What is an Amorphous C-Core?
Our Amorphous C-Core is a high-performance magnetic core made of iron-based amorphous alloy, precisely shaped into a “C” profile. It’s optimized for power electronics filters, especially solar inverter output inductors and EMI suppression chokes. Amorphous materials offer a non-crystalline structure that delivers high permeability, elevated saturation flux, and significantly reduced core loss—critical advantages in inverter applications.

Key Features
-
High Saturation Flux (≈1.56 T)
Enables compact core designs, reducing size and weight by minimizing the required magnetic volume.
-
Ultra-Low Core Loss at High Frequency
Ideal for 20–100 kHz inverter switching ranges, offering efficient performance and lower thermal stress.
-
Form Factor & Coil Winding Ease
Rectangular “C” shape accommodates tight winding, simplifies coil placement, and supports higher fill-factors—no additional sleeving required.
-
Air-Gap for Bias Immunity
Built-in air gap ensures excellent DC-bias handling, preventing early saturation under high current conditions.
-
Broad Thermal Stability
Reliable operation from –55°C to +130°C with low temperature-induced loss changes.
Typical Applications
-
-
-
Output Filters & Inductors: Reduces ripple and smooths inverter output, with excellent performance at high switching frequencies.
-
EMI Chokes (Common and Differential Mode): High μₑ suppresses electromagnetic noise across a broad frequency band.
-
PFC & Medium-Frequency Transformers: High saturation enables smaller, more efficient power-stage magnetics.
