Product Description

Murata BLM03PX121SN1D is a precision chip ferrite bead designed for advanced EMI suppression in electronic circuits. It measures 0.6 mm in length and 0.3 mm in height, making it ideal for compact and high-density PCB layouts. This 0201 package ferrite bead operates efficiently with impedance values of 55.6 Ω at 25 MHz and 120 Ω at 100 MHz, providing excellent noise attenuation across broad frequency ranges.

The solder mount type bead features nickel barrier external electrodes that exhibit superior solder heat resistance, ensuring reliability during PCB assembly and operational longevity. It operates effectively within a temperature range of -55°C to 125°C, accommodating demanding industrial, automotive, and consumer electronic environments.

Its chip ferrite construction enables it to behave predominantly as a resistor at noise frequencies, reducing resonance risk and preserving signal integrity in circuits without a stable ground. This characteristic makes it particularly useful in high current circuits due to its low DC resistance.

The passive component is supplied in Tape & Reel packaging format, enhancing streamlined manufacturing processes and automated placement during PCB assembly. Compact 0201 package enables use in space-constrained applications.

High impedance across frequency range ensures efficient EMI filtering. Robust temperature tolerance supports industrial and automotive electronics. Nickel barrier electrodes guarantee excellent solder heat stability. Ideal for circuits lacking stable ground connections.

Low DC resistance supports high current applications. Supplied in Tape & Reel packaging for manufacturing efficiency.

This Murata Ferrite Bead is extensively used in electronic assemblies for industrial, automotive, telecommunications, and consumer electronics to improve device reliability and reduce electromagnetic interference.
