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.

■ Equivalent Circuit

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).

(Resistance element becomes dominant

at high frequencies.)

The small size of BLM03A series (0.6x0.3mm) is

suitable for noise suppression in small equipment such

as PA modules for cellular phones.
