Ferrite beads and chips are the most important components of the electronic circuits. They are used to protect and filter the electrical signals that pass through them.HZ0603B112R-00 is a ferrite bead manufactured by HZM. It provides a broad range of applications in various fields. This article will discuss the application field and working principle of HZ0603B112R-00.

Application Field

HZ0603B112R-00 is designed for use in board-level EMC/EMI noise suppression and dc/ac filtering. Being a SMD type ferrite bead, the package size is only 0603, making it suitable for surface mounting in high-density PCBs. And it has obtained IEC60950/RoHS/UL/ENEC/CSA certification.

HZ0603B112R-00 works most effectively in high-speed signal lines, such as USB3.0, HDMI 1.4, Ethernet, and Serial ATA3.0. It also provides an ideal solution for digital filter applications like EMI/RFI filtering of PC board traces, thus improving overall system performance.

Working Principle

HZ0603B112R-00 utilizes the high-frequency ferrite material and blocked structure of air gap. The high-frequency ferrite material has excellent properties such as high-impedance and high-frequency attenuation, which can effectively reduce interference signals. This ferrite bead is specially designed to provide a high current handling capability of greater than 1A. The air gap in the blocked structure of the ferrite core is filled with a transparent material, which has a great insulation ability

When the current flows through the ferrite core, the comprehensive inductance and temperature coefficient of the ferrite core will reduce the current due to the magnetic field around the core. The core also exhibits a high resistance to the signal, which can weaken and attenuate the electrical signals. When the signal passes through the core, the magnetic field around the core is formed, and the field current is hindered, although the linear current is not affected. On the other hand, it has a strong frequency measurement capability and the attenuation increases exponentially at higher frequencies.

Conclusion

HZ0603B112R-00 is a ferrite bead designed with a compact size for applications with high-density PCBs. The high current handling capability allows it to work effectively in high-speed signal lines and eliminate interference signals. Thanks to the high impedance and high-frequency attenuation of the high-frequency ferrite material, the signal will be weakened and attenuated when it passes through the core. This ferrite bead can be used to provide an ideal solution for EMI/RFI filtering of PC board traces for improved system performance.
