SRN Series: Semi-Shielded Inductors
Bourns Inc.
This tutorial will introduce three new magnetic epoxy shielded inductor models and will provide an overview of their construction and specifications. It will also compare several characteristics of non-shielded, semi-shielded, and shielded inductors side-by-side. Finally, a part number cross reference will be provided for users who would like to test the performance of comparable inductors with different levels of magnetic shielding.
