Film capacitors are passive components used to store energy and regulate power in circuits. An example of such a device is the MKP385568016JKI2B0, which is a metallized polyester film capacitor with a nominal capacitance of 0.68uF. The capacitor is designed for use in high frequency and high temperature applications, and has a wide range of uses. In this article, we will explore the application field and working principle of the MKP385568016JKI2B0, and review why this particular capacitor is so well-suited for its intended applications.

The MKP385568016JKI2B0 is well suited for use in power supplies, radio frequency (RF) circuits, and audio amplifiers, due to its high leakage resistance, low ESR, high ripple current rating, and low inductance. The capacitor is also ideal for bypass applications, where it is used to shunt transient or switching noise. The capacitor is rated from -55°C to +105°C, and is capable of withstanding voltage surges of up to 250V.

The working principle of the MKP385568016JKI2B0 is based on the same principles as all other film capacitors. A film conductor – typically aluminum or zinc – is placed between two dielectric films to form a capacitor. The dielectric, or insulating, film is made from a polymer such as polyethylene terephthalate (PET) or polypropylene (PP). The capacitor is then sealed in an epoxy potting material to protect it from moisture, dust, and other contaminants.

The dielectric material used in film capacitors offers several advantages over other types of capacitors. The dielectric films are highly resistant to dielectric breakdown, eliminating the risk of electrical arcing. Unlike electrolytic capacitors, the dielectric films do not contain any electrolytes, which reduces the risk of electrolysis and corrosion over time. The properties of the dielectric ensure that the capacitance remains stable throughout its lifetime, and the dielectric material also offers a high resistance to electrical leakage. As a result, film capacitors typically offer superior performance in high frequencies and high temperatures.

The MKP385568016JKI2B0 is a robust and reliable device, and is well suited for a wide range of applications. Its high leakage resistance, low ESR, high ripple current rating, and low inductance make it ideal for power supplies, RF circuits, audio amplifiers, and other high frequency and high temperature applications. Its robust construction and reliable performance make it an ideal choice for bypass applications and other situations where reliable transients or switching noise shunt is needed.
