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.
