Murata 0.85 mm Surface Mount 0805 Chip Ferrite Bead 1000 Ω Impedance at 100 MHz BLM21BD102SN1D

Murata BLM21BD102SN1D is a 0.85 mm high, surface mount 0805 chip ferrite bead engineered for efficient EMI suppression in electronic circuits. It offers 1000 ohms impedance at 100 MHz, making it highly effective in filtering unwanted noise from high-speed signal lines and power supply lines. The ferrite material construction ensures excellent magnetic properties, while the nickel barrier external electrodes provide superior solder heat protection during assembly.

This surface mount device measures 2 mm in length, 0.85 mm in height, and 1.25 mm in depth, making it suitable for compact PCB layouts. It supports a current rating of 200 mA and exhibits a maximum DC resistance of 400 mΩ, which helps maintain signal integrity with minimal power loss. Its operational temperature range from -55°C up to 125°C guarantees reliable use in varied industrial and commercial environments.

The BLM21B series ferrite beads from Murata require no ground connection and act nearly as resistors at noise frequencies, leaving signal waveforms undistorted with reduced resonance risk. This makes them ideal for circuits with unstable ground lines and applications needing stable EMI suppression.

This product meets REACH and RoHS compliance standards, underlining its environmental safety. It is suitable for use across various industries including electronics manufacturing, telecommunications, automotive electronics, and industrial controls, where noise reduction and signal fidelity are critical.
