Abstract
A surface mountable, toroid magnetic device is provided, the device having a potting filling the central hole of the toroid. The potting extends axially beyond the base of the toroid to form a contact surface which, in use, contacts a mounting body for the device. Heat generated by the device flows by conduction through walls of the toroid defining the central hole into the potting and then through the contact surface into the mounting body.
