Ferrite Beads and Chips are widely used in applications involving frequency control, signal and power filtering, and noise suppression. A Ferrite Bead is a component made up of a doughnut shaped piece of ferrite material with the purpose to suppress high frequency noise that can modify a current in a circuit. Ferrite Chips are the same component but are made up of a smaller ferrite material and are often employed in filters, rectifiers, switching devices, speakers, and other devices with high current carrying capabilities.The EMI1206R-1200 is a Ferrite Bead specifically designed for use in high-frequency circuits, such as EMI filters, RF filters, wire-bonded filters, and hybrids. It is a small, enclosed component that has an effective diameter of 12 mm. The 1200 denotes a resistance value of 1200 ohms when tested at a frequency of 100 MHz.The EMI1206R-1200 works by trapping and dissipating high frequencies from signals such as RF and EMI signals. The frequency is trapped and dissipated through the body of the chip; creating an electromagnetic charge between the electrons in the chip and the electrons of the passing signal. This prevents the passing signal from being altered by the high frequency noise.When looking at the working principle of the EMI1206R-1200, it is important to understand that Ferrite Beads and Chips only operate in the frequency range of 50 to 100 MHz; any frequencies outside of this range will not be blocked by the Ferrite Beads and Chips. The effectiveness of EMI1206R-1200 is also limited by the amount of heat produced by the current passing through it. As the current increases, the heat generated by the current will reduce the effectiveness of the Ferrite Beads and Chips.EMI1206R-1200 is an ideal component to use for the following applications:• EMI/RF filter• Rectifier• Switching Devices• Wire Bonded Filters• Speaker Filter• Noise Suppression• High Frequency CircuitDue to its small size, the EMI1206R-1200 can also be used in applications with limited space, such as on a motherboard or in a hand-held device.Overall, the EMI1206R-1200 is an efficient and reliable Ferrite Bead and Chip that is designed specifically for high frequency circuits. It is able to effectively trap and dissipate high frequency signals while allowing for a consistent current flow. While the application fields and working principle of the EMI1206R-1200 are mostly suitable for high frequency components, its small size makes it an ideal fit for applications that have limited space.
