It is frequently used in audio circuits, voltage regulators, and motor starters. Due to its wide range of operating temperatures and high dielectric strength, it is ideal for use in high voltage and high current circuits such as welding machines and AC/DC power supplies. Furthermore, it is also suitable for use in high frequency applications such as radio transmission circuits and electrostatic capacitors.

Apart from electronics and power applications, B25620B0627K701 is also extensively used in automotive industry. It is often used in engine control units, fuel injection systems, shift registers, and traction control systems. Moreover, it is also employed in industrial applications such as solenoids and robotics.

Working Principle of B25620B0627K701

A typical B25620B0627K701 film capacitor consists of a thin plastic film sandwiched between two metal plates or electrodes. The film acts as the dielectric element and facilitates the flow of electrical current between the two electrodes. When an electric charge is applied to the electrodes, the electric field induces a polarization around the film, creating a static charge on the surface of the film. This charge is stored as static electricity on the dielectric material and the dielectric’s charge and voltage capacity increase.

When the electric current is removed, the stored charge can be quickly discharged into the electric field. This effectively prevents the voltage buildup that could otherwise damage the capacitor\'s insulation. In addition, the static charge on the dielectric also prevents the formation of electrical arcs that could otherwise cause short circuits between the two electrodes.

Apart from its ability to store and discharge electrical charges, B25620B0627K701 is also known for its ability to transmit high frequencies. As the frequency increases, its losses become minimal, making it suitable for use in high frequency applications such as radio transmission circuits and electrostatic capacitors.

Conclusion

B25620B0627K701 is a popular and common type of film capacitors used in various industries and applications, and is preferred by engineers and technicians for its wide range of operating temperatures and high dielectric strength. Its working principle involves the induction of electrical charge between two metal electrodes, which is stored as static electricity on the dielectric material. This stored charge can be quickly discharged into the electric field, preventing voltage buildup and the formation of electrical arcs. Furthermore, B25620B0627K701 is known for its low losses at high frequencies, making it ideal for use in radio transmission circuits and electrostatic capacitors.
