Lineup of Chip Ferrite Beads

Lineup of Ferrite Beads That Support Large Currents up to 20A

We have assembled a lineup of ferrite beads that support large currents as measures against power line noise. In particular, we recommend our BLE32S series, which supports currents up to 20A, the BLM31SN series, which supports currents up to 12A, and other similar series as products for power circuits that handle large currents not supported by existing chip ferrite beads. Moreover, we have also prepared the BLM18SP and other series as a lineup of small products.

Noise Suppression Basic Course

To implement noise suppression in digital devices, it is important to have a good understanding of how noise is generated, how it is transferred, and how it causes problems. This introduction provides basic knowledge related to noise suppression, including the principles of noise generation, various ways that noise is transferred, and the characteristics of noise.
