Ferrite Beads and Chips are electronic devices used to suppress high-frequency signals and protect circuits from post-switch electrical events and are commonly used as EMI/RFI suppressors. One example of these devices is the BK1608HM121-TV, which is an EMI suppression bead suitable for telecommunication systems, such as television and radio equipment. This article will discuss the application field and working principle of this product.The BK1608HM121-TV provides reliable protection against electromagnetic interference (EMI) and are suitable for a variety of communication applications, including television and radio equipment. It is designed to suppress high-frequency signals in the range of 0.2MHz to 4MHz, making it suitable for use in a wide variety of applications. As a result, it is often used in applications such as telecommunications, automotive, medical, aerospace, and military applications. The BK1608HM121-TV consists of a ferrite core with two terminals connected directly to it, which allows the bead to be fitted into the circuit in series or parallel by soldering. The high frequency energy is then diverted to the ground through the core, thus suppressing EMI by providing a low-impedance path to ground. This is done by creating an inductor–capacitor (LC) filter, which is designed to reduce electrical noise and interference. The bead provides an impedance that is dependent on the frequency applied to it, as the higher the frequency of the signal, the higher the impedance of the bead. This means that the BK1608HM121-TV is more effective against higher frequencies, and its overall effectiveness is determined by its inductance and capacitance values, which are specified in the datasheet. The device is typically used as a filter for reducing the amount of interference caused by EMI signals, and it can also be used for noise and spike suppression in electrical circuits. It is also suitable for use in high-voltage and fast-transient applications. The BK1608HM121-TV is also rugged and highly durable, and is designed to keep the circuit impedance low over a wide range of frequencies, making it an ideal choice for many applications. In conclusion, the BK1608HM121-TV is a reliable and cost-effective solution for noise and EMI suppression in telecommunication systems such as television and radio equipment. It features a ferrite core with two terminals connected directly to it, and provides an effective impedance that is dependent on the frequency of the signal applied to it. This makes it suitable for a variety of communication applications, as it is highly efficient and rugged.
