Amorphous Cut Core AMCC Core Product Description
Characteristic:
- High saturation magnetic induction intensity-reduce core volume;
- Rectangular structure - easy coil assembly;
- Core opening - excellent resistance to DC bias saturation;
- Good stability-can work at -50~130℃ for a long time.
Amorphous C Core AMCC Core Advantage
-
High magnetic permeability
Amorphous cores typically have high permeability, which is a measure of how easily a material can be magnetized. High permeability allows for efficient magnetic coupling and improved performance in applications such as transformers, inductors, and magnetic sensors.
-
Low core loss
Amorphous cores have significantly lower core losses compared to traditional crystalline magnetic cores.This characteristic makes amorphous cores suitable for high-efficiency power conversion applications, such as transformers, inductors, and magnetic components in power electronics.
-
Excellent Temperature Stability
Amorphous cores exhibit excellent temperature stability, maintaining their magnetic properties over a wide temperature range. They can operate reliably at elevated temperatures without significant performance degradation. This characteristic makes amorphous cores suitable for high-temperature applications, where stable magnetic behavior is required.
-
Wide Frequency Response
Amorphous cores have a wide frequency response, covering a broad range of frequencies without significant degradation in their magnetic properties. This characteristic makes them suitable for applications that require operation in a wide frequency range, such as power supplies, inverters, and electromagnetic interference (EMI) filters.
-
High saturation magnetic induction intensity
Amorphous cores possess high saturation flux density, which refers to the maximum magnetic flux density a material can withstand before losing its magnetic properties. This means that amorphous cores can store more magnetic energy and handle higher magnetic fields. The high saturation flux density allows for the design of compact and lightweight magnetic components that can handle high power levels.
