Nanocrystalline cut core 11×12.5×29.5×20×35×53×2 mm
11×12.5×29.5×20×35×53×2 mm nanocrystalline cut core, Green Epoxy.
CCNC-11-12P5-29P5-20-35-53-002-MFGR is a 11×12.5×29.5×20×35×53×2 mm nanocrystalline cut core for compact PFC boost inductors, LED driver inductors, and telecom power supply chokes. The 11×12.5 mm limb and 29.5 mm window length suit bobbin or form-wound coils where an openable core simplifies assembly. Choose this size when Ae, window, and overall length (53 mm) match the target inductor or reactor duty.

When to choose this size
This 11×12.5×29.5×20×35×53×2 mm cut core (Ae 2 cm²) is aimed at compact PFC boost inductors and related choke or reactor designs. Step down to the 10.8×13×40.5×25×35.5×62×2 mm core when a smaller envelope and lower mass are enough for the inductance and current. Move up to the 11×13×40×20×35.5×63×2 mm core when you need more Ae, a longer window, or higher current/reactor duty than this part supports. In short, pick CCNC-11-12P5-29P5-20-35-53-002-MFGR when your design for compact PFC boost 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 2 cm² and Le 11.7 cm with the published a–f×R geometry (11×12.5×29.5×20×35×53×2 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 11 mm), b (build 12.5 mm), c (window length 29.5 mm), d (strip width 20 mm), e (window height 35 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-11-12P5-29P5-20-35-53-002-MFGR is typically used for compact PFC boost inductors, including compact single-phase PFC inductors (typically 100–300W 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 11×13×40×20×35.5×63×2 mm core for more Ae or window at higher power. Choose the 10.8×13×40.5×25×35.5×62×2 mm core when a smaller envelope is enough.
