Wire Wound Common Mode Choke YJYCOIN YLM1211-202T Offering EMI Noise Suppression for LED and Monitor

Wire Wound Common Mode Choke - YLM1211 Series

The YLM1211 Series is a line of wire wound common mode chokes designed with SMD construction for a low profile. These chokes offer high impedance and excellent frequency characteristics, along with self-electromagnetic shielding and low magnetic flux leakage. They are suitable for applications such as LED lighting, TV games, and monitors, primarily for mitigating EMI common-mode noise.
