This document introduces the CDRH series SMD power inductors from Sumida, including three types: CDRH4D18, CDRH4D18C, and CDRH4D18C/LD. The features of the products include small size, low height, custom design options, magnetically shielded construction, and suitability for DC-DC converter inductors in mobile phones, PDAs, MP3 players, HDDs, DSC/DVCs, notebook PCs, etc.
This document provides technical specifications for the Sumida CDRH Series of power inductors, specifically the CDRH4D18, CDRH4D18C, and CDRH4D18C/LD models. These magnetically shielded components are designed for use in DC-DC converters within mobile phones, PDAs, MP3 players, and other electronic devices. The datasheet covers standard and low DCR variants with inductance ranges from 1.0 to 180 µH.
