When to choose this size

Choose CCNT-080-050-030-LFBL when you need this 78.6×50×30 mm powder-coated toroid. Use the bare dimensions for the magnetic path and the finished inner diameter (49.2 mm) for winding clearance.

Winding notes

Magnetic calculations should use the bare 78.6×50×30 mm geometry (Ae 3.52 cm², Le 20.2 cm, stacking factor 0.82). AL is one turn through the window (Kelvin clips) at 0.3 V: 180 µH at 1 kHz, 134 µH at 10 kHz, and 7 µH at 100 kHz. This is not a 2 mT small-signal AL. At 1 kHz this drive saturates the smaller cores. Size the winding to the finished ID 49.2 mm, not the 50 mm bare ID. Saturation is 1.25 T. Core continuous temperature is -40°C to +150°C. Powder-coat temperature class is not published.

Frequently asked questions

Are the stated dimensions bare or finished?

The size in the product name is the bare core (78.6×50×30 mm). Finished coated size is 79.4×49.2×30 mm.

How was AL measured?

One turn: Kelvin clips through the window at 0.3 V. AL is 180 µH at 1 kHz, 134 µH at 10 kHz, and 7 µH at 100 kHz. This is not a 2 mT small-signal AL. At 1 kHz this drive saturates the smaller cores. Verify inductance on the wound part.

Where is a core this size used?

This 78.6×50×30 mm powder-coated toroid is used for high-current transformers and power magnetics where the conductor is large. The 49.2 mm finished window passes a heavy cable or small bus, and the 30 mm height is the largest stack in this powder-coated toroid range.
