Film capacitors are passive electronic components used in a wide range of applications, including AC and DC decoupling, supply filtering, bypassing, resonance and even energy storage. The 947D181K122BCMSN is a film capacitor that has many different applications and working principles. The following will explain what these are.

DC Blocking

A film capacitor can be used as a DC blocking capacitor in order to prevent current from flowing in a circuit. Due to the dielectric strength of the film, it can block low-frequency DC voltages without having to resort to the use of inductors, making them ideal for applications such as audio. For this application, 947D181K122BCMSN provides 2 kv DC blocking voltage for protection from over voltage.

AC Coupling

The 947D181K122BCMSN offers excellent AC coupling, meaning it can be used to reduce or eliminate AC interference and noise for applications in such fields as audio and signal processing. The capacitance value is designed to determine the amount of AC signals that can pass through the capacitor, therefore allowing for a perfect balance between reducing noise and signal losses. This component is also ideal for AC power line filtering and frequency dependent impedance matching.

Supply Filtering

A film capacitor\'s ability to reduce ripple currents and filter out high-frequency noise makes it the go-to choice for supply filtering applications. The 947D181K122BCMSN can reduce AC voltage by acting as a high-frequency noise filter for AC power supplies. This noise can be caused by high-frequency components or other sources, and the capacitance value of the component is designed to determine the frequency of the interference that is filtered out.

Bypassing

Film capacitors are also used for bypassing applications, such as in power supplies. To do this, the component is placed between the positive input of the power supply and the ground. The capacitor reduces the amount of noise and ripple current by providing a low-impedance path to ground. This is especially important when the input voltage is noisy or has large ripple currents, allowing the power supply’s voltage regulation stage to work more efficiently.

Resonance

The 947D181K122BCMSN can be used in conjunction with an inductor to form an LC resonant circuit. This type of circuit is useful for applications in which a certain frequency needs to be tuned. By adjusting the capacitance,interference, inductance or both, the LC component can be adjusted to match the frequency of the signal that needs to be tuned.

Energy Storage

Film capacitors are ideal for energy storage applications, because they can hold a significant amount of charge in an extremely small space. This makes them perfect for use in devices such as mobile phones, which rely on a small amount of energy being stored in order to keep them running. The 947D181K122BCMSN has a capacitance value of 1,22 uf, making it suitable for energy storage applications.

In conclusion, the 947D181K122BCMSN is a film capacitor that has many different applications and working principles. It can be used for blocking DC voltages, AC coupling, supply filtering, bypassing, resonance and even energy storage. By understanding the working principle and applications, engineers can design more efficient and accurate circuits.
