Ferrite beads and chips are a type of passive electronic component which serves as an inductor in the form of a cylindrical bead or rectangular chip. These components are designed to provide suppression of electromagnetic interference (EMI) by preventing the extra currents induced from external sources, from reaching the intended target circuit. In the electronics industry, Ferrite beads and chips are used to assist in the shielding of a device’s antenna or circuit from outside interference. They are also used to help reduce the susceptibility of a device to interference.The BK1608HM121-T ferrite bead is an example of a commonly used ferrite chip. It is a high-frequency noise suppressor, with an operating frequency of 1.8 GHz. The chip is made up of three parts: a ceramic core, and two resistor leads. The chip measures 8.0mm in length and 2.1mm in width. It is designed to reduce EMI at high frequencies, suppressing harmonic interference from reaching the device’s sensitive circuits. The chip also helps to reduce radio frequency interference (RFI).The principle of working and the application field of BK1608HM121-T can are based upon the property of ferrite to act as a ‘ferromagnetic choke’. Ferrite material presents a high impedance to alternating currents, whilst at the same time allowing DC current to pass unimpeded. This property of the material creates a high-frequency ‘barrier’ which acts to suppress EMI, which can cause interference with sensitive electronic components.The BK1608HM121-T is typically used for the suppression of signal noise found in power cables and audio equipment. Applications of the chip include cellular phones, Pneumatic pumps, motor controllers, displays and High-speed Eddy Current (HEC) devices. This ferrite chip is also widely used in communication systems such as those based upon IEEE 802.11 standards, and as an external anti-noise shield for data transmission cables. It has been used successfully for suppressing the effects of faulty or unstable sources, and for mitigating the resonant and attenuation effects in transformers and switching supplies.The BK1608HM121-T ferrite chip offers a number of features that set it apart from other ferrite beads. The chip has a high current absorption capability, an inductor which has low impedance at high frequencies, and it also has a high self-resonant frequency, which makes it ideal for suppressing high frequency noise. It also has piezoelectric materials which provide superior EMI shielding performance.In general, the BK1608HM121-T is an efficient way of suppressing high frequency EMI. Its operating frequency of 1.8 GHz shows its effectiveness in providing EMI suppression, and its robust construction makes it a good choice of chip for those who need to suppress harmonic and RFI interference. The ferrite chip can provide the user with good performance, reliability and a cost-effective electrical noise control system.
