13×15×56×25×42×84×2 mm nanocrystalline cut core, Green Epoxy.

CCNC-13-15-56-25-42-84-002-MFGR is a 13×15×56×25×42×84×2 mm nanocrystalline cut core for industrial PFC inductors, DC reactors, and EV onboard charger inductors. The 13×15 mm limb and 56 mm window length suit bobbin or form-wound coils where an openable core simplifies assembly. Choose this size when Ae, window, and overall length (84 mm) match the target inductor or reactor duty.

industrial DC bus smoothing reactors
medium-frequency power transformers

When to choose this size

This 13×15×56×25×42×84×2 mm cut core (Ae 3.6 cm²) is aimed at industrial PFC inductors and related choke or reactor designs. Step down to the 11×13×40×20×35.5×63×2 mm core when a smaller envelope and lower mass are enough for the inductance and current. Move up to the 19×24×83×35×63.5×122×2 mm core when you need more Ae, a longer window, or higher current/reactor duty than this part supports. In short, pick CCNC-13-15-56-25-42-84-002-MFGR when your design for industrial PFC inductors fits this limb and window; pick a neighbor when power level or envelope shifts the trade-off.

Winding notes

Magnetic calculations should use Ae 3.6 cm² and Le 17.9 cm with the published a–f×R geometry (13×15×56×25×42×84×2 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 13 mm), b (build 15 mm), c (window length 56 mm), d (strip width 25 mm), e (window height 42 mm), and f (overall length 84 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-13-15-56-25-42-84-002-MFGR is typically used for industrial PFC inductors, including EV on-board chargers (typically 3.3–7.2kW 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 19×24×83×35×63.5×122×2 mm core for more Ae or window at higher power. Choose the 11×13×40×20×35.5×63×2 mm core when a smaller envelope is enough.
