Film capacitors are often overlooked in the world of electronics, even though they are quite important components when it comes to filtering and signal shaping. B81130C1683M is just one of many film capacitors available in the market. This article will discuss its application fields and working principles in detail.

General Overview of Film Capacitors

Film capacitors, or film dielectric capacitors, are non-polarized capacitors featuring an insulation material applied as a thin layer on two partial planes. These planes are shown as two metal (usually aluminum) conducting plates which are separated by this insulation material (film). They are able to store electric charges, which makes them either perfect for purely storage purposes or for filtering and signal shaping. In comparison with other types of capacitors, film capacitors are very reliable and have an impressive life expectancy.

The form factor is also quite impressive. These capacitors can be further divided into three categories based on shape: axial, radial, and flex. Additionally, the metal plates vary depending on the version you choose, as some are wrapped with metal foil and some with anodized aluminum. If you need a specific shape, such as high voltage, then polyester film capacitors will be your go-to solution.

B81130C1683M Application Fields

The B81130C1683M film capacitor is a non-inductive version that features multiple high-voltage and high-current applications. It is optimized for repetitive polarizing volume discharge up to 2kVrms, and has an impressive capacity range starting from 0.001uF and going up to 1.5uF. This film capacitor comes with dielectric layers made from polyethylene terephthalate (PET) material, which is particularly known for its impressive and lasting insulation properties.

The B81130C1683M is perfect for high-voltage applications due to its big capacitance range and efficient insulation. This is why it is usually used in high-speed POE (Power-over-Ethernet) applications. Additionally, it is also often used in industrial equipment, medical equipment, and other power electronics like UPS (uninterruptible power supplies) or welding machines.

B81130C1683M Working Principle

The B81130C1683M works as all capacitors, following the general underlying working principle. It stores electric energy between two metal plates which are then separated by an insulation material. Electricity is stored between these plates in the form of electrostatic charge. The energy to be stored is determined by the equation C=Q/V , where C is the capacitance, V is the potential, and Q is the charge.

Due to its insulated film layers, once the capacitor is charged, a voltage will be generated between the plates and it will remain until the capacitor is discharged. This makes film capacitors great at storing energy in electric circuits and provides excellent signal noise suppression for AC (alternating current). Additionally, this also makes them ideal for filtering out any unwanted frequency signals.

Conclusion

The B81130C1683M Film Capacitor is one of the most popular options on the market due to its impressive insulation and high-voltage applications capabilities. It is perfect for power-over-ethernet products, and it can also be used in industrial equipment, medical equipment, and power electronics. Additionally, the working principle of this capacitor is similar to any other on the market, as it works by storing electric energy between two metal plates which are then separated by an insulation material.
