Abstract

An inductive device may include a pair of half-shell magnetically-conductive housings joined together and defining an enclosed cavity between them. The inductive device may also include primary and secondary windings provided spatially within the cavity providing magnetic coupling between them. The windings may be electrically insulated from each other and terminals of the primary and secondary windings may traverse to an exterior of the inductive device.

Description

[0001] Priority statement [0002] This application claims priority of U.S. Provisional Application No. 61 / 889206 filed on October 10, 2013, the entire content of which is incorporated herein by reference. Technical field [0003] The subject of this application relates to small electrodynamic inductors and transformers and methods of manufacturing these devices. The application also relates to printed circuit boards and methods for manufacturing inductive devices. Background technique [0004] The transformer is used to transfer energy through inductive coupling between the two sets of windings of the transformer. For example, the transformer may allow the voltage and / or current of the alternating magnetic coupling coil to be increased or decreased. The ratio of the primary winding to the secondary winding determines the step rate in an ideal transformer. [0005] Depending on the specific application, the transformer is manufactured in different sizes. Small transformers have be...
