Product Summary
The BLM18PG121 is a on-board type (DC) EMI suppression filter. The BLM18PG121 chip ferrite bead BLM series comprises femite beads in the shape of a chip. This ferrite bead generates a high impedance which at high frequencies mainly consists of a resistance element. The BLM18PG121 is effective in circuits without stable ground lines because the device does not need a connection to ground.
Parametrics
BLM18PG121 general specifications: (1)Quantity: 20pcs.; (2)Impedance typ. (at 100MHz, 20 degree C): 120W±25%; (3)Rated Current: 2000mA; (4)DC Resistance max.: 0.05W.
Features
BLM18PG121 features: (1)It can be used in digital interface. Resestance of BLM R especially grows in the lower frequency range. Therefore BLM is less effective for digital signal waveform at low frequency range and can suppress the ringing; (2)It generates an impedance from the relatively low frequencies. Therefore it is effective in noise suppression in the wide frequency range; (3)It can minimize attenuation of the signal waveform due to its sharp impedance characteristics.
