Coilcraft: Miniature transformers offer 1,500-Vdc isolation

The Coilcraft LPD5030V SMT transformer has two really outstanding features — 1,500-Vdc winding-to-winding isolation and, at just 5 x 5 x 3 mm, a much smaller size than any similar devices. The part is great for coupled-inductor applications like SEPIC power converters and also for flyback-type power conversion.

The transformer is functional safety listed by UL, and it provides tight coupling, high inductance values from 4.7 to 220 µH, and DCR as low as 0.32 Ω. Plus, you can get this part starting from only $0.75 ea/10,000.
