SMD 0805 Ferrite Filters- BLM21A Series
BLM series ferrite beads from Murata do not require a ground connection and are Ideal for use in circuits with unstable ground lines. At noise frequencies, these ferrite beads are designed to function nearly as resistors, leaving signal wave forms undistorted and reducing the possibility of resonance. The nickel barrier construction of the external electrodes enables excellent solder heat resistance.
This series of ferrite beads are designed for general use applications.
