Overview

The Coilcraft DO3316P-332MLB is a high-performance, unshielded surface-mount power inductor designed for demanding DC-DC converter applications. Its primary function is to store energy and smooth current ripple, with a critical operational characteristic being its 5.4A maximum DC current rating, which dictates its suitability for moderate power levels. A key design consideration for this ferrite drum core inductor is the trade-off between its 20% inductance tolerance and its relatively low DC resistance (15 mOhms). While the wider tolerance simplifies manufacturing and potentially lowers cost, designers must account for this variation in their control loop stability calculations and ensure adequate margin.

Key Features
