Product Description
Product Overview
Wire Wound Chip Common Mode Choke Coils are miniature, surface-mountable filters designed for high-density applications. They feature a large coupling coefficient, minimizing impact on high-speed differential signals while effectively suppressing high-frequency common mode noise. Available in a range of impedances from 67 to 2200, these filters are suitable for various noise levels and signal frequencies. Key applications include USB lines for PCs and peripherals, LVDS lines for laptops and LCDs, and USB lines for digital AV equipment.
