CDRH127NP-180MC – TBC

Overview

The Sumida America Components Inc. CDRH127NP-180MC is a shielded power inductor designed for efficient energy storage and filtering in demanding electronic circuits. Its core strength lies in its robust shielding, which significantly mitigates electromagnetic interference (EMI) leakage, a critical consideration in high-density power supply designs where proximity to sensitive analog or RF circuitry is common. While its 3.9A current rating and low 39.2mΩ DCR are impressive, designers must carefully balance the inductor’s physical footprint (12mm x 12mm x 8mm) against the thermal dissipation requirements, as higher current densities can lead to increased core and winding losses.
