Product Description
Stable Ferrite Core SQ28 Common Mode Inductor for Reliable Signal Noise Filter
Industrial Performance Leader: SQ28 Series High-Current Common Mode Choke
The SQ28 Series Common Mode Inductor represents a high-efficiency solution for electromagnetic interference (EMI) suppression in modern power electronics. Engineered with advanced Mn-Zn ferrite material science and precision-controlled winding processes, this component provides stable impedance characteristics under substantial current loads, preventing saturation collapse that often plagues inferior EMI filters.
Key Product Features
- High-Mass Square Core Technology: Larger effective magnetic path area for superior noise rejection without premature core saturation
- Massive Current Capacity: Handles continuous currents up to 15A with minimal internal heat generation
- Exceptional EMI/EMC Suppression: Optimized for common-mode noise attenuation from 10kHz to 10MHz
- Integrated Mechanical Stability: Reinforced vertical mounting base withstands mechanical shock and vibration
- Total Galvanic Isolation & Safety: High-dielectric insulation barriers withstand grid-side transients up to 3000V AC+
- Optimized Thermal Management: Vertical structure allows natural convection airflow for safe operating temperatures

Advanced Manufacturing Features
The SQ28 Series features Square-Core Closed Magnetic Circuit technology that forms a tightly coupled magnetic loop, trapping magnetic fields within the ferrite to eliminate external shielding requirements. Precision Automated Winding Technology prevents wire overlapping and insulation abrasion, while Vacuum Pressure Impregnation creates a moisture-proof, monolithic component resistant to industrial gases and magnetostriction.
