Radio Frequency Filters
. The metal casing of the filter must ensure good contact with the conductive surface or metal surface of the chassis, and the grounding wire must be properly connected.
. The input and output lines of the filter must be kept apart and must not run in parallel to avoid a reduction in the filter's performance.
. It is best to use twisted-pair cables for the connection lines of the filter, as they can effectively eliminate some high-frequency interference signals.
. The installation position of the filter should be selected at the power inlet to shorten the length of the input line inside the chassis and reduce radiation
Interference.
