The BLE32SN line of chip ferrite beads has been introduced by Murata. These are allegedly the first chip-type noise-suppression components with a 20A current rating in existence. They will be used to provide noise reduction in industrial equipment as well as circuits with high current flows, including the battery charging systems and powertrains of EVs. A 20A current rating for a chip-type noise reduction filter was previously unattainable. Since many chips had to be mounted simultaneously, the BoM prices increased and precious board space was used. A smaller number of chips will be needed when the new series is specified, which will result in weight and storage space savings.
The company’s experts have been successful in creating a unique internal electrode design utilizing cutting-edge structural modeling techniques. By doing this, these chips’ electrode volume is increased in comparison to those using a standard configuration. Their DC resistance traits have significantly decreased as a result. Because the amount of heat generated is reduced, less thermal management is needed, which results in additional cost and weight reductions. With dimensions of 3.2mm x 2.5mm x 2mm, this series of ferrite beads has a small form factor. Depending on the application requirements of the clients, they can support an operational temperature range of -55C to +125C or -55C to +150C.
