Amorphous Core for Gapless Wideband Constant Inductance Filter Choke

What Is an Amorphous Core for Gapless Wideband Constant Inductance Filter Choke?

An amorphous core for gapless wideband constant inductance filter choke is a type of magnetic component designed for applications where stable inductance is needed across a broad frequency range. These cores are made from iron-based amorphous ribbons and do not require an air gap, making them ideal for high-frequency and high-efficiency applications.

The core material offers:

• High Saturation Flux Density: With a saturation flux density of 1.56 T, it can handle high currents without saturation, making it ideal for power electronics.

• Low Core Loss: This results in less heat generation and improved overall system efficiency, especially important in high-frequency applications.

• Excellent Frequency Characteristics: It maintains stable inductance over a wide frequency range, from low to high frequencies, ensuring reliable performance for filtering and smoothing applications.

• Superior Temperature Stability: Operates efficiently over a wide temperature range from –50°C to +120°C, ensuring long-term reliability and stability in various environmental conditions.
