BH074D0394J7D Application Field and Working Principle

Film capacitors, also known as metallized polypropylene capacitors, are passive electronic components used to store energy electrostatically, like a battery. The BH074D0394J7D is a type of film capacitor, well known for its long life, low loss, stability, and small size. It is widely used in a variety of digital electronic products, ranging from home theater systems, television sets, and computers to automotive electronics, medical equipment, and power supplies.

Construction

The BH074D0394J7D is composed of two metalized polypropylene films which have been laminated with a non-toxic, flame retardant plastic housing. The two layers create a stack of several sub-microfarad capacitors. The metalized layers contain an electrically conductive layer of aluminum and an insoluble polypropylene dielectric oxide that has been sprayed onto the layers, allowing the capacitor to store energy. The polypropylene dielectric oxide consists of a few select compound blends; tetrafluoroethylene (TFE), polyhedral oligomeric silsesquioxanes (POSS), and nanocarbons. The non-toxic plastic housing covers the capacitor and all of its components.

Application Field

The BH074D0394J7D is commonly used in a variety of applications. Its low ESR and high dielectric strength make it a reliable option for a wide range of applications. It is suitable for AC and pulse power supply applications, as well as motor and lighting fixtures. Additionally, the capacitor is designed for long-lasting performance and high efficiency in prolonger periods of time. This makes it well suited for applications requiring precision and stability. Some of the devices it is used in include switching power supplies, high-frequency power supplies, and solar energy systems.

Working Principle

The working principle behind BH074D0394J7D is relatively simple. As an electrical current is applied to the capacitor, the stored electric charges interact with the electrical current and create an opposing electric field. This creates a voltage that is applied to the two metalized layers in the capacitor. This voltage is then stored until the external electric field from the current is removed. The electric charge will then retain its stored energy, thereby improving the capacitor\'s performance.

Advantages

The BH074D0394J7D offers various advantages including high stability, low noise, excellent capacitance and long life. Its stored energy is very reliable and can be used in high frequency power supply circuits, making it ideal for applications requiring accurate timing pulses, such as those associated with LED lighting systems. Additionally, the capacitor is rated to have a higher voltage rating than other standard capacitors, allowing it to be used in higher voltage applications. Furthermore, the capacitor is designed with an insulation system to prevent damage to the capacitor due to high temperature and to provide increased durability.

Conclusion

The BH074D0394J7D is a film capacitor designed for long life, low loss, stability, and small size. It is suitable for a variety of applications and offers a high level of performance with excellent capacitance and low noise. The capacitor is designed with a high voltage rating and an insulation system to increase its durability. In addition, the capacitor offers a reliable and stable stored energy output for improved performance in applications such as switching power supplies, high-frequency power supplies, and solar energy systems.
