Ferrite Beads and ChipsFerrite beads and chips are components that block high frequencies from entering circuit boards and equipment. These components are composed of ferrite, an iron-oxide material, and are usually available in two general types: Surface Mount and Through-Hole. The BLM18EG221SZ1D is a through-hole ferrite chip.The BLM18EG221SZ1D has various properties and applications. It is a 3mm X 3.5mm X 1.2mm size Ferrite Chip. It has a high inductance of 22 μH and low insertion loss of up to -10 dB. It has a high-frequency range of 100MHz - 500MHz and operating temperature range of -40°C to +85°C. It is also RoHS-compliant and Halogen-free. The BLM18EG221SZ1D is designed primarily for high-frequency noise suppression in power supplies, communication, and signal line circuits. It smoothly filters out noise and harmonics that can interfere with the current signal, helping to improve the integrity of the signal. This ferrite chip is also excellent for eliminating the generation of EMI and RFI (Electromagnetic Interference and Radio Frequency Interference).In power supplies, the BLM18EG221SZ1D will help to reduce electrical noise on the input DC power line. This will help prevent cross-talk between circuits and reduce the amount of digital noise generated from the AC to DC power converter. This component is also an excellent choice for power line filtering or ground line filtering. It is particularly useful for suppressing common-mode noise in a two-wire switched-mode power supply (SMPS) system.In communication and signal line applications, the BLM18EG221SZ1D will help reduce the relationship between signals and also provide DC power line balance. This component will help to reduce noise levels in an audio power amplifier or signal transmission lines. It is useful in the suppression of EMI in many communication systems.The working principle of the BLM18EG221SZ1D is based on the Faraday cage effect. The ferrite material acts like a mesh wire cage that absorbs and shields electromagnetic interference (EMI), radio frequency interference (RFI), and other noises. It creates a low-impedance path to ground and an associated high impedance path to the source of interference. This shields the circuitry from outside interference, resulting in improved signal quality.Overall, the BLM18EG221SZ1D is a versatile ferrite chip that is suitable for noise suppression in multiple applications. It offers excellent electrical performance with a high-frequency range from 100MHz - 500MHz and low insertion loss of up to -10 dB. With its high inductance and Faraday cage effect, this component will help to reduce EMI interference and improve the integrity of signal transmission.
