Murata BLM21PG220SN1D High-Current Ferrite Bead (22 Ohm @ 100MHz, 6A, 0805 SMD)

Suppress high-frequency power supply noise and EMI in your circuit designs with the genuine BLM21PG220SN1D chip ferrite bead from Murata. Package-designed in a compact 0805 SMD size (2.0 x 1.25 mm), this high-current power line filter delivers 22 Ohms impedance at 100 MHz while boasting an extraordinary rated current capability of 6.0 A with ultra-low DC resistance (<= 9 mΩ).

Part of Murata’s EMIFIL BLM_P series, it is specially optimized for DC power line noise suppression where minimal voltage drop and low heat dissipation are essential. It effectively filters high-frequency ripple and switching transients in power distribution networks (PDN), FPGA/CPU power rails, automotive electronics, battery management systems, and high-current DC-DC converter outputs.

Key Features:

• 6.0 A High Current Rating: Extremely high current capability in a tiny 0805 footprint.

• Ultra-Low DC Resistance (<= 9 mΩ): Prevents voltage drop and minimizes heat buildup under continuous heavy loads.

• Effective EMI Filtering: 22 Ohm impedance at 100 MHz effectively attenuates high-frequency power line noise.

• Compact 0805 Package: Standard 2.0 x 1.25 mm footprint ideal for high-density SMT assembly.
