Product Description
Introduction of NOYITO DC power filter circuit:
The circuit consists of three parts, the first part is a one-stage LC filter circuit, the second part is a common mode EMI filter, and the third part is a two-stage LC filter circuit.
LC filter: generally known as passive filter, it is a traditional DC power harmonic compensation device composed of inductors and capacitors, which can filter out harmonics in the power supply one or more times and purify the DC power supply.
Common mode filtering: It can suppress the problem of fast transient group interference with a repetition frequency of several kilohertz in some user sites.
One year after-sale warranty.

I have these connected to a SMPS output. I was seeing 580mv noise spikes from the PS and these units on the output side knock that down to 180 - 200mv, so they are doing what they say. I wish there were more high current choices, but these 20 amp modules are working for me right now. I would also like to see the manufacturer to provide more data on what to expect including a schematic.

Not only is this a very neat little package, it does a solid job of rejecting noise, most specifically the higher frequency noise left over from a SMPSU. I find that most Class-D audio amplifiers benefit considerably from a truly clean supply, and this little module is just the ticket. Ordinarily I’d engineer one myself, but at this price I can’t beat it!

This 3 stage filtering board does a great job of cleaning up the DC voltage from a switching power supply.I had a 3 volt DC switching power supply for a radio. I wanted to use the radio's audio headphone output to go into another device on a permanent basis. With the DC power supply, the headphone output had a fair amount of static and general noise. On battery only, the radio was perfectly clean sounding. Using this filtering board, the noise and static level was eliminated from the power supply. I also added a ferrite core with 3 loops in it after the filtering board (which made very very little difference, but just icing on the cake). As long as you use the correct one for the amount of current you are using (always over the current never under), and keeping the supply voltage at half or below, this product will do a very good job of cleaning up the output voltage of your switching power supply.

The picture makes it difficult to determine the size of this device. Having received and inspected, there is no way that it is capable of handling a sustained 20A current. The terminal screws are small and not sufficient to engage a lug from a 12AWG cable. The overall filter design is sound, but these are not fit for purpose at the advertised rating.
