10×10×33×20×31×53×2 mm nanocrystalline cut core, Green Epoxy.

CCNC-10-10-33-20-31-53-002-MFGR is a 10×10×33×20×31×53×2 mm nanocrystalline cut core for DC-DC converter output chokes, small telecom power inductors, and adapter/charger chokes. The 10×10 mm limb and 33 mm window length suit bobbin or form-wound coils where an openable core simplifies assembly. Choose this size when Ae, window, and overall length (53 mm) match the target inductor or reactor duty.

Applications and selection

Applications

DC-DC converter output chokes

auxiliary UPS inductors
telecom DC-DC converter output inductors (typically 50–150W class)
USB-C PD fast-charger chokes
small high-frequency energy-storage inductors

When to choose this size

This 10×10×33×20×31×53×2 mm cut core (Ae 1.6 cm²) is aimed at DC-DC converter output chokes and related choke or reactor designs. Step down to the 9×9×32×15×28×51×2 mm core when a smaller envelope and lower mass are enough for the inductance and current. Move up to the 10.8×13×40.5×25×35.5×62×2 mm core when you need more Ae, a longer window, or higher current/reactor duty than this part supports. In short, pick CCNC-10-10-33-20-31-53-002-MFGR when your design for DC-DC converter output chokes fits this limb and window; pick a neighbor when power level or envelope shifts the trade-off.

Winding notes

Magnetic calculations should use Ae 1.6 cm² and Le 12.8 cm with the published a–f×R geometry (10×10×33×20×31×53×2 mm). The cut faces (gap view, R=2 mm) must mate cleanly after winding; keep clamping consistent to avoid gap variation and audible noise. Nanocrystalline cut cores suit gapped or low-reluctance inductor designs within 1.25 Tesla and -40°C to +130°C; stay inside the epoxy coating temperature capability for continuous duty.

Frequently asked questions

What do the a–f dimensions mean?

Published geometry uses a (tongue width 10 mm), b (build 10 mm), c (window length 33 mm), d (strip width 20 mm), e (window height 31 mm), and f (overall length 53 mm), with corner radius R=2 mm. Use Ae and Le with this geometry for magnetic design.

Is this cut core suitable for chokes and reactors?

Yes. CCNC-10-10-33-20-31-53-002-MFGR is typically used for DC-DC converter output chokes, including telecom DC-DC converter output inductors (typically 50–150W class). The openable cut-core form simplifies bobbin winding and assembly compared with a closed toroid.

When should I choose a different size instead?

Choose the 10.8×13×40.5×25×35.5×62×2 mm core for more Ae or window at higher power. Choose the 9×9×32×15×28×51×2 mm core when a smaller envelope is enough.
