Ferrite Beads and Chips are widely used in various electronic circuits, including in those used in the automotive, aerospace, and industrial sectors. MI1806J800R-00 is one type of ferrite bead with specialized application field and working principle. This ferrite bead is made of an alloy of cobalt, manganese, aluminum, and oxides of iron. The size of the ferrite bead is 18*06 mm and with the rated current of 800 A.The application field of MI1806J800R-00 mainly can be divided into two categories. The first application of this type of ferrite bead is noise suppression in the radio frequency (RF) area. It is used to absorb the radio frequency and deliver the absorbed energy as heat. By installing this ferrite bead in the RF circuit, it can reduce signal interference and improve circuit performance. The second application of this type of ferrite bead is for high-frequency harmonic filtering, particularly in the industrial and automotive sectors. In these fields, large currents are used and the harmonics generated by them would cause electromagnetic pollution. By fitting the MI1806J800R-00 to the circuit, it eliminates the high frequency harmonic signals, which in turn is beneficial for maintaining a well-regulated current.The working principle of MI1806J800R-00 is very simple. Basically, it acts as a transformer-like inductor when it is connected to an alternating external current. The alternating current generates a corresponding sequence of magnetic fields that is absorbed by the ferrite bead. The process of absorption is determined by the noise frequency, material type, and inductance of the bead. Because of this series of absorption, the alternating current is converted into a static current. Furthermore, each cycle of the alternating current is reflected back in two directions. One of them is to the power source and one of them is to the electronic circuit it is connected to. In this way, it will reduce signal interference and hence reduce potential noise occurrence.Besides its noise suppression application, MI1806J800R-00 also has an anti-surge function. This is thanks to its very high rated current of 800 A. Rated current here acts as an indicator of its ability to withstand high current surges. This makes the MI1806J800R-00 particularly suitable for applications such as high voltage rectification or driving. It can absorb high voltage peaks generated during those operations and protect the circuit it is connected to. At the same time, it can also reduce electrical interference.In conclusion, MI1806J800R-00 is an excellent type of ferrite bead, with very specific application field and working principle. It has two major application field for noise suppression and high-frequency harmonics filtering. At the same time, it also has an anti-surge function, making it ideal for use in areas such as driving and rectification.
