Ferrite beads and chips are ferromagnetic materials, commonly called magnetic beads. Ferrite beads are components made of ferrite and can be molded into various shapes. The current passing through the ferrite beads will produce hysteresis loss and this loss will dissipate as heat.
HF70ACB201209-T is one of the ferrite beads and chips in this category. It is mainly used for signal filtering in electronic circuits. Typical application fields are automobile electronics, digital broadcast systems, electronic household appliances, liquid crystal displays, LCD televisions, mobile handsets, and other fields.
The structure of HF70ACB201209-T is composed of a ferrite core and two terminals. It has low loss, high insertion loss, and high DC resistance. When the high or low frequency reaches the operating frequency range, the device will filter and absorb part of the high or low frequency signals, eliminating the interference. The strong anti-interference ability of HF70ACB201209-T can effectively filter out unnecessary noise signals in the electric circuit and improve the signal transmission effect.
The working principle of HF70ACB201209-T is that after the signal is applied, the current flows into the ferrite core. This current is subjected to hysteresis loss of the ferrite core, generating heat and dissipating the unnecessary signal. At the same time, because the magnetic field generated by the current can produce a leakage magnetic flux, the DC resistance of the ferrite core can be increased. Thus, the larger high-frequency and low-frequency signals will be filtered out, while the lower frequency signals will remain in the electric signal.
HF70ACB201209-T can be broadly applied in high-end communication electronic products, electronic instruments, automotive electronics and other high-frequency applications, providing excellent EMI performance. It is an ideal component for signal filtering in electronic circuit designs.
