Film capacitors, otherwise known as metallized film capacitors, or Polyethylene Naphthalate Film capacitors (PEN capacitors), are high temperature, high voltage, general purpose, aluminum electrolytic capacitors manufactured with wound and metallized polyethylene naphthalate (PEN) film as the dielectric material. They are manufactured in different shape, sizes and voltages and the BFC238341124 is one type of these capacitors.

The BFC238341124 is basically an aluminum electrolytic capacitor with a wound film dielectric, which is primarily used for a variety of applications. It is composed of a metalized polyethylene naphthalate (PEN) film dielectric, which offers superior performance at elevated temperatures and humid environments. This type of capacitor offers stable capacitance tolerance, high frequency process capability, low ESR values, and high ripple currents at increased temperature.

The BFC238341124 is typically used in power supplies, high frequency converters, digital audio, AC/DC electronic ballasts, used in consumer electronics, medical equipment, industrial motor controls, consumer appliances, microwave and communication systems. The capacitor can be used for TV flybacks, computer peripheral charging, hard disk drives, server power supplies, and telecom systems etc.

The working principle of the BFC238341124 is quite simple yet effective. The capacitor consists of two metallic plates and a dielectric material between them. An electric field is set up when voltage is applied across the plates. The electric field is created by the proportional difference between the charge inside and outside the capacitor. This electric field produces an electrostatic field, which acts to store energy and cease the flow of current in AC circuits.

The dielectric material between the capacitor plates has certain electric-fields dependant properties. The values of these properties control the Capacitance, Dielectric dissipation factor (Df) and Dielectric constant. As a result, the BFC238341124 is designed to have a lower dissipation factor, or ESR, and a higher capacitance when compared to the traditional metalized film capacitors.

The capacitor also reduces the micro-ripple current during operation, and has a higher temperature coefficient of capacitance due to its higher dielectric constant. The lower ESR and higher capacitance offer an overall improvement in the performance of the capacitor, which makes it suitable for most applications.

In conclusion, the BFC238341124 is a high temperature, high voltage, aluminium electrolytic capacitor. It is composed of a wound film dielectric, which is primarily used for a wide range of applications because of its low ESR and high capacitance. The capacitor reduces micro-ripple current, improves the temperature performance and is suitable for most modern day applications.
