Ferrite Beads and Chips

Ferrite beads and chips are designed to mitigate susceptibility to electromagnetic interference (EMI). The FBA04HA900BB-00 is a chip-type ferrite bead that is a type of electronic component used to suppress high-frequency noise in electronic circuits. It is the most commonly used device for suppressing high-frequency noise because it can be inserted directly into circuit boards without the need of wires or soldering.

Application Field of FBA04HA900BB-00

FBA04HA900BB-00 is generally used in signal line filtering applications such as USB, DVI, HDMI, 1394, and audio. It finds application in many consumer and automotive electronic products including cell phones, portable media players, HDTVs, digital cameras, car infotainment systems, etc. The FBA04HA900BB-00 is also used in many industrial products such as medical equipment, communication equipment, radar systems, etc.In addition to identifying signal line noise suppression, FBA04HA900BB-00 can also help reduce the size and cost of printed circuit board (PCB). The small size of the chip enables designers to easily fit it into restricted spaces due to its small size. Also, it is one of the most cost-effective forms of noise reduction for the PCB.

Working Principle of FBA04HA900BB-00

The external shape of an FBA04HA900BB-00 ferrite is a flat chip having an approximately rectangular shape. Along its two sides are thin metalized coatings. The chip itself is composed of iron oxide and ceramic materials having high electrical resistance.The working principle of FBA04HA900BB-00 is based on its property of having high inductance. It consists of a ferrite core surrounded by a wire windings and two terminal contacts. It functions as an inductor and the voltage drop is proportional to the frequency. As a result, at high frequencies, the voltage drop across the chip lowers the circuit’s noise.When electricity passes through the FBA04HA900BB-00, it creates a magnetic field and induces the current to flow in a closed loop around the ferrite beads. As the electrons move around the bead, they cause the bead to vibrate, creating a magnetic drag or a resistance to the current. This process causes a reduction in the amount of noise being generated.

Conclusion

FBA04HA900BB-00 is a chip-type ferrite bead used in signal line filtering applications to suppress high-frequency noise in electronic circuits. It is widely used in many consumer, automotive and industrial products to reduce the size and cost of printed circuit boards. It achieves noise reduction through its inductor properties and its ability to create a magnetic drag when electricity passes through the chip.
