In the protection of electronic circuit, the EMI-1206-120 ferrite bead and chip has played a critical role. This kind of product is widely used in the industry for its excellent characteristics. It can effectively reduce the interference between the circuit and eliminate the high frequency signals, so as to protect circuit from any damage.

The EMI-1206-120 ferrite bead and chip is a kind of chip-resistant, high-frequency, high-stiffness, low-power consumption components with electromagnetic shielding capability. The chip is composed of nanocrystalline iron particles, the protection rating equivalent to near zero when the chip is operated. Its operating frequency is typically up to 500MHz and the insertion loss is up to 40dB.

The advantages of the EMI-1206-120 ferrite bead and chip are as follows:

• Good high frequency characteristics;
• High sensitivity to current changes and low power consumption;
• High interference suppression capability, good shielding and low insertion loss;
• Easy to install, no need for additional mechanical support.

The working principle of the EMI-1206-120 ferrite bead and chip is that it absorbs the high-frequency disturbance signals and converts them into low frequency signals, thus protecting the PCB board from interference. The chip is connected with the conductor through a special flux-inducing layer. When the circuit is energized, a current will be induced in the flux-inducing layer to create a magnetic field. The magnetic field generated will interact with the high frequency signals travelling through the circuit and extract the power of the signals, reducing the interference. The absorbed power will be converted into heat, which is harmless.

In telecommunications, computers, instrumentation, home appliances, industrial control and other areas, EMI-1206-120 ferrite bead and chips have been increasingly used. As an effective protection component, it has many advantages, such as high sensitivity to current changes, high electromagnetic shielding capability, low power consumption, ease of installation, etc., and thus has been widely used in the industry.
