Amorphous and Nanocrystalline Gap Cores

High-performance cores engineered for precision inductance and high current loads

TI-Electronic’s amorphous and nanocrystalline gap cores are designed to deliver stable magnetic performance in power applications where DC bias, temperature rise, and current handling are critical factors. These cores feature a customizable air gap, enabling tailored inductance values (AL) and optimized circuit behavior under load.

The cores are available in both amorphous and nanocrystalline materials, giving engineers the flexibility to choose based on performance and cost targets.

✨ Key Advantages

High saturation flux density: Enables large DC bias operation without magnetic saturation
Gap structure: Maintains magnetic stability under heavy load
Low core loss: Minimizes temperature rise and improves energy efficiency
High permeability: Delivers effective inductance with fewer turns
Customizable gaps: Tailored AL values to meet exact application needs

🌋 Typical Applications

Power Factor Correction (PFC chokes)
Output filter inductors in power converters
Solar inverter input/output inductors
Hall effect current sensors

Gap cores are particularly well suited for DC-biased inductors, where conventional ferrites would saturate early. With customizable gaps, these cores are a top choice for high-efficiency magnetics.

🔧 Technical Highlights

Material: Amorphous and nanocrystalline alloy
Custom AL values: Adjusted via precise gap tuning
Typical frequency: 10–100 kHz (depending on application)
Operating temperature: Up to 120 °C continuous
Core finishing: Machined and epoxy coated upon request

Note: AL values are reference measurements at 1kHz, 0.25V. Actual AL depends on gap. Tolerances as agreed in QA terms.
