Film Capacitors, also known as plastic or dielectric capacitors, are a type of capacitor with a thin plastic or cellulose film layer as its dielectric. One of these capacitors is the BFC238311154. This capacitor is equipped with a polyethylene terephthalate (PET) film as its dielectric for superior temperature-resistant performance. Its features and applications, as well as its working principle, are discussed below.

Features

• High temperature resistant with a wide operating temperature range of -55°C to 85°C
• Flame retardant material
• Small dimensions with a height of 3.5mm and width of 11.4mm
• Total capacity range of 0.0047 to 220uF
• Low ESR performance
• High ripple current and frequency noise tolerance

Applications

This film capacitor is widely applicable and is typically used for the following purposes:

• For coupling and decoupling connections with DC/AC circuits
• For the elimination of interfering signals in circuits
• For smoothing current fluctuations
• for “time Constants” in AC circuits
• For storage of energy in power supplies
• In electronic filters
• In bypass applications
• For charging and discharging

Working Principle

The BFC238311154 is a polarized capacitor, meaning that it must be installed with the correct polarity. This capacitor consists of two electrodes which are separated by the dielectric (PET film). As voltage is applied across the electrodes, a small electric current flows through this capacitor, storing energy in the electric field between the electrodes.

When the current flow stops, the electric charge stored in this capacitor needs to be discharged. This is where the capacitor\'s low ESR performance comes into play. A capacitor with a low ESR can discharge its energy quickly and efficiently. This allows for long life cycles and optimal performance.

The combination of a high-temperature resistant PET film, low ESR performance, and high ripple current makes the BFC238311154 capacitor suitable for a variety of applications. This capacitor is a reliable and robust option for applications where a high-quality capacitance is needed.
