Document 303-1 SMT Power Inductors - DH3316 Series These power inductors feature a small footprint, magnetic shielding and very high efficiency, making them ideal for high performance DC-DC converter applications. Like all Coilcraft surface mount power inductors, they are designed with a flat top for reliable pick and place operations. The terminations wrap around the end of the base, ensuring a sound solder fillet and simplifying inspection. Saturation current ratings up to 10 A and rms current ratings as high as 6 A are available. Very low DC resistance keeps power losses to a minimum. In addition to the standard values shown here, DH3316 inductors in custom values are also available. For free evaluation samples or to order, contact Coilcraft or visit www.coilcraft.com.
