When to choose this size

Choose CCNT-054-038-005-STBN when you need this 54×38×5 mm toroidal core. Use the bare dimensions for the magnetic path and the finished dimensions, when published, for winding clearance.

Winding notes

Magnetic calculations should use the bare 54×38×5 mm geometry. AL, Ae, and Le were not measured for this core. Saturation is 1.25 T.

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 54×38×5 mm tape-wrapped toroid is a flat, large-window core for small current transformers, gate-drive transformers, and sensor cores. The 38 mm window and 5 mm height suit a cable used as a single-turn primary, or a low-profile pulse and isolation winding.

What finish is on this core?

This core is finished with Brown Crepe tape.
