SMT Power Inductors - LPO3310 Series
The LPO33310 power inductor is a
mere 3,3 mm square by 1 mm high.
It is perfect for low-profile applica-
tions with tight board space con-
straints such as mobile phones, digi-
tal cameras, PDAs and other hand-
held equipment.
Despite their small size, these induc-
tors have very high saturation current ratings: up to
2.8 Amps! The specially designed ceramic case com-
pletely protects the windings and provides the best
possible surface for pick and place handling.
Coilcraft Designer’s Kit C175 contains samples of all
values shown. To order, contact Coilcraft or purchase
