Ferrite beads and chips, also known as Ferrite beads, is a type of electronic component used to filter out high-frequency noise from another circuit. It is usually connected to the power supply line of an electronic device and electromagnetic radiation generated by the device. The BK20104L680-T is one such ferrite bead – manufactured by Johanson Technology – designed to reduce interference between circuits, such as in automotive applications.

The structure of the BK20104L680-T consists of two nickel-zinc ferrite blocks, two lead wires and a polyester tape. The block is made up of high-frequency lossy dielectric material that is combined with an inductive magnetic core. This structure makes the device ideal for use in noise suppression and power line filtering operations. With its low ohmic resistance and high electrostatic capacitance, the BK20104L680-T also provides greater stability over a wide temperature range, making it suitable for use in high-temperature applications.

The BK20104L680-T is suitable for a variety of application fields, including automotive, industrial, and medical. The device is widely used in automotive applications to reduce certain emissions such as radio frequency interference (RFI) and other types of electromagnetic interference (EMI). It is also used as part of a vehicle\'s electrical system to provide noise immunity and line isolation between the primary harness or wiring harnesses, and the exhaust system. Additionally, this device is used in the effort to improve EMI performance, reduce signal interference, and ensure safe data signals within the system.

The working principle of the BK20104L680-T is based on inductance and high frequency impedance. The two nickel-zinc ferrite blocks act as one large coil, or inductor, and the impedance at high frequencies is very high. This high impedance impedes current flow which lowers the strength of noise signals passing through the circuit. Thus, the device provides a very high degree of noise suppression and noise reduction. The other components of the BK20104L680-T – the polyester tape and the two lead wires – are also important for its effectiveness. The polyester tape, which covers the two blocks, helps prevent corrosion and increases the insulation of the device. The two lead wires provide additional electrical connection between the blocks and the circuit.

The BK20104L680-T Ferrite Bead and Chip is an extremely efficient and effective way to reduce interference between circuits. It provides a wide range of noise suppression and line isolation applications in automotive, industrial, and medical fields. The device features two nickel-zinc ferrite blocks, two lead wires and a polyester tape and operates based on inductance and high frequency impedance.
