Murata Ferrite Bead 0.85 mm Surface Mount 0805 Package, 120 Ω Impedance at 100 MHz BLM21BB121SN1D

Murata BLM21BB121SN1D is a surface mount ferrite bead in an 0805 package (2 mm length, 0.85 mm height, 1.25 mm depth) designed for EMI suppression in high-speed signal lines and high current circuits. Featuring a 120 Ω impedance at 100 MHz, this chip ferrite bead effectively attenuates electromagnetic interference while maintaining signal integrity.

The device operates over a wide temperature range from -55°C to 125°C, making it suitable for demanding industrial and commercial applications. The ferrite material provides stable magnetic properties and durability, while nickel barrier external electrodes ensure excellent resistance to solder heat, improving assembly reliability.

This ferrite bead has a maximum DC resistance of 190 mΩ and supports a current rating of up to 600 mA, which minimizes power loss while filtering noise. It is supplied in Tape & Reel packaging, facilitating efficient automated PCB assembly processes.

Murata's BLM21B series beads do not require a ground connection, making them ideal for circuits with unstable ground lines. They act almost like resistors at noise frequencies, preventing resonance and preserving signal waveform integrity. The BLM21BB121SN1D variant is tuned specifically for mid-frequency EMI suppression applications.

This product is RoHS and REACH compliant, and its country of origin is Japan, ensuring environmental and quality standards compliance. Compact 0805 surface-mount device ideal for compact PCBs. 120 Ω impedance at 100 MHz for efficient EMI noise filtering.

Supports a continuous current of 600 mA for high-current circuits. Wide operating temperature range of -55°C to 125°C for harsh environments. Low DC resistance reduces power loss in sensitive circuits. Nickel barrier electrodes provide solder heat protection during manufacturing.

Designed for use in high-speed signal lines and EMI suppression filters. RoHS and REACH compliant ensuring environmental safety. Japan-made product guaranteeing high manufacturing quality.

Murata Ferrite Beads like the BLM21BB121SN1D are widely used in electronics manufacturing, automotive, telecommunications, and computing industries. They provide essential noise filtering to improve signal integrity and reduce electromagnetic interference in sensitive circuits.
