On-Board Type (DC) EMI Suppression Filters (EMIFILr) Chip Ferrite Beads BLM03/BLM15/BLM18/BLM21/BLM31/BLM41 Series Features (BLM_A Series) The chip ferrite beads BLM series is designed to function nearly as a resistor at noise frequencies, which greatly reduces the possibility of resonance and leaves signal wave forms undistorted. The BLM series is effective in circuits without stable ground lines because the 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). The small size of BLM03A series (0.6x0.3mm) is suitable for noise suppression in small equipment such as PA modules for cellular phones. 1 Equivalent Circuit (Resistance element becomes dominant at high frequencies.)
