Film Capacitors are passive electrical components that can store energy when a charge is applied to two of its terminals. They consist of a dielectric material, which can be a solid or liquid, sandwiched between two conductive plates. It is this dielectric material that enables the capacitor to store energy. B81130C1473M is a type of film capacitor.

Application Field

B81130C1473M capacitors have a wide range of usage in electronics as they are reliable, highly efficient, and cost-effective in comparison to other capacitors. Different electrical and electronic equipment often utilize film capacitors such as the B81130C1473M for their primary energy storage device. Such equipment include computers, displays, power inverters, solar panels, and batteries.

Since film capacitors are less prone to mechanical and thermal degradation, they are widely used in high-end audio applications such as speaker crossovers, audio power amplifiers, and powered speaker systems. B81130C1473M capacitors offer more accurate audio performance thanks to their superior frequency response. They are also widely used in automotive applications, thanks to their high thermal tolerance and low ESR values. In addition, they are also often used in motor starting, frequency converters, frequency drives, and servo-motor applications.

Working Principle

When a charge is applied to B81130C1473M film capacitors, it accumulates electric charge and stores it on two conductive plates. The dielectric then acts as an insulator, preventing electric current from flowing between the two plates. This accumulation of electric charge creates an electric field between the two plates, which is the basis of the capacitor\'s energy storage and current conduction capabilities.

The main electrical characteristic of a film capacitor is its capacitance, which is the ratio of the charge stored on one of the plates to the voltage applied across the terminals of the capacitor. The capacitance of B81130C1473M capacitors is typically in the range of 0.001 - 0.1 µF. The most important property of the dielectric material used in film capacitors is its dielectric constant, as this defines the capacitance of the capacitor. A higher dielectric constant will result in a higher capacitance.

Another important factor influencing the performance of B81130C1473M capacitors is their ESR (Equivalent Series Resistance). ESR is a measure of the resistance of the capacitor\'s internal circuit, which can vary depending on the size and type of dielectric material used inside the capacitor. The effect of ESR is two-fold: it reduces the capacitor\'s efficiency by dissipating energy in the form of heat, and it can affect the performance of circuits when the ESR deviates from the desired value. As a result, it is important to choose the right capacitor for the job at hand.

In conclusion, B81130C1473M capacitors are excellent choices for a wide range of applications due to their stability, accuracy, and reliability. They can be used in both high-end audio and automotive applications, thanks to their high thermal tolerance and low ESR values. With their low cost and high efficiency, film capacitors are the preferred choice for many different applications.
