The FDCW2012 series of wire wound chip common mode choke coils offers excellent noise suppression performance with high common mode impedance at high frequencies. These coils are designed in a compact and low-profile 2.0*1.2*1.2 mm package, making them suitable for space-constrained applications. They are 100% Lead (Pb) & Halogen-Free and RoHS compliant, ensuring environmental responsibility. Applications include power switches, servers, telecommunication equipment, USB communication, panel links for LCD panels, and countering common mode noise in high-speed lines.
