In summary, TT Electronics’ HA65A Series is designed for high density switching power applications optimized for consistent high efficiency and “low parasitic” performance using low-loss ferrite core material and helical coil configuration. The HA65A has an inductance measured at 100 kHz, 0.1 VAC without DC current. The part temperature ( ambient + temperature rise ) should not exceed 155°C. The HA65A series is AEC Q200 qualified.
