## Description

The KEMET HHBC12-1R0A0028V is a through-hole toroidal differential mode choke designed for high-efficiency noise suppression in power electronics. Featuring an Fe-Si core material, this inductor provides a nominal inductance of 28 µH with a tolerance of ±20%. It is engineered to handle a rated RMS current of 5 A while maintaining a low maximum DC resistance (DCR) of 21.1 mΩ, which minimizes conduction losses and limits temperature rise to a maximum of 25°C during operation. The component is housed in a compact toroidal package with maximum dimensions of 26 mm x 26 mm x 12.1 mm, utilizing 1 mm wire for robust current handling.

This series is optimized for demanding power conversion environments, including DC-DC converters and switching power supply outlets where electromagnetic interference (EMI) mitigation is critical. With an operating temperature range spanning -40°C to +125°C, the HHBC12-1R0A0028V is suitable for industrial and high-reliability applications requiring stable performance under thermal stress. The through-hole mounting configuration, combined with a 9 mm lead spacing, ensures secure mechanical integration into printed circuit board assemblies. This component is RoHS compliant and contains no SVHCs, meeting current regulatory standards for environmental safety in electronic manufacturing.
