Murata’s new BLE32SN series of chip ferrite beads is claimed to be the world’s first chip-type noise suppression components to have 20A current rating. Applications include noise suppression in circuits with large current flows, such as the battery charging systems and powertrains of electric vehicles, plus industrial equipment.
Previously no chip-type noise suppression filter could attain a 20A rating. This meant multiple chips had to be mounted in parallel, adding to BoM costs and taking up board space. By specifying the BLE32SN series, fewer chips will be required (compared to standard 10A noise suppression chips), enabling space savings and weight reductions.
BLE32SN series ferrite beads measure 3.2 by 2.5 by 2mm. Operating temperature range is -55 to 125°C or -55 to 150°C depending on application requirements.
