Nanocrystalline cut core 11×13×40×20×35.5×63×2 mm
11×13×40×20×35.5×63×2 mm nanocrystalline cut core, Green Epoxy.
CCNC-11-13-40-20-35P5-63-002-MFGR is a 11×13×40×20×35.5×63×2 mm nanocrystalline cut core for DC filter reactors, mid-range SMPS output inductors, and solar micro-inverter chokes. The 11×13 mm limb and 40 mm window length suit bobbin or form-wound coils where an openable core simplifies assembly. Choose this size when Ae, window, and overall length (63 mm) match the target inductor or reactor duty.

- DC grid line filters
When to choose this size
This 11×13×40×20×35.5×63×2 mm cut core (Ae 1.8 cm²) is aimed at DC filter reactors and related choke or reactor designs. Step down to the 11×12.5×29.5×20×35×53×2 mm core when a smaller envelope and lower mass are enough for the inductance and current. Move up to the 13×15×56×25×42×84×2 mm core when you need more Ae, a longer window, or higher current/reactor duty than this part supports. In short, pick CCNC-11-13-40-20-35P5-63-002-MFGR when your design for DC filter 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 1.8 cm² and Le 15.4 cm with the published a–f×R geometry (11×13×40×20×35.5×63×2 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 11 mm), b (build 13 mm), c (window length 40 mm), d (strip width 20 mm), e (window height 35.5 mm), and f (overall length 63 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-11-13-40-20-35P5-63-002-MFGR is typically used for DC filter reactors, including solar micro-inverter DC-DC inductors (typically 300–600W 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 13×15×56×25×42×84×2 mm core for more Ae or window at higher power. Choose the 11×12.5×29.5×20×35×53×2 mm core when a smaller envelope is enough.
