Description: Introduction to DC power filter circuit: The circuit consists of three parts: the first part is a primary LC filter circuit, the second part is a common mode EMI filter, and the third part is a secondary LC filter circuit.<br>LC filter, commonly known as passive filter, is a traditional DC power harmonic compensation device composed of inductance and capacitance, which can filter out harmonics in the power supply once or multiple times and purify the DC power supply<br>Common mode filtering can address the problem of rapid transient group pulse interference with a repetition frequency of several thousand hertz in certain user sites, and can play a suppressive role.<br>The PCB specification is FR4 42X77X1.6MM, with the shortest design for high current circuits and short paths, which can withstand higher currents and minimize external interference.<br>The equipped inductors come in specifications: 20A.<br><br>Features: 1. Small and exquisite<br>2. Reliable Performance<br>3. Low consumption<br>4. Wide range of use<br>5. Shortest design of high current transmission lines.<br>Specifications:<br>Input: DC shall not exceed 50V (electrolytic capacitor can be replaced for lifting at higher voltage)<br>Output: DC<br>Current: 20A<br>Circuit board: double-sided FR4 fiberglass board<br>Electrolytic capacitor: 50V 470UF consumption 2 PCS<br>Thin film capacitor: 100NF 2PCS 470 PF 1PCS<br>Magnetic ring inductance: dosage 2PCS, (iron silicon aluminum is selected for 20A high current),<br>Common mode inductance; Usage: 1 PCS, (flat copper with high current of 20A)<br>Socket: 7.62 socket, 2PIN, 3PIN, 1 PCS each<br>This module is suitable for eliminating DC power sources with electromagnetic interference and can be applied to DC circuits with strong electromagnetic interference in automobiles, motorcycles, and other industries.<br>
