Product Overview
Nanocrystalline toroidal cores feature a ring-shaped geometry that provides optimal magnetic flux containment and minimal electromagnetic interference. These donut-shaped transformer cores offer superior performance in space-constrained applications where efficient magnetic coupling and EMI suppression are critical.
Ideal for nanocrystalline common mode choke cores, EMI suppression toroidal cores, and power conversion applications, our cores enable compact designs with 99%+ efficiency in demanding environments from -40°C to +130°C.
The unique nanocrystalline structure, with grain sizes of 10-20 nanometers, provides exceptional magnetic properties that bridge the gap between traditional ferrite and amorphous materials. This revolutionary technology enables transformer designers to achieve unprecedented power density while maintaining excellent thermal stability and long-term reliability in critical applications. For size-ladder R&D packs, see nanocrystalline core kits for design engineers.

Frequently asked questions
What makes nanocrystalline cores superior for EV charging applications?
Nanocrystalline cores offer roughly 10× higher permeability than typical ferrite grades, enabling smaller, lighter magnetics with high efficiency at switcher frequencies up to about 100 kHz in EV onboard chargers and DC-DC stages.
What temperature range can nanocrystalline toroidal cores handle?
Published designs typically cover about -40°C to +130°C with limited permeability drift, suitable for automotive and industrial ambient plus self-heating. Confirm the casing temperature class (for example PBT Class B) for continuous duty.
When should I choose a PBT-cased toroid instead of a cut core?
Use a PBT-cased toroid for common-mode chokes, current transformers, and closed-path EMI or power designs where the winding stays on a continuous ring. Choose a nanocrystalline cut core when you need an openable path, bobbin winding, or a controlled air gap for DC-biased PFC boost inductors and reactors.
Do stocked CCNT parts publish AL and dimensions?
Yes. Each catalog toroid lists bare and finished OD×ID×H where applicable, AL at key frequencies, pack pricing or waitlist status, and product photos or dimension diagrams. Open the SKU page for datasheet download and winding notes.
Can you manufacture custom toroidal sizes?
Yes. Custom OD/ID/H, AL targets, coatings, and casings are available to quote. Use the core designer tool for a starting geometry, then request a quote with frequency, current, and thermal limits.
