Murata BLM21BB471SN1D is a high-performance SMD 0805 ferrite bead engineered for EMI (Electromagnetic Interference) suppression in modern electronic circuits. Featuring a compact 0.85 mm height by 2 mm length and 1.25 mm depth, this ferrite bead integrates easily on PCBs with board mount type packaging.
The ferrite bead offers 470 Ω impedance at 100 MHz and rises to 700 Ω at 1 GHz, effectively attenuating high-frequency noise signals in sensitive electronic assemblies, particularly suited for high-speed signal lines. With a current rating of 200 mA and a maximum DC resistance of 0.45 Ω, the bead ensures minimum power loss while maintaining EMI protection.
Constructed from high-quality ferrite material, it is designed for operating temperature ranges from -55°C to 125°C, making it reliable in a wide range of industrial, communication, computing, and consumer electronics applications.
The BMB-B series ferrite bead minimizes waveform attenuation due to sharp impedance characteristics and provides wide frequency coverage for effective EMI filtering. High soldering heat resistance guarantees durability during PCB assembly processes.
This product complies with RoHS and REACH environmental standards, supporting regulatory requirements for manufacturing and end use. Manufactured in Japan, it reflects Murata's industry-recognized quality and reliability standards in passive components.
The bead fits compact and space-constrained PCB designs with 0805 package dimensions. It is effective in reducing noise in automotive, industrial, communication, and consumer electronic signal lines. Excellent choice for noise suppression in power circuit lines of electronic devices.
For engineers and designers looking for a reliable, compact EMI filter solution, the Murata BLM21BB471SN1D ferrite bead offers proven performance and manufacturing stability. The product is ideal for use in high-speed digital circuits, communication devices, and sensitive electronic modules requiring stringent EMI control.
