Document 187-1 SMT Power Inductors - DS3316 Series A small footprint, magnetic shielding and high efficiency are features of the DS3316 family of power inductors. They’re ideal for high performance DC-DC converter applications, especially those requiring shielding. Like all Coilcraft surface mount power inductors, these parts 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 5.6 A and rms current ratings as high as 5 A are available. DC resistance as low as 0.021 Ohms keeps power losses to a minimum. In addition to the standard parts shown here, DS3316 inductors in custom values are also available. Coilcraft Designer’s Kit C116 contains samples of each of the standard parts shown.
