New Miniature Coupled Power Inductor for Flyback and SEPIC Applications

NOv26_CoilcraftCoilcraft’s new compact PFD3215 series coupled chip power inductors provide high efficiency and improved current handling in a rugged, low-cost part.

The dual-wound PFD3215 features a 1:1 turns ratio and is designed for use in a variety of circuits including flyback, multi-output buck and SEPIC. These versatile inductors can also be used as two single inductors connected in series or parallel, as a wideband transformer or as a common mode choke. Measuring just 3.2 mm by 2.3 mm by 1.5 mm, they are a suitable choice when board space is limited and a low profile is desired. Typical applications include tablets and other battery-operated mobile devices requiring precise voltage regulation, efficient charging, and maximum operating time.

The PFD3215 comes in 8 inductance values from 0.39 uH to 10 uH and current ratings to 2.4 amps.
