They are used in input filters applied in power supply systems. They consist of a ferrite core with oppositely wound windings, so that the operating currents cancel each other out, while common mode interference is effectively suppressed.They are characterized by small dimensions, a compact design, and stable operating parameters, and can be mounted directly on printed circuit boards.

Inductance: 2x1mH
Inductance tolerance: ±20%
RDC: 2×0,018Ω
Resistance tolerance: ±20%

They are made using toroidal cores of powdered metal, suitable for operation in both AC and DC circuits. These cores are characterized by low initial permeability and a distributed air gap, which ensures high resistance to saturation and stable inductance over a wide current range.

These chokes feature a compact design, stable operating parameters, and the possibility of direct mounting on printed circuit boards.

Current: 2,2A
Inductance: 33µH
Inductance tolerance: ±20%
RDC: 0,032Ω
Resistance tolerance: ±20%
