The new PFL4514 series of shielded power inductors from Coilcraft allows circuit designers to increase board density without sacrificing efficiency.
These wire-wound surface-mount inductors require a mere 16 mm² of board space and are just 1,4 mm high. They can handle currents up to 4,2 A and magnetic shielding provides design flexibility by permitting tighter component spacing without electromagnetic interference.
The parts offer inductance values from 1,0 μH to 22 μH and an operating temperature range of -40°C to +125°C. Typical DCR is as low as 80 mΩ, enhancing performance in battery-powered devices. Where even lower DCR and higher current are required, a 0,3 mm taller part, the PFL4517 series, is available with DCR starting at 40 mΩ and saturation current ratings up to 6,5 A. Inductance values for the PFL4517 range from 0,68 μH to 10 μH.
These low-profile inductors are magnetically shielded and share a common footprint for design and prototyping flexibility. Composite-core construction and heavier-gauge windings provide high current handling and excellent DCR. The parts are halogen-free and RoHS-compliant, with matte tin over nickel terminations that are compatible with 260°C processing.
