Ferrite Beads and Chips

The EMI1206R-90 is a ferrite bead chip which is designed to filter out high frequency electromagnetic interference (EMI) in electronic devices. It works by passing high-frequency alternating current (AC) signals through a conductive material with a high magnetic permeability material. The bead "captures" the interfering frequencies and turns them into heat, which dissipates away.

Application

This ferrite chip is used in all types of electronic circuit boards in order to reduce the amount of EMI which could interfere with other components or circuits. The EMI1206R-90 is most commonly found in commercial electronic products such as computers, audio equipment, mobile phones, and some medical devices. It is typically used in high-performance analog and digital applications such as multimedia systems, networking applications, motor controllers, and power converters.

It is also used in automotive applications such as computer system controllers, powertrain controllers, engine control modules, and body controllers. Additionally, it is used in home appliances such as washing machines, refrigerators, and microwaves, as well as consumer electronics and gaming consoles.

Working Principle

The EMI1206R-90 chip works by passing alternating current signals through a conductive material with a high magnetic permeability material. This material produces a magnetic field that reflects the high-frequency AC signals, effectively absorbing them and preventing them from interfering with other components or circuits.

This ferrite bead chip filters out high frequency EMI signals by turning them into heat. This heat dissipates away through the chip, which prevents the interference from affecting other components. Additionally, the chip has a low-resistance path, which prevents it from disrupting the flow of current in a circuit.

The EMI1206R-90 is an effective way to reduce the amount of EMI interference in all types of electronic circuit boards. It is a necessity for any high-performance analog or digital applications as well as automotive and home appliance applications.
