Coilcraft UA801x Dual Inductors
Coilcraft UA801x Dual Inductors are developed for Texas Instruments TPA3220, TPA3244, and TPA3245 amplifier evaluation modules. These dual inductors are used in class-D output filters. The single shielded package contains both coils in the inductors. These UA801x inductors offer a very low coupling coefficient (k<0.001) between the two inductors. The UA801x dual inductors are designed for 100W into a 4Ω load and are AEC-Q200 grade 1 qualified. These inductors significantly improve the performance of the output LC filter and reduce the board area with a compact single shielded package. Applications include handheld audio devices/portable docking stations, high-end TV soundbars, and automotive stereo audio systems.
