Frequently Asked Questions (FAQ)
-
What is the main advantage of the stainless steel case?
The stainless steel case provides mechanical robustness, corrosion resistance, and acts as an EMI shield, which is particularly beneficial in industrial and automotive environments. -
Can I use this core for high-frequency applications above 100 kHz?
While optimized for up to 100 kHz, the core may still be used at higher frequencies with increased core losses. Please consult our technical team for specific frequency ranges. -
Are the dimensions customizable?
Yes, we offer custom outer diameters, inner diameters, and heights. Please provide your requirements for a tailored solution. -
What is the typical lead time for samples?
Standard samples can be shipped within 7–15 working days, depending on size and customization. Bulk orders follow a negotiated schedule. -
Does the core come with a datasheet?
Yes, a detailed datasheet including B-H curve, core loss curves, and mechanical dimensions is available upon request. -
How does the core loss compare to ferrite cores?
Fe-based amorphous cores typically have lower core losses than ferrite at moderate frequencies (10–100 kHz) and higher saturation flux density, making them suitable for high-power inductors. -
Is the stainless steel case magnetic?
We use non-magnetic stainless steel (300 series) to avoid adding extra losses or affecting the magnetic circuit. -
What packaging options are available?
Cores are packed in reinforced boxes with foam lining to prevent damage during transit. Custom packaging is also possible.
