Ferrite Beads and Chips are one of the most useful components in the electronics industry. The FBMH4516HM851NT is a chip used in this type of electronics. It is quite small and has a package size of 2.2mm x 0.6mm, making it one of the most convenient components for many applications. By understanding its application field and working principle, one can see why it is so important.

Application Field

The FBMH4516HM851NT is primarily used in RF devices as a filter, attenuator and suppression device. This component helps to reduce the interference of RF signals that can be harmful, and is used in many applications such as automotive, audio and video, mobile phones, telecom, medical, RFID and aviation. It is particularly useful in applications that require high impedance, such as mobile phones, as it can help to reduce the impedance caused by different signal frequencies. As well as this, the FBMH4516HM851NT can be used as a current limiter, which is very useful in sensitive electronics with low voltage and low current. In these applications, the FBMH4516HM851NT limits any surge of current that can be caused by fluctuations and signal bounce.

Working Principle

The FBMH4516HM851NT consists of two ferrite cores, each of which contain a coil of wire. These cores are connected in series and the coil of wire wrapped around them creates an RF inductor. The two cores act as capacitors and this helps to reduce the impedance caused by the high frequency signals. When current flows through the device, the ferrite cores interact with the current and create a resistance, which absorbs any EMI signals that pass through the device. This helps to reduce the interference caused by EMI and also helps to keep the signals within the requirements of the application. The core and wire combination also helps to increase the power dissipation, which is essential for RF applications.

The FBMH4516HM851NT is an extremely useful component as it can help to reduce interference caused by EMI and also limit surges in current. It is often used in mobile and RF applications and can help to keep different signals within the specified requirements. By understanding its application field and working principle, one can see why it is such an important element in the electronics industry.
