Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to an active filter device with stable supporting feet. Background Art

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

[0003] When the filter is in use, it is placed on a supporting surface, such as a bracket or a machine. However, since ordinary filters have four legs at the bottom, or the entire bottom plane of the filter is supported on a bracket or a machine, the four-leg support method will result in a smaller contact point between the filter and the supporting surface, which is not conducive to stable support of the filter. The entire plane support method will cause the bottom end of the filter to fit closely with the supporting surface, which is not conducive to heat dissipation in the bottom area of ​​the filter.
