❓ Frequently Asked Questions
What are the main advantages of Nanocrystalline cores?
They offer high permeability, high saturation flux density (1.25T), and excellent thermal stability, making them ideal for high-efficiency transformers and EMC filters.
Can you provide customized sizes and shapes?
Yes, we can design and produce high-performance cores according to specific customer requirements, including custom dimensions, inductance levels, and shapes beyond the standard toroidal type.
What is the standard lead time for an order?
Our standard lead time is generally between 25 to 30 days, depending on the order volume and customization requirements.
In which applications are these cores typically used?
They are widely used in switched-mode power supplies (SMPS), UPS systems, solar inverters, frequency converters, and high-speed railway power equipment.
What is the Curie temperature of the material?
The Curie temperature for our Fe-based Nanocrystalline alloy is 560ºC, ensuring reliable performance in high-temperature environments.
Are your cores compatible with international brands like VAC?
Yes, many of our standard products are equivalent to VAC part numbers (e.g., W914, W403, W424) and offer comparable performance in professional applications.
