MICROMETALS ST83-267 Toroidal Cores

Composite Cores

Typical Applications: These Ferrite/Iron Powder Composite Cores produce a large change in inductance with DC bias such that 10 to 20 times more inductance will exist at low current than at maximum current. This characteristic is particularly useful for producing DC output chokes for switching power supplies that must maintain continuous operation to very low loads as well as some EMI Filter applications. See DC energy storage curves.
