Murata Ferrite Bead Surface Mount 0805 Package, 0.85 mm Height, 68.4 Ω Impedance at 25 MHz, 120 Ω at 100 MHz BLM21AG121BH1D

Murata BLM21AG121BH1D is a chip ferrite bead designed for surface mount applications, packaged in the 0805 size with dimensions of 2 mm length, 0.85 mm height, and 1.25 mm depth. This ferrite bead provides effective EMI suppression and general-purpose noise filtering capabilities in high-frequency electronic circuits.

The bead exhibits an impedance of 68.4 Ω at 25 MHz, increasing to 120 Ω at 100 MHz and further to 150 Ω at 300 MHz, making it highly effective across a broad frequency range. Its low maximum DC resistance of 0.09 Ω allows it to be used in circuits with current ratings up to 10 mA without significant power loss.

Constructed from ferrite material, the bead operates efficiently within harsh temperature environments from -55 °C to 150 °C and is designed for reliable solder heat resistance with nickel barrier external electrodes. It is suitable for circuits lacking a stable ground line and can handle high current applications due to its low DC resistance.

This component complies with international environmental standards including RoHS and REACH, ensuring safety and eco-friendliness. The product also meets the demanding Automotive AEC-Q200 standards, enabling its use in automotive electronics requiring high reliability.
