Abstract
A magnetic device (10), suitable for attachment to a substrate, includes at least one sheet winding (24) having a pair of spaced-apart terminations (26), each receiving an upwardly rising portion (28) of a lead (12). The sheet winding terminations and upwardly-rising lead portions, together with at least a portion of the sheet windings, are then encapsulated with masses of insulative material (18, 19 and 34). A ferromagnetic core (20,22) surrounds at least a portion of the sheet windings to impart a desired magnetic property to the device.
