Supporting input/output voltages from 0 to 50V and load currents up to 20A, it features a triple-stage LC and common mode filter circuit for superior noise suppression. Its user-friendly terminal blocks and robust build make it ideal for professionals seeking clean, stable DC power in demanding electronic applications.

## Description

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.

Review: Worked perfectly - Knowing some about electronics I knew what I needed. However was unsure what quality I would find for 10$. Funny this little thing works suprisely well. good price for what it does. Although for some reason it takes a few seconds to work (no idea why) after that it kills the dc noise. I used it to eliminate the dc from the 48v battery in our golf cart to the sound bar handing in the rear (Evolution Golf Cart). I just spliced it inline with the two dc wires and it works. Seems to be well built. Was easy to install.
Review: Works Fantastic!! High Quality!! - I purchased the 20A LC filter because the Meanwell LRS-600-15 switching power supply I just bought to power my ham rig introduced lots of noise in the receiver. The Meanwell power supply goes into pulse skip mode when the current draw is low to help with voltage regulation and also lowers power consumption. Well, this pulse skip mode introduced a lot of interference in my radio's receive. I installed this LC filter inline between the power supply and the radio, and all interference is gone!! Truly incredible!! Quality is fantastic!

## Features

- Product name: NOYITO DC LC Filter DC EMI Power Filter
- Input voltage: DC 0 - 50V.
- Output voltage: DC 0 - 50V.
- Load rated current: 2A / 4A / 10A / 20A.
- 【INPUT Port: IN+ / IN- (two-wire 7.62 terminal block input).】
- 【OUTPUT Port: OUT+ / OUT- (two-wire 7.62 terminal block output).】
- If the module is under high load and high current for a long time, the heat dissipation of the module must be strengthened. Especially for the 10A and 20A versions, when the load current exceeds 50% and above, it is necessary to strengthen the heat dissipation, such as adding cooling fans.

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.
