Cores manufactured out of Nanocrystalline material in most cases are a drop in replacement for cores manufactured or designed out of .001" & .002" 80% nickel (Supermalloy®) materials, and can be higher performing. They may also be an ideal substitute for larger ferrite cores, when the application is in the lower frequency range for ferrites, and when flux density and performance over a wide temperature range is a must or has been a problem.
There appears to be no limitation to the types of cores that can be manufactured from Nanocrystalline material: C-cores, E-cores, Uncased Toroids, Cased Toroids, Multiple cuts, Gapped Toroids, etc.
Potential Core Weight Reductions When Operating at 2000 Gauss, 20,000 Hz
This material has the best overall performance over a broad range of frequencies when compared to other available materials, including .001" 80% nickel (Supermalloy®). It's relatively high saturation flux density, combined with its incredible low loss and high permeability through a wide frequency range, makes it useful in many applications such as (but not limited to):
- High frequency or broadband transformers
- Broadband current sensors
- High frequency filter chokes (inductors)
- Pulse transformers
Nanocrystalline Core Ordering Guidelines
Cores up to 6' x 6' and strip widths up to 24.0." We can handle cores exceeding 4000 lbs.
Cores ordered with strip widths of 25mm, 33mm, 45mm eliminate the need for slitting, as the material is supplied in these standard sizes from our supplier. Cores ordered from these sizes cost less because there is no slitting process involved or slitting scrap. Core strip widths can be manufactured as narrow as 0.125".
Virtually no limit on maximum strip width with stacked assemblies . Cores can be supplied as an assembly of multiple cores stacked and bonded together to meet your wide width needs. Stacked cores actually perform better, since the voltage per lamination supported is divided by the number of cores stacked together.
Tolerance on the "D" is ± due to the approximate 1% shrinkage factor that occurs during annealing.
Cores can be ordered with a very thin layer of epoxy, encapsulating the core to help improve handling and to minimize sloughing of outer core layer, which may be important in high voltage or oil filled applications.
