Film Capacitors

Film capacitors are a type of electrical components which are used to store electrical energy and thus have the capability of suppressing surge voltages, smoothing incoming power, increasing efficiency, and providing voltage regulation. Manufactured in various forms, film capacitors use layers of thin plastic-based films, making them inherently safe and highly reliable. With its unique features and advantages, film capacitors are being used broadly for both general-purpose and specific applications in circuits, particularly for electronic devices dealing with both high and low voltage applications.

B32362A4107J080 Application Field and Working Principle

The B32362A4107J080 film capacitor, made by EPCOS, is in particular designed for braking, filtering and decoupling applications in telecommunications, home and office electronics, and industrial control. This particular film capacitor contains two metallized polypropylene films which are connected with the help of a wound construction and then evaluated within an impregnating medium of thermosetting epoxy as well as an external epoxy resin label. The capacitor is designed in such a way that its metallized films are brought close together without any interruptions, providing superior performance in comparison to other film capacitors.

The B32362A4107J080 film capacitor has a dielectric strength of 10,000V AC and the failure rate is 0.1% at 85°C in the rated voltage of 630V AC. This helps reduce failure rate in the product life cycle. Moreover, it has a high dielectric loss of less than 0.3%, a wide operating temperature range of -55°C to +90°C, along with a very low dissipation factor of 0.2% at 1 kHz for its frequency range of 0.5 Hz to 1 MHz.

The frequency range of the B32362A4107J080 typical working principle is 0.5 Hz to 1 MHz, meaning that it is capable of working with different frequency signals. The working principle of this film capacitor is based on capacitance and inductance. It basically consists of two conductors separated by a dielectric material which can store electrical energy by creating an electromagnetic field as electrical charge is passed through it. As soon as the electrical charge reaches the capacitor, a current is created and stored on the plates of the capacitor. This stored current is then maintained until the supply current is stopped or the capacitor is discharged. This film capacitor works in the same manner for high voltage applications, with the only difference being the presence of a dielectric strength higher than the rated voltage.

Additionally, B32362A4107J080 film capacitor also offers excellent high current stability, high dielectric strength, and excellent steady-state characteristics which makes it suitable for a wide range of applications such as inverters, soft-start controllers, power supplies, and robot/vehicle controllers. This capacitor is also capable of handling high temperature, making it suitable for use in various areas of electronic components such as industrial automation, power supplies, high power inverters, motor drives, and automotive electronics.

In conclusion, B32362A4107J080 is a high performance film capacitor which is designed with excellent frequency characteristics, high current stability, and high dielectric strength. It has a wide range of applications in various fields such as telecommunications, home and office electronics, industrial control, and even automotive electronics. With its superior characteristics, it is definitely a great choice for many types of circuits and applications.
