Product Summary
The BLM18AG221SN1D is an EMI Suppression Filter. It comprises ferrite beads in the shape of a chip. This ferrite bead generates a high impedance which at high frequency mainly consists of a resistance element. The BLM18AG221SN1D is effective in circuits without stable ground lines because the BLM series does not need a connection to ground.
Parametrics
BLM18AG221SN1D general specifications: (1)impedance(at 100MHz/20℃):220±25% ohm; (2)rated current:200mA; (3)DC resistance(max.):0.30ohm; (4)operating temperature range:-55 to +125℃.
Features
BLM18AG221SN1D features: (1)It can be used in digital interface; (2)Resistance of it especially grows in the lower frequency range. Therefore it is less effective for digital signal waveform at low frequency range and can suppress the ringing; (3)It generates an impedance from the relatively low frequencies. Therefore it is effective in noise suppression in the wide frequency range(30MHz-several hundred MHz).
