Advantages

1. High Magnetic Permeability

   Maintains high magnetic permeability under high-frequency conditions, making it suitable for high-frequency circuits. Both the initial permeability (μi) and maximum permeability (μm) are high, effectively enhancing inductance performance.

2. Low Loss

   Lower eddy current loss and hysteresis loss at high frequencies, ideal for high-frequency applications. Reduces energy loss and improves efficiency in high-frequency devices like switching power supplies.

3. Good Frequency Characteristics

   Maintains stable inductance characteristics over a wide frequency range (e.g., 1kHz~1MHz). Suitable for high-frequency filtering, energy storage, and other applications.

4. Excellent DC Bias Characteristics

   Minimal inductance decay under DC bias fields, making it suitable for applications requiring superimposed DC.

5. High Temperature Resistance and Reliability

   Operates over a wide temperature range (typically -40°C~125°C), suitable for harsh environments. High mechanical strength, resistant to deformation or cracking.

6. Good Processability

   Can be fabricated into complex shapes for inductors, such as toroidal or E-shaped cores. Easy to integrate with circuit boards, suitable for automated production.
