Film Capacitors

Film capacitors, which consist of a metallized plastic dielectric, are high-precision, low-inductance, and high-reliability capacitors. The two main types are Polypropylene (PP) and Polyester (PET) film capacitors. Generally, film capacitors are more reliable and more stable for most applications than ceramic capacitors, due to their low inductance, low ESR (Equivalent Series Resistance), and they can eliminate microphonic noise in sensitive circuits.

MKP385336085JFI2B0 application field and working principle

The MKP385336085JFI2B0 is a 300V AC/DC rated metallized polypropylene (PP) safety capacitor with EIA installed and radial leads. It is specially designed for use in UL listed, box-type touch plates and door bell circuits. The application fields includes light and sound, WARNING PLATE, POR, motion control, professional audio & video, remote control, data & telecom, medical appliance, information security, etc..

The working principle of the MKP385336085JFI2B0 film capacitor is that when the AC voltage is applied across the metalized film, the alternating electric field causes the fields in the dielectric material between the plates to change so that the dielectric material absorbs electric energy. Capacitance is defined by, relative dielectric constant (Kd), plates area (A) and distance between the plates (d). The capacitor can transfer electrical energy at high speed and large charge/discharge current is also possible.

The MKP385336085JFI2B0 film capacitor operates in the frequency range of 16Hz ~ 30kHz with a capacitance value of 0.085µF and a rated voltage of 300V AC/DC. The metallized dielectric (called "film") is made of polypropylene (PP) and the construction is self-healing. This leads to lowEquivalent Series Resistance (ESR) and loses only the smallest amount of energy when in use. It is typically used in light and sound circuits, WARNING PLATE, POR, motion control, professional audio & video, remote control, data & telecom, medical appliance, etc.
