Ferrite beads and chips such as BLMs have numerous applications and possess unique benefits in the engineering world. The BLMs’ are composed of a core around which a conductive wire is wrapped. The core part consists primarily of iron oxide. These devices are often referred to as inductors, beads, chokes, or filters. The BLM18KG601BH1D has two configurations within which it operates: differential mode and common mode. The most common application of BLM ferrite components is in high frequency noise suppression for analog and digital signals.

Common Mode Mode Operations

During common mode operations, equal and opposite currents flow through the BLM. The effects that this coaxially wound structure has is that it can drastically reduce common mode noise due to its impedance being at its peak when the two currents have the same magnitude and direction. In this mode, BLMs are commonly used in radio frequency interference reduction in digital and analog control circuits.

Differential Mode Operation

Differential mode operations involve the current creating a current loop within the BLM. It is during this mode that the choke exhibits power line interference and noise suppression. In this mode, BLMs are commonly used for power supply interference reduction and control in digital and analog circuits. More specifically, they are used for common mode noise reduction in control systems.

Conclusion

BLM18KG601BH1D is a great example of ferrite beads and chips, that has numerous applications in the engineering world. Its most common applications are in noise suppression and interference reduction in digital and analog control systems. Its two configurations, common mode and differential mode, allow for it to be used for noise reduction in each of these specific applications. It is used in high frequency noise suppression for both analog and digital signals, power line interference reduction in control systems, and also common mode noise reduction in control systems.
