ESD&EMI protection


High-speed data communication has found increasing applications in portable devices. Differential signaling standards such as USB 2.0, USB 3.0, MIPI and HDMI are gaining ground very quickly. Common-mode filters are thus usually implemented on fast differential lanes, together with high-performance ESD protection on the connector side.
The WECM seriers common mode filter with ESD protection is the best solution to avoid issues like common mode noise induced by radiated or conducted RF or skew between tracks. It allows a system to improve its EMI robustness.
