Ferrite Beads and Chips

Ferrite beads and chips are essential components for electrical and electronic systems. FBR07UA850SB-00 is one of the most popular ferrite beads and chips and is widely used in a variety of applications. In this article, we will discuss the application field and working principle of FBR07UA850SB-00.

What is FBR07UA850SB-00?

FBR07UA850SB-00 is a ferrite bead and chip used for EMI suppression. The chip has a rectangular bead structure with 4 pins that can be soldered to a PCB, allowing the bead to provide EMI filtering in mobile phones, laptops, and Bluetooth headsets. The chip has a rated impedance of 850 ohms ±30%, and the chip thickness is 1.3mm, with a total size of 7.0 x 12.7 mm. The working temperature range is from -40°C to +85°C.

Application Field

FBR07UA850SB-00 is widely used in a variety of applications due to its excellent EMI suppression capabilities. It is suitable for mobile phones, notebooks, and Bluetooth headset applications due to its small size and low impedance. In addition, the chip is also used in various communication and automotive systems, medical equipment, and consumer products.

Working Principle

The working principle of FBR07UA850SB-00 is similar to that of any other ferrite bead. The chip is made up of two conductors, which form a loop when connected together. When an alternating current passes through the conductors, a magnetic field is generated and the current is effectively attenuated. The strength of the magnetic field is determined by the resistance, inductance, and capacitance of the ferrite bead. This in turn determines the frequency response of the chip, and the overall level of EMI suppression.

Conclusion

FBR07UA850SB-00 is a popular ferrite bead and chip used for EMI suppression. The chip has a small footprint and low impedance, making it suitable for use in mobile phones, laptops, and Bluetooth headsets. In addition, the chip is also used in various communication and automotive systems, medical equipment, and consumer products. The working principle of the chip is similar to that of any other ferrite bead, in which a magnetic field is generated when an alternating current passes through the two conductors.
