Ferrite Beads and Chips

BK20104L050-T is a ferrite bead with a rated current of 1.2A. It is suitable for noise suppression in the ISM band, such as WIFI, Bluetooth, ZigBee and other RF signals. This type of bead has a very small size of 0402(1005). In a limited space, it can suppress high frequency noise effectively, increasing the signal to noise ratio.

BK20104L050-T applications mainly include: radio frequency interference filters, EMI protection circuits, common-mode filters, parasitic inductors, inductors for DC/DC converters, on-board antennas for wireless communication, and various other applications. It can be used in power supplies, mobile phones, computers, digital products, consumer electronic products, etc.

Working principle of BK20104L050-T

The working principle of BK20104L050-T is based on the two-layer structure of three port ferrite beads. It consists of a core, a coil, and an insulating layer between them. The core is made of a ferrite material with high permeability, and the coil consists of multi-turn wire coils wound on the core. When there is a high frequency signal through the coil, due to the electromagnetic induction characteristics of the ferrite core, it will produce an induced current which is spontaneously different from the outside world. The noise generated by this induced current is then absorbed by the ferrite material, thus achieving the purpose of suppressing interference. At the same time, due to the high permeability of the ferrite core, it is also effective at suppressing noise from external sources.

Additionally, thanks to the small size of the BK20104L050-T, it can be used in devices that require miniaturization. Moreover, its inductive property also provides additional benefits such as protection against electromagnetic interference, and increased signal integrity. The BK20104L050-T also has a good high-frequency signal impedance matching characteristics and is able to provide excellent EMI protection in a variety of applications.

Conclusion

In conclusion, BK20104L050-T is a ferrite bead with a rated current of 1.2A. It is suitable for noise suppression in the ISM band due to its small size, high permeability of the ferrite core, and its inductive property. Its applications mainly include radio frequency interference filter, EMI protection circuits, common-mode filters, and various other applications. It can be used in power supplies, mobile phones, computers, digital products, consumer electronic products, etc. Additionally, it has a good high-frequency signal impedance matching characteristics and provides excellent EMI protection in a variety of applications.
