BLM18HE102SN1D

The BLM18H series chip Ferrite Bead with a modified internal electrode structure, that minimizes stray capacitance and increases the effective frequency range. The BLM18H series realizes high impedance at 1GHz and is suitable for noise suppression from 500MHz to GHz range. The impedance value of HG/HD-type is about three times as large as that of A/B-type at 1GHz, though the impedance characteristic of HG/HD-type is similar to A/B-type at 100MHz or less. HG-type is effective in noise suppression in wide frequency range (several MHz to several GHz). HB/HD-type for high-speed signal line provides a sharper roll-off after the cut-off frequency. HK-type for digital interface and HE-type for optical pickup modules are effective in suppressing the ringing because resistance especially grows in the lower frequency. The magnetic shielded structure minimizes crosstalk. The thin type (t=0.5mm) ferrite bead is suitable for small and low profile equipment such as DSC and cellular phones.

• Low DC resistance and a large rated current are suitable for noise suppression of the driver circuit
• Excellent direct current characteristics
