Ferrite Beads and Chips - BK1005HR601-T Application Field and Working Principle

Ferrite beads and chips are usually the devices of choice when it comes to suppressing unwanted electronic noise. The BK1005HR601-T, in particular, is one of these devices, often used in communication systems to reduce power supply noise. This article looks into the field of applications and working principle of the BK1005HR601-T.

Applications

The BK1005HR601-T is a ferrite bead-type EMI suppression device, mostly used in communication systems to reduce power supply noise. It is especially effective in applications where high-frequency switching currents flow, such as bus and digital menu systems. The BK1005HR601-T has a high impedance level, high efficiency, low-profile design, and is highly reliable. It is recommended for use in devices operating at frequencies from 10MHz to 500MHz.The BK1005HR601-T is also a good solution for any application requiring impedance control on power line, such as a specific type of power supply. It can reduce power supply noise, reduce the harmonic resonance of the power supply, and provide protection against static electricity.

Working Principle

The BK1005HR601-T works on the principle of electromagnetic impedance conversion. It consists of a copper-coated ferrite bead wrapped around a tiny core and connected to a pair of insulated wires. This bead is designed to absorb and convert high-frequency AC signals, essentially acting like a low-pass filter.When the BK1005HR601-T is connected with a power supply, it will absorb high-frequency signals and reduce interference before it reaches the device, effectively suppressing unwanted noise while still allowing the desired signals to pass. The bead is also designed to convert the high-frequency AC signals into tolerable voltage values.The BK1005HR601-T also comes with an additional wire loop that can be used to provide added protection against static electricity. It works by grounding the circuit when a physical shock is applied, reducing the risk of any harm to the device.

Conclusion

The BK1005HR601-T is an EMI suppression device that is often recommended for use in communication systems and power supply applications, due to its high efficiency and low-profile design. It can reduce the interference levels of high-frequency AC signals by converting them into more tolerable voltage values. The BK1005HR601-T also features an additional wire loop for additional protection against static electricity.
