Murata Ferrite Bead 0.85 mm Surface Mount (0805) Chip Ferrite Bead 220 Ω Impedance at 100 MHz BLM21AG221SN1D

Murata BLM21AG221SN1D is a high-quality ferrite bead housed in an 0805 package type with surface mount technology. This chip ferrite bead features a height of 0.85 mm, length of 2 mm, and depth of 1.25 mm, specifically engineered to suppress EMI with an impedance of 220 Ω at 100 MHz frequency. The bead does not require a ground connection and is ideal for circuits with unstable ground lines, reducing signal distortion and resonance possibilities.

The nickel barrier construction of the external electrodes enhances solder heat resistance, making it suitable for automated soldering processes on modern PCB assembly lines. This component operates reliably across a broad temperature range from -55°C to 125°C, accommodating varied industrial and commercial environments.

With a maximum DC resistance of 200 mΩ and a current rating of 200 mA, it ensures minimal impact on signal integrity. The ferrite material composition is selected for optimal noise suppression applicable in EMI filtering for general-purpose electronic devices including power supply circuits and communication equipment.

Murata’s BLM21AG series is RoHS and REACH compliant, reflecting environmental and safety standards. The tape and reel packaging facilitates efficient bulk handling and insertion into manufacturing machinery.
