Description :

Document 178-1 SMT Power Inductors – DT1608 Series The Coilcraft DT1608 Series represents the ultimate in cost-effective, miniature power inductors. The DT Series is magnetically shielded and the materials used provide natural heat sinking. This allows these parts to be used at relatively high currents. Even at 150% of rated current, the temperature rise is less than 15°C. Because of their “swinging” inductance vs current characteristics, the DT1608 Series can be used as ultra high L inductors at zero or low current. For free evaluation samples or to order, contact Coilcraft or visit www.coilcraft.com.
