Nanocrystalline cut core 10.8×13×40.5×25×35.5×62×2 mm
10.8×13×40.5×25×35.5×62×2 mm nanocrystalline cut core, Green Epoxy.
CCNC-10P8-13-40P5-25-35P5-62-002-MFGR is a 10.8×13×40.5×25×35.5×62×2 mm nanocrystalline cut core for DC-link reactors, PFC inductors, and solar micro-inverter reactors. The 10.8×13 mm limb and 40.5 mm window length suit bobbin or form-wound coils where an openable core simplifies assembly. Choose this size when Ae, window, and overall length (62 mm) match the target inductor or reactor duty.

When to choose this size
This 10.8×13×40.5×25×35.5×62×2 mm cut core (Ae 2.3 cm²) is aimed at DC-link reactors and related choke or reactor designs. Step down to the 10×10×33×20×31×53×2 mm core when a smaller envelope and lower mass are enough for the inductance and current. Move up to the 11×12.5×29.5×20×35×53×2 mm core when you need more Ae, a longer window, or higher current/reactor duty than this part supports. In short, pick CCNC-10P8-13-40P5-25-35P5-62-002-MFGR when your design for DC-link reactors fits this limb and window; pick a neighbor when power level or envelope shifts the trade-off.
Winding notes
Magnetic calculations should use Ae 2.3 cm² and Le 15.1 cm with the published a–f×R geometry (10.8×13×40.5×25×35.5×62×2 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 10.8 mm), b (build 13 mm), c (window length 40.5 mm), d (strip width 25 mm), e (window height 35.5 mm), and f (overall length 62 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-10P8-13-40P5-25-35P5-62-002-MFGR is typically used for DC-link reactors, including industrial power supply PFC inductors (typically 500W–1.5kW 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 11×12.5×29.5×20×35×53×2 mm core for more Ae or window at higher power. Choose the 10×10×33×20×31×53×2 mm core when a smaller envelope is enough.
