Toroidal surface-mount power inductor

The 8300 Series toroidal surface-mount power inductors are suitable for handheld consumer electronics with a restricted PCB footprint and height — the device measures only 7.8 × 5.20 × 1.8 mm. The inductor’s toroidal core ensures that magnetic flux is confined to the core, so stray fields are almost totally eliminated.

With a device-dependent maximum dc current of 3.0 A, the inductors are available from 0.42 to 100 uH. Dc resistance ranges from 24 to 1,320 mΩ. The device’s operating temperature range is –40 to 85°C. Supplied in tape and reel for high-volume automated surface-mount assembly, the maximum reflow solder temperature is 260°C.
