Nanocrystalline cut core 19×24×83×35×63.5×122×2 mm
19×24×83×35×63.5×122×2 mm nanocrystalline cut core, Green Epoxy.
CCNC-19-24-83-35-63P5-122-002-MFGR is a 19×24×83×35×63.5×122×2 mm nanocrystalline cut core for solar string/central inverter reactors, EV charging station reactors, and industrial motor-drive DC chokes. The 19×24 mm limb and 83 mm window length suit bobbin or form-wound coils where an openable core simplifies assembly. Choose this size when Ae, window, and overall length (122 mm) match the target inductor or reactor duty.

- high-power traction converter chokes
When to choose this size
This 19×24×83×35×63.5×122×2 mm cut core (Ae 6.12 cm²) is aimed at solar string/central inverter reactors and related choke or reactor designs. Step down to the 13×15×56×25×42×84×2 mm core when a smaller envelope and lower mass are enough for the inductance and current. This is the largest published cut-core option: pick it for high-power EV, solar, or industrial reactor stages. In short, pick CCNC-19-24-83-35-63P5-122-002-MFGR when your design for solar string/central inverter 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 6.12 cm² and Le 26.7 cm with the published a–f×R geometry (19×24×83×35×63.5×122×2 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 19 mm), b (build 24 mm), c (window length 83 mm), d (strip width 35 mm), e (window height 63.5 mm), and f (overall length 122 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-19-24-83-35-63P5-122-002-MFGR is typically used for solar string/central inverter reactors, including high-power EV fast-charging station reactors (typically 10–30kW+ per module class). The openable cut-core form simplifies bobbin winding and assembly compared with a closed toroid.
When should I choose a different size instead?
Stay with this size for higher-power reactor duty. Step down to the 13×15×56×25×42×84×2 mm core only when mass and envelope must shrink.
