Magnetic path

Open by design, and that is the point

A rod has no return leg, so the flux closes through air. Low effective permeability, very high saturation headroom, very low cost — the trade rod cores exist to make.

Rod core — open path

Hard to saturate
IC
A straight rod has no return leg, so the flux closes through air. The effective permeability is low and the part is very hard to saturate, which is exactly why a rod choke holds up on a supply line where a closed core would fold.

Closed core — for comparison

More inductance per turn
IC
A toroid or gapped pair keeps the flux inside the core. You get far more inductance for the same turns and almost no external field — at higher cost, and with a saturation limit that arrives much sooner.
The open path is the trade rod cores exist to make

    Rod Core 4x10

    4 x 10mm rod core choke for general-purpose line conditioning on compact boards.

    Inductance: 1.0uH - 22uH

    Rod Core 5x12

    5 x 12mm rod core choke, the most widely used size in the range. A cost-effective series element for supply and output filtering.

    Inductance: 1.0uH - 33uH

  • Rod Core Chokes

    Rod Core 5x20

    5 x 20mm rod core choke. The longer rod raises inductance without increasing diameter, useful where the footprint is fixed but the filtering is not enough.

    Inductance: 3.3uH - 68uH
