TT Electronics — AEC-Q200 Certified Flyback Transformer Targets Demanding High Temperature Automotive and Industrial Applications


The high isolation voltage HA00-10043ALFTR transformer provides reference design compatibility with Broadcom (Avago) ACPL-32JT and ACPL-302J optocoupler ICs.

The HA00-10043ALFTR flyback transformer offers high voltage isolation between primary and secondary windings, coupled with AEC-Q200 Grade 0 automotive certification and an operating temperature specification of -40°C to +155°C; this transformer is ideal for use in harsh automotive and industrial environments, such as near a vehicle’s powertrain.

The HA00-10043ALFTR is specifically designed to comply with the regulatory safety requirements stipulated for use with Broadcom (Avago) ACPL-32JT and ACPL-302J optocoupler ICs. Additionally, the superior quality of TT Electronics’ magnetics products ensures a high saturation current capability and low leakage inductance performance. Together with the transformer’s small 12.0 x 12.5mm footprint and low 6.3mm profile, these features provide the perfect solution for high efficiency DC/DC converter applications.

The miniature construction of the HA00-10043ALFTR uses a compact wound bobbin mounted on a 10-pin small-outline (SO) style IC package that enables convenient surface mount assembly. It is supplied in tape and reel packaging in reel quantities of 550 pieces.
