Film capacitors, also known as plastic film capacitors or polyester film capacitors, are a diverse family of capacitors which use an insulating plastic film as the dielectric. The MKP385491016JI02W0 is a type of film capacitor that has a variety of applications and works on a basic principle described here.

The MKP385491016JI02W0 capacitor typically has a voltage rating of 400 VAC, features metalized polypropylene dielectric material, and has a capacitance of 0.001 µF or 1 nF. It is available in two forms, an axial lead version and a surface-mount variant. The axial lead version is preferred in most applications since it offers improved electrical performance. The surface mount version is smaller and therefore easier to install.

While the exact construction of a film capacitor varies across manufacturers and models, the MKP385491016JI02W0 uses an intricate process to form the capacitor’s dielectric. It places a thin plastic film between two metalized surfaces, forming a dielectric layer with a comparatively higher dielectric constant. The capacitor is then sealed with epoxy or a metal to protect it from moisture, dust, and other environmental factors that could damage the device.

The working principle of a film capacitor is based on the fact that there is a deficiency in the outer surface of the dielectric material in comparison to the inner surface. This deficiency or imbalance allows electrons to move from the inner to the outer surface, creating an electric field between the metalized surfaces. As electrons move from one surface to the other, they create a storage of electrical energy. By adjusting the distance between the two surfaces, the voltage rating of the capacitor can be changed.

One of the main advantages of the MKP385491016JI02W0 is its wide operating temperature range, which is between -55°C to +125°C. This makes it suitable for a variety of applications, such as electric motor starters, panel meters, digital set-top boxes, measuring instruments, and small motor controls. It is also suitable for use in low-profile devices such as wristwatches and hearing aids, as well as in circuit boards, switching systems, and power supplies.

In addition to its wide operating temperature range, the MKP385491016JI02W0 offers higher dielectric strength and excellent stability over time when compared to other film capacitors. It is also highly reliable with low losses and excellent load endurance. Lastly, it is one of the most affordable capacitor options available.

Due to its performance, size, and price, the MKP385491016JI02W0 is a popular choice for various applications. It is a great choice for those who need a film capacitor with a wide operating temperature range and superior performance. With its impressive features, the MKP385491016JI02W0 film capacitor is sure to be a great addition to any application.
