Product Introduction:DO3316P-223MLD Product Introduction

The DO3316P-223MLD from Coilcraft is a 22µH shielded power inductor rated for 3.1A with 80mΩ DCR in a SMD package. It is designed for high-efficiency DC-DC converter applications requiring low EMI and high saturation current.

Working Principle:DO3316P-223MLD Working Principle

The inductor stores energy in its magnetic field when current flows through the winding. In a buck converter, the inductor smooths the pulsed switch output into a continuous DC current. The shielded construction contains the magnetic flux within the core, minimizing EMI coupling to nearby circuits.
