Document 180-1 SMT Power Inductors – DT3316P Series These magnetically shielded inductors are designed for a wide variety of applications, including board mounted DC-DC converters, miniature power supplies and voltage multiplying circuits. They function equally well in filter and smoothing circuit applications. The Coilcraft DT Series is specially designed to provide the low-loss benefit of ferrite, with a soft saturation characteristic, allowing best performance at both light load and high peak current conditions. For new designs, consider the MSS7341, MSS1038 or MSS1260 as alternatives to this series. These series are more cost effective and offer better current handling. In addition, the MSS7341 is a significantly smaller part. We will continue to manufacture and support the DT3316P indefinitely.
