Murata Ferrite Bead 0.85 mm Surface Mount 0805 Chip Ferrite Bead 220 Ω Impedance at 100 MHz BLM21PG221SH1D

Murata BLM21PG221SH1D is an 0805 surface mount chip ferrite bead, measuring 0.85 mm in height and designed to provide 220 Ω impedance at 100 MHz. This ferrite bead is engineered for effective EMI suppression in sensitive electronic circuits, helping to reduce noise without distorting signal waveforms.

Its compact dimensions (2 mm length and 1.25 mm depth) make it suitable for dense PCB layouts. The nickel barrier construction on the external electrodes ensures excellent solder heat resistance, enhancing durability during assembly processes.

Operating over a wide temperature range from -55°C to 125°C, this ferrite bead supports up to 2 A of current with a low maximum DC resistance of 45 mΩ, ensuring low power loss. It is made from high-quality ferrite material and complies with RoHS and REACH environmental standards.

The BLM21PG series is qualified to the rigorous AEC-Q200 automotive standard, making it suitable for automotive electronic applications requiring high reliability and performance.

Bearing no ground connection requirement, these beads suppress EMI in circuits with unstable ground lines by acting as resistors at noise frequencies, preventing resonance and preserving signal integrity. Applications include power supplies, EMI suppression filters, and general electronic noise filtering tasks.
