What is Frequency Range for nanocrystalline material 1K107B ?

1K107B is an iron-based nanocrystalline material, and its suitable frequency range generally spans from tens of kilohertz (kHz) to hundreds of kilohertz (kHz). Specific applicable frequencies vary depending on application scenarios, as detailed below:

1. As a Common-Mode Choke Core

When used as a core for common-mode chokes, 1K107B material is typically suitable for a frequency range of 20 kHz to 50 kHz. Within this range, it can fully exhibit its performance advantages, enabling efficient electromagnetic coupling and effective suppression of electromagnetic interference (EMI).

2. As a Magnetic Shielding Sheet

For magnetic shielding sheet applications, the operating frequency of 1K107B material ranges from 50 Hz to 300 kHz. It can effectively reduce energy loss during wireless charging processes, minimize heat generation, and mitigate electromagnetic interference to the surrounding environment.

3. As a High-Frequency Transformer Core

In high-frequency transformer applications, 1K107B material performs well within the frequency range of 10 kHz to 50 kHz. It meets the transformer's requirements for key properties such as permeability and core loss, thereby ensuring efficient energy transmission.

Additional Performance Data

the permeability of 1K107B nanocrystalline ribbons exhibits the following characteristics at different frequencies:

• Permeability ≥ 100,000 at 1 kHz;
• Permeability ≥ 80,000 at 10 kHz;
• Permeability ≥ 30,000 at 100 kHz.

Although the permeability of 1K107B decreases slightly as the frequency increases, it still maintains a relatively high level. This ensures the material retains good application performance across the aforementioned frequency ranges.
