP385410085JC02Z0 is a type of film capacitor which features a polypropylene dielectric film. This type of capacitor is a general-purpose device suited for use in low-voltage AC applications like audio circuits and power-supply bypass applications. The device is compact and offers very little size and is rated for a capacitance range of 100 pF to 0.12 µF. The maximum operational voltage is up to 630 V AC for this particular capacitor.

The MKP385410085JC02Z0 has a lead spacing of 16.5 mm, and comes in a radial leaded package. This makes the device suitable for surface mount, or through-hole mounting. The MKP385410085JC02Z0 has a working temperature range of -55°C to +85°C. The device is equipped with built in safety features like self-healing properties which makes it an ideal choice for high frequency and low voltage applications.

The working principle of this film capacitor is rooted in capacitance and the dielectric properties of the material. When an electric potential is applied across the capacitor’s terminals, the dielectric material between the electrodes concentrates the field, causing an effective increase of capacitance. The MKP385410085JC02Z0 is composed from polypropylene dielectric film which is known for its low dissipation factor. This means that the device will not suffer from energy losses due to its dielectric material.

This particular model of film capacitor offers many improvements on previous designs, as its internal geometry has been optimized. It has high current handling, so it can be used for applications where a high amount of current is required. It also has low ESR and ESL values. The stabilized voltage leads to a self-adjusting field which improves its overall performance and reduces losses.

In general, the MKP385410085JC02Z0 is suitable for a wide range of applications, such as audio amplifiers, power-supply bypass circuits, and consumer electronics. Its features make it an ideal choice for low-voltage AC circuits, where its stability and low-loss qualities come into play. Its reduced size and shape also make it appropriate for SMD mounting, reducing overall assembly times in the production process.
