Description

Technical Field

[0001] The utility model relates to the technical field of filter cover plates, in particular to a high-sealing composite filter cover plate. Background Art

[0002] The filter is a filter circuit composed of capacitors, inductors and resistors. The filter can effectively filter out the frequency point of a specific frequency in the power line or the frequency outside the frequency point to obtain a power signal of a specific frequency, or eliminate the power signal after a specific frequency.
