Murata 0.85 mm Surface Mount 0805 Chip Ferrite Bead 75 Ω Impedance at 100 MHz BLM21BB750SN1D

Murata BLM21BB750SN1D is a precision-engineered chip ferrite bead designed for surface mounting in electronic circuits. This 0805 size bead provides 75 Ω impedance at 100 MHz, making it an ideal component for EMI suppression filters and high-speed signal line stability.

With dimensions of 2 mm length, 0.85 mm height, and 1.25 mm depth, it fits compact PCB layouts. The ferrite material along with a nickel barrier on the external electrodes ensures excellent solder heat resistance and durability in high temperature environments ranging from -55°C to 125°C.

This component supports a current load up to 700 mA, with a low maximum DC resistance of 160 milliohms, minimizing power loss. Fully compliant with REACH and RoHS standards, it aligns with modern environmental and safety regulations.

The BLM21B series from Murata is recognized for no ground connection requirement and excellent performance in circuits with potentially unstable ground lines. The bead acts as a resistor at noise frequencies without distorting signal waveforms, thus reducing resonance issues commonly encountered in sensitive electronic devices.

This bead is surface mount type packaged in tape and reel form for automated circuit board assembly. Impedance of 75 Ω at 100 MHz provides effective EMI filtering. Current rating of 700 mA enables use in moderate power circuits.

Environmental operating range from -55°C to 125°C supports industrial and commercial applications. Nickel barrier electrodes offer superior soldering reliability. Compact 0805 sized footprint fits densely packed PCBs. Manufactured in Japan, assuring quality and consistency.

This product is commonly used in industrial electronics, communications equipment, and consumer electronics for noise suppression and signal integrity enhancement. It is critical in manufacturing processes requiring reliable EMI filtering components to meet electromagnetic compatibility (EMC) standards.
