MURATA BLM18AG221SN1D Ferrite Bead, 220 ohm, 0603 [1608 Metric], BLM18A Series, 500 mA, 0.25 ohm, ± 25%

The BLM18AG221SN1D is a SMD Chip Ferrite Bead with 0603 case. It is designed to function nearly as a resistor at noise frequencies, which greatly reduces the possibility of resonance and leaves signal wave forms undistorted. BLM series is effective in circuits without stable ground lines because BLM series does not need a connection to ground. The nickel barrier structure of the external electrodes provides excellent solder heat resistance. BLM_A series generates an impedance from the relatively low frequencies. Therefore BLM_A series is effective in noise suppression in a wide frequency range (30MHz to several hundred MHz).
