FeSiAl Alloy Core Type BR372312 Series Parameters Silicon Steel Transformer Core

I. Advantages of BR-Type Metal Powder Cores

1. High Resistivity: The metal powder particles are isolated by an insulating layer (e.g., oxide or polymer), significantly increasing the material's resistivity and reducing eddy current losses at high frequencies, making it suitable for high-frequency applications.

2. Low Loss: In high-frequency conditions (especially within 10 kHz to 1 MHz), BR-type cores exhibit low iron loss and eddy current loss, ensuring high energy efficiency and suitability for high-frequency energy conversion scenarios.

3. High Magnetic Permeability: The initial magnetic permeability (μi) is relatively high, typically ranging from 10 to 30, effectively enhancing inductance while maintaining low residual magnetism to avoid hysteresis loss.

4. Good DC Bias Characteristics: The magnetic permeability degrades slowly in the presence of DC bias current, making it ideal for applications requiring superimposed DC (e.g., power inductors, filters).

5. Temperature Stability: The magnetic permeability and loss remain stable within a wide temperature range (-40°C to 120°C), adapting to extreme environments.

6. Excellent Machinability: Can be fabricated into complex shapes (e.g., toroidal, E-shaped, U-shaped), facilitating winding or integration into circuits.

7. Strong Saturation Resistance: Resistant to magnetic saturation under high magnetic fields, suitable for high peak current scenarios (e.g., energy storage inductors in switching power supplies).
