Frequently asked questions
Are the stated dimensions bare or finished?
The size in the product name is the bare core. Finished dimensions are listed separately when they were measured.
Where is a core this size used?
This 61×250×85×266×20 mm race track core is a long-window common-mode choke. The 250 mm window passes a busbar or a large cable bundle, which is the usual geometry for inverter input filters, busbar EMI filters, and three-phase cable-bundle filters. The 20 mm height keeps the choke low while the long slot clears the conductors.
What finish is on this core?
This core is finished with Black PBT Class B 130C.
