The SDCW2012-2-900TF with Common Mode Chokes / Filters Signal Line 330mA 0805 RoHS is a signal line filter manufactured by Sunlord. This filter is designed to reduce high frequency electromagnetic interference (EMI) that can disrupt digital circuits. It is rated at 330 milliamp (mA) with a 0805 surface-mount package, and is RoHS (Restriction of Hazardous Substances) compliant. The filter features two-line common mode filters with ferrite chips to reduce the intensity of input and output interference currents. With its low ESR and low impedance, it is ideal for multi-lane data links and other applications requiring low EMI emission.
