New Offline Flyback Transformer Series from Wurth Midcom Reduces Footprint by 30%

Wurth Electronics Midcom Inc. has announced the release of a new series of flyback transformers targeting smart metering applications. The new MID-MHC series meets safety standards requiring high creepage and clearance while significantly reducing the transformer footprint.

The key is an innovative combination of core and bobbin design that employs a modified EP-core on a raised bobbin. The resulting package can support creepage and clearance requirements up to 14mm primary to-secondary and up to 8mm between two secondary outputs. The raised design allows this to occur on a 22.1mm x 15.7mm footprint, which is 30-60% smaller than existing designs using horizontal E-core packages to achieve similar power levels. Additionally, the EP-core design improves noise performance relative to E-core designs.

The MID-MHC series includes universal input offline transformers with one to three outputs of 3.3 to 24V to demonstrate the capabilities of the package. Wurth Electronics Midcom will design custom transformers based on the MID-MHC package to meet individual customer’s applications.
