Product Summary

The BLM18PG121SN1D is a on-board type (DC) EMI suppression filter. The BLM18PG121SN1D 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 BLM18PG121SN1D is effective in circuits without stable ground lines because the BLM18PG121SN1D does not need a connection to ground.

Parametrics

BLM18PG121SN1D absolute maximum ratings: (1)Quantity: 20pcs.; (2)Impedance typ. (at 100MHz, 20 degree C): 120W±25%; (3)Rated Current: 2000mA; (4)DC Resistance max.: 0.05W.

Features

BLM18PG121SN1D 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.
