Features: No filter is guaranteed to eliminate all interference. A filter is most effective when the interference source on the electric path corresponds with the filter frequency. Adding a filter generally improves equipment stability and may help prolong equipment service life. Notice: The filter must be connected to ground wires; otherwise, performance may be reduced by up to 50%.
