Ferrite Beads and Chips

Ferrite beads and chips act as compact, cost-effective solutions that absorb electromagnetic interference (EMI) in a variety of applications. A ferrite bead or chip is a wire coil or ferrite core with a bead or chip of metallic material attached to the core. When current passes through the ferrite bead or chip, the electrical charge creates a magnetic field that absorbs and dissipates EMI. The result is reduced electromagnetic radiation and low-frequency noise in the affected area, allowing for optimal performance and connection.The 4212R-7 is a ferrite bead and chip from Murata with a 7.5 uH inductance and rated current of 2.7 Amps. This part is designed for mounting on boards with through holes for soldering, but it can also be mounted on surfaces with adhesive. With an operating temperature range of -40 to 85℃, the 4212R-7 is suitable for a variety of temperature environments.The 4212R-7 is primarily used in data and telecom applications, where it works to reduce EMI at the circuit board or system level. It is designed to filter noise coming from the power lines, keyboard lines, and other connector lines. The operating frequency range of this part is up to 1GHz, making it suitable for use in high-speed data transfer applications.The working principle behind the ferrite bead and chip is based on Faraday\'s law of induction. This law states that a current in a conducting wire creates a magnetic field, and a magnetic field moving through a circuit induces an electric field. In the case of the 4212R-7, the current passing through the ferrite core creates a magnetic field which interacts with the electric field of the EMI, resulting in their cancellation. In this way, the 4212R-7 serves as an electromagnetic filter, allowing only desired signals to be transmitted while inhibiting the flow of EMI.The 4212R-7 ferrite bead and chip offers superior performance with a relatively low cost, making it an ideal solution for EMI suppression in the telecommunications and data transfer sectors. In addition, the wide operating temperature range of this product makes it suitable for a variety of applications. With its ability to reduce EMI efficiently and cost-effectively, the 4212R-7 ferrite bead and chip from Murata delivers reliable and consistent performance.
