Film capacitors, or film dielectric capacitors, are electronic capacitors with a thin plastic film as their dielectric. They typically feature a higher insulation resistance, which makes them suitable for applications where circuit conduction needs to be prevented. Generally, film capacitors are more stable than their other counterparts, such as electrolytic and ceramic capacitors. The specific film capacitor we will be discussing is the 104PPA850KD11.

104PPA850KD11 Application Field

The 104PPA850KD11 capacitors can be used for a variety of applications. These include signal mangling, filtering of power supplies, power electronics, harmonic compensation networks, low-noise switched-mode power supplies, EMI filtering, and motor control applications. This film capacitor also exhibits high stability and small temperature drift, making it ideal for precision equipment. Due to its inherent impedance characteristics, the 104PPA850KD11 is particularly suited for coupling and decoupling applications for low frequencies.

104PPA850KD11 Working Principle

A film capacitor consists of two metal electrodes that form a capacitor’s plates, and a dielectric material that acts as a medium to separate the electrodes. It stores energy in the form of an electrostatic field. When a voltage is applied across the two plates of a capacitor, positive charge accumulates on one plate, while the negative charge accumulates on the other plate. This creates an electric field between the two plates, storing a certain amount of energy. In the 104PPA850KD11 film capacitor, the dielectric material is polypropylene packaged in a form of a thin film.

The 104PPA850KD11 capacitor is able to store a larger amount of electric charge when compared to other types of capacitors due to the special properties of its dielectric, namely, its large electric displacement and permittivity. As the voltage increases, the capacitance increases as well, leading to a capacitive voltage divider type of action. The device also offers excellent peak voltage withstand capabilities, allowing it to become an integral part of many applications involving higher operating voltages.

The 104PPA850KD11 film capacitor also features a low Equivalent Series Resistance (ESR). This means that it offers good self-healing properties, even when operating in extreme environments. Its low ESR also plays a major role in improving the capacitor’s performance when used in filter circuits, as it helps reduce any resistive losses. In terms of its operating temperature, the 104PPA850KD11 capacitor can withstand temperatures of up to +125ºC.
