Film Capacitors

Film capacitors are passive electronic components, where the dielectric material is a thin film. They possess higher dielectric strength, have higher temperature stability and are better EMI protection to eliminate electrical noise that can interfere with computer and audio equipment. Film capacitors are manufactured with a wide variety of dielectric media, such as polyester, polypropylene, PET, FEP, polyethylene naphthalate and other specialty films.

BF014E0154J is a type of film capacitor which belongs to X2 safety capacitor, it is designed in accordance with the IEC60384-14 standard, it is capable of withstanding overvoltage and high temperatures. It is mainly used in AC 250V/277V 50/60Hz power, suitable for limiting peak voltage for motor-start, AC power circuit and any other applications that need a film safety capacitor.

The working principle of BF014E0154J is that, due to the effect of its dielectric medium (film), when a voltage is applied, an internal electric field is generated within it and collects electric charge on the two plates. These accumulated charges have the effect of “squeezing” the electric field, thereby reducing the voltage between the two plates, therefore it serves to reduce peak voltage and attenuates signal.

Additionally, due to the nature of the dielectric film, it is less sensitive to temperature, and its performance is stable over a wide range of temperature fluctuation. This makes it suitable for a variety of environmental conditions. It also has a long life span and it is able to last twice as long as similar sized electrolytic capacitors.

Film capacitors are smaller and lighter than equivalent aluminum electrolytic capacitors, this makes them a great choice for miniaturized electronic circuits and consumer electronic devices such as LCD TVs, camera lenses, optical lens stabilizers, portable audio systems and washing machines.

The main features of BF014E0154J are:

• High-temperature and overvoltage tolerance: This enables it to withstand temperature of up to 125 ℃ and higher voltages, and provides additional protection.
• Improved performance in low-temperature environments: As the dielectric medium is a film, performance is not affected in extreme temperatures.
• Improved acoustical noise suppression: This makes it suitable for applications such as AC power circuits, motor starters and audio systems.
• Longer operating life: It is able to last twice as long as equivalent electrolytic capacitors.
• Small size and light weight: This makes it suitable for miniaturized circuits.

Overall, the BF014E0154J Film Capacitor is a highly reliable and safe component, making it suitable for a wide range of applications. It is capable of withstanding overvoltage and high temperatures, and is perfect for applications that need a film safety capacitor. It is smaller and lighter than aluminum electrolytic capacitors, and its improved acoustic noise suppression makes it ideal for audio systems and AC power circuits.
