Ferrite Beads and Chips

Ferrite Beads and Chips are used to provide filtering or EMI/RFI suppression on signals flowing through electrical systems. They are small passive components that provide a low-resistance path to “ground” for high frequencies that allow low-level or “noise” signals to be effectively filtered.The FBA04VA900NA-00 is a ferrite bead chip that is widely used in electronic applications such as power supplies, automotive or medical electronics, and telecommunications. The FBA04VA900NA-00 provides a superior combination of frequency response, insertion loss, self-resonance, and RF tolerance, making it ideal for a wide range of applications.FBA04VA900NA-00 Application FieldThe FBA04VA900NA-00 ferrite bead chips are primarily used for EMI/RFI suppression in industrial, medical, automotive, communication, and power electronics. They are also used for signal line EMI/RFI filtering, signal line noise reduction, and signal line impedance adjustment. They can also be used in RF transceivers and interface circuits for direct connection of portable refrigerators, computer monitors, and other devices with high EMI/RFI noise levels.Working PrincipleThe FBA04VA900NA-00 ferrite bead chip works by presenting a low-impedance path to the signal frequencies that cause EMI/RFI. This low-impedance path acts like an inductor or a resistor, depending on the signal’s frequency, damping the signal transmission, screening it from EMI/RFI noise, and providing effective filtering.The FBA04VA900NA-00 ferrite bead chip consists of a ferrite core wound with an enameled copper wire, which is encapsulated in a molded, non-conductive epoxy resin body. This construction provides excellent signal attenuation at high frequencies, with a low breakdown voltage and a very low insertion loss, making it ideal for a wide range of applications.In addition, FBA04VA900NA-00 ferrite bead chips feature an internal ground connection that allows them to be connected directly to a ground plane, thus allowing them to filter out signals and noise without the need for an external ground connection. This feature makes them particularly attractive for use in circuits with limited ground connections available.ConclusionFerrite bead chip FBA04VA900NA-00 is designed to effectively suppress EMI/RFI noise in a wide range of applications, such as power supplies, automotive and medical electronics, telecommunications, interface circuits, and RF transceivers. The chip features a ferrite core wound with an enameled copper wire, which is encapsulated in a molded, non-conductive epoxy resin body. It has excellent frequency response, insertion loss and RF tolerance, allowing for effective filtering of high-frequency noise, and an internal ground connection for direct connection to a ground plane.
