Film Capacitors

Film capacitors are components that contain an insulating film as the dielectric. This type of capacitor stores energy by storing electric charge on two facing electrodes (plates). It is mainly used in AC circuits and provides a high degree of stability over time. Film capacitors are usually designed for higher power applications due to their superior dielectric strength and insulation capabilities.

B32928E3456M is a type of film capacitor manufactured by Murata. Its appearance is similar to a disk with two metal terminals. It has a specific application field, which is high-pulse operation, high-frequency circuits, noise-filtering, and to stabilize the power in the AC circuits.

Application Field

The B32928E3456M is most commonly used in high-frequency or high-pulse circuits and power filtering applications. It is suitable for AC circuits, such as AC/DC switching power supplies, adapter products, and AC/DC LED drivers. It can also be used in audio devices, such as amplifiers and audio crossover networks. In addition, it is suitable for applications such as automotive, medical, and industrial electronics.

In particular, B32928E3456M is suitable for 3-phase AC circuits of motor drive systems. It is able to reduce hum, noise and instability associated with the 3-phase AC circuits. It is also suitable for use in high-temperature environments, with a temperature range of -55°C to +105°C.

Working Principle

The B32928E3456M consists of an aluminum foil and a dielectric film. The metal and dielectric layers are laminated together and then covered with a protective coating.

When an AC voltage is applied to the capacitor, it is able to store and release electric charge. It does this by creating an electric field across the film due to the difference in voltage between the metal electrodes. This electric field is what stores the energy in the capacitor.

The capacitor is then able to release energy by controlling the amount of electric charge it stores. This is done by controlling the magnitude of the electric field, which can be adjusted by changing the applied voltage or by changing the size of the capacitor.

The B32928E3456M is able to provide a high degree of stability over time due to its construction. It is highly resistant to changes in temperature and humidity, and it has a high insulation resistance. It also has a higher tolerance to mechanical shock and vibration compared to other types of capacitors.

Conclusion

In conclusion, B32928E3456M is a type of film capacitor that is designed for high-frequency and high-pulse circuits. It is suitable for use in 3-phase AC circuits, audio devices, power filtering and other applications. It can also withstand high temperatures and is highly resistant to changes in temperature and humidity. It is able to provide stability over time due to its construction and is highly tolerant to mechanical shock and vibration.
