Class-D Power Inductors offer a wide selection of dual inductors and toroidal power filter inductors for use in Class-D amplifiers. These amplifiers extend battery life in DC-powered audio applications, such as those in automotive sound systems. The dual inductors and toroidal power filter inductors are designed for low distortion and high sound quality. The dual inductors significantly improve the performance of the class-D output LC filters and are housed in a single shielded package to save critical board space. These inductors are AEC-Q200 grade 1 qualified, RoHS compliant, and REACH compliant.
