Toroidal inductor addresses current affairs

A pair of surface-mount inductors from C&D Technologies provides your design with high current ratings along with low dc resistance. Targeting use in switching supplies and dc/dc converters, these field-retaining inductors handle current up to 8.1A with resistance as low as 14 mΩ. The 4000 series measures 14.1×14.2 mm, is 8.8 mm high, and offers inductance values of 3.3 to 330 µH. The 4100 series measures 16.8×15.5 mm, is 9.9 mm high, and spans 2.7 to 330 µH. The pick-and-place-friendly devices sell for less than $1 (OEM quantities).
