Ferrite Beads and Chips: MH4516-102Y Application Field and Working Principle

Ferrite beads and chips are composed of different combinations of metal, ceramic or some other inert materials. Based on its difference in materials, ferrite beads and chips can be divided into different types, such as axial ferrites, SMD ferrites, chip ferrites, and impedance beads. Each type has different applications.

MH4516-102Y Application Field

MH4516-102Y ferrite chip beads are part of the EMF4516 series and feature a maximum DC resistance of 1 ohm. These chip beads are composed of three parts: an outer conductive coating, a ferrite core and a ferrite connectivity center. These chip beads are known for their consistent performance and widely used in various industrial, automotive and electronics applications. For example, they are commonly used in automotive electronics, ignitions, general purpose switching and power supplies, RF applications, ceramic capacitors, and other peripherals.

MH4516-102Y Working Principle

MH4516-102Y ferrite chip beads are inductive components that work by blocking high frequency (HF) electromagnetic interference (EMI) signals from traveling along power and signal cables. The ferrite core dissipates the interference energy in the form of heat. The outer conductive coating prevents the interference from travelling any further by providing a shielding around the core and conducting any unwanted energy away. The ferrite connectivity center provides a connection between the chip bead and the cable.

The chip bead\'s inductive properties depend upon the core material and size, as well as the number of turns in the windings. A single layer of chip bead will typically offer low impedance to direct currents, low impedance to low frequency alternating current (AC), and high impedance to high frequency AC. This high impedance allows the chip bead to effectively block EMI interference.

Conclusion

MH4516-102Y ferrite chip beads offer consistent performance in various industrial, automotive and electronics applications. Their inductive properties make them effective in blocking unwanted EMI interference from travelling along power and signal cables. The chip bead is composed of three parts, an outer conductive coating, a ferrite core and a ferrite connectivity center. Each of these parts has a role in blocking the interference and dissipating its energy in the form of heat.
