Patent number: 10361022Abstract: A low profile, small size and high performance electronic device for use in, e.g., electronic circuits which provides maximum creepage and/or clearance distances. In one embodiment, the device is configured for a small footprint and utilizes two or more windings that require isolation. The exemplary device includes a self-leaded header made from a unitary construction which comprises a generally a box-like support body having a cavity for mounting a circuit element with primary and secondary windings, the support body having a base and a plurality of leads extending generally horizontally outward from the support body adjacent the base, the support body having one side opening on a side with leads permitting the loading of the inductive device in the cavity, and a routing channel residing on the top of the base, so as to maximize the creepage and clearance distance of the electronic device. Shaped-core and other embodiments are also disclosed.Type: GrantFiled: September 17, 2018Date of Patent: July 23, 2019Assignee: Pulse Electronics, Inc.Inventor: James Douglas Lint
