Product Details
Construction & Process
Strong magnetic shielding: Encased in a heavy-duty shielded core structure, effectively suppressing electromagnetic interference (EMI) and preventing magnetic coupling with adjacent components in dense PCB layouts. Clear laser marking: The top surface features a precisely laser-etched, high-contrast "3R3" inductance marking for instant identification during assembly and quality control.
Core & Winding Design
Flat wire edge-wound structure: Wound with high-grade flat copper wire, maximizing conductor cross-sectional area within a compact package size. This significantly reduces AC resistance and high-frequency skin effect losses. Low-loss high-frequency core: Utilizes advanced high-frequency ferrite material specifically engineered for Class D amplifier filter applications, ensuring minimal core loss and excellent linearity for distortion-free, pure audio signal reproduction.
Terminals & Soldering Details
Heavy-duty terminal pins: Designed with wide pads/terminals, providing excellent mechanical stability on the PCB and withstanding high thermal and mechanical stress in demanding audio power environments. Clean and uniform solder surface: Terminals are perfectly tin-plated with a bright metallic luster, preventing cold solder joints and ensuring ultra-low contact resistance for maximum current transfer.
