Murata Ferrite Bead 0.85 mm Surface Mount Chip Bead 470 Ω Impedance at 100 MHz BLM21BD471SN1D

Murata BLM21BD471SN1D Ferrite Bead is a surface mount device with a compact 0.85 mm height and 2 mm length in the 0805 package type. It offers 470 Ω impedance at 100 MHz, making it suitable for high-frequency noise suppression in general electronics.

This chip bead operates with a maximum DC resistance of 0.35 Ω and supports a continuous current rating of 200 mA. It can function effectively over a wide temperature range from -55°C to 125°C, ensuring stable performance in varied environments.

The ferrite construction reduces electromagnetic interference without distorting signal waveforms, thanks to its resistor-like behavior at noise frequencies. The nickel barrier external electrodes enhance solder heat resistance to improve manufacturing reliability during assembly processes.

Designed primarily for general use applications, these beads do not require a ground connection, they are ideal in circuits with unstable ground lines, reducing possible resonance effects.

Compact 0805 package (2 mm x 0.85 mm x 1.25 mm) suitable for surface mount technology. 470 Ω impedance at 100 MHz effective noise attenuation in EMI filters. Wide operating temperature range from -55°C to 125°C for industrial applications.

Low DC resistance of 0.35 Ω minimizes power loss in circuits. Nickel barrier external electrodes provide excellent solder heat protection. Suitable for moderate current applications up to 200 mA. Ferrite material construction ensures effective EMI noise filtering.

This product finds extensive use in industrial electronics, communication devices, automotive electronics (non-automotive grade), and consumer electronics requiring EMI noise suppression.
