When to choose this size

Choose CCNRT-055P5-165P5-065P5-175P5-015-STBK when you need this 55.5×165.5×65.5×175.5×15 mm race track 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 55.5×165.5×65.5×175.5×15 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 55.5×165.5×65.5×175.5×15 mm race track core is a low-profile common-mode choke. The 165.5 mm window (163.5 mm finished) passes a cable bundle or flat conductors, which suits EMI line filters, inverter input filters, and low-profile cable chokes where a round toroid cannot clear the bundle.

What finish is on this core?

This core is finished with Black Crepe tape and electrical tape.
