Abstract
An inductor comprises a central core 1 having bevelled upper and lower edges. The core is surrounded by a coil or winding 3, and the magnetic circuit is completed by complimentary half shells 5 and 6 that surround the coil and mate with the bevelled core edges but which are separated therefrom by compressible films 4. Flanged assembly brackets 7 and 8 complete the structure and may be inwardly pinched to compress the films and thereby adjust the inductance value to a desired level. The void spaces 9 and 10 at the top and bottom of the core help to channel the flux through the shells 5 and 6.
