Planar E Cores

Bunting Magnetics Europe > Soft Magnetics > Soft Ferrites > Components > Planar E Cores

Many new electronics equipment will use switched mode power supplies where the voltage transformation unit it integrated on a circuit card. As cards may be racked with minimal clearances, low profile components are necessary. Planar assemblies differ radically from conventional transformers as wire windings are replaced by stacks or flat spiral laminations. In some cases the winding can be replaced by printing circuit tracks, with the E core inserted through the board. The planar E core’s low profile shape and ease of construction offers significant advantages including: Fast error-free winding; excellent heat sinking properties and efficient repeatable performance at low cost. All the cores adhere to specifications laid down in IEC 62317-9
