ECM Surface Mount Power Inductors
EC63/73/75 Series
Small PCB Area Low 3.0mm Height Option Up to 3 Amp Low Cost Typical Reel Size 1000pcs
The EC63/73/75 surface mount inductors comes in three package sizes with a hight profile as low as 3.0mm. The EC75C (shown above) is ferrite shieled, as is both the EC73C and EC63C. The EC73F and EC75F are open construction. The whole range offers excellent Isat characteristics for their given size along with excellent temperature endurance. Suitable applications include power supplies for VTR,OA equipment, LCD display, and DC/DC converters.
