Film capacitors are one of the commonly used capacitors in the electronics industry. They are unique in that they have a very thin dielectric film as their element which enables them to exhibit outstanding electrical characteristics. The BQ074D0684J is one of the kinds of film capacitors, designed for a variety of applications.

The BQ074D0684J film capacitor features a self-healing film and is suitable for applications such as filters, resonators, decoupling, bypass, compensating and AC motor run capacitors. It is a plastic-housed, impregnated type designed for AC line applications. It has a maximum operating temperature of 85° and a large capacitance range from 0.047µF to 4.7µF to ensure suitable solutions for a wide range of applications.

Since BQ074D0684J film capacitors operate at both 100Hz and 400Hz frequencies, they are ideal for AC power supply decoupling in inverters, electronic ballasts, HID lighting systems, and power supplies. Also, they are favored for use in telecommunications and entertainment systems as well as automotive and industrial power supplies.

The design of BQ074D0684J film capacitor is based on the principle of electrostatic capacitance which states that two parallel conducting plates separated by an insulating material (or dielectric) will store electrical energy. In this particular design, the electrodes are made from the plastic dielectric and the dielectric material itself, creating a very stable electrical behaviour. Due to the thinness of the dielectric material, the capacitance of the BQ074D0684J film capacitors is much higher than that of other capacitors.

Unlike electrolytic capacitors, the BQ074D0684J film capacitor has a low ESR (Equivalent Series Resistance), zero voltage drop, fast response time, and no effect of temperature change on its performance. Furthermore, it has a high ripple current rating which gives it additional durability and a high-temperature rating.

In addition, the BQ074D0684J film capacitors also have low inductance, ensuring high speed of the data transmission and wide range of frequency band. They also feature an excellent noise-reducing ability and a high dielectric strength which is necessary for insulation in harsh environments, making them suitable for use in automotive and industrial applications.

The BQ074D0684J film capacitor is highly reliable and efficient and provides great performance in a variety of applications. Its excellent performance characteristics, small size, and long-term reliability make it an ideal choice for a wide range of applications.
