Current handling of up to 4.2A compares to much larger inductors. Magnetic shielding provides more design flexibility by permitting tighter component spacing without electromagnetic interference. The Coilcraft PFL4514 Series offers inductance values from 1.0 µH to 22 µH and an operating temperature range of -40 to +125°C. Typical DCR is as low as 80 milliOhms, enhancing performance in battery-powered devices. Where even lower DCR and higher current is required, a 0.3mm taller part, the PFL4517 Series, is available with DCR starting at 40 milliOhms and saturation current ratings up to 6.5 A. Inductance values for the PFL4517 range from 0.68 µH – 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.
