<p>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.</p> <p>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</p> <p>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.</p> <p>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.</p> <p>The equipped inductors come in specifications: 20A.</p> <p>Features: 1. Small and exquisite</p> <p>2. Reliable Performance</p> <p>3. Low consumption</p> <p>4. Wide range of use</p> <p>5. Shortest design of high current transmission lines.</p> <p>Specifications: </p> <p>Input: DC shall not exceed 50V (electrolytic capacitor can be replaced for lifting at higher voltage)</p> <p>Output: DC</p> <p>Current: 20A</p> <p>Circuit board: double-sided FR4 fiberglass board</p> <p>Electrolytic capacitor: 50V 470UF consumption 2 PCS</p> <p>Thin film capacitor: 100NF 2PCS 470 PF 1PCS</p> <p>Magnetic ring inductance: dosage 2PCS, (iron silicon aluminum is for 20A high current), </p> <p>Common mode inductance; Usage: 1 PCS, (flat copper with high current of 20A)</p> <p>Socket: 7.62 socket, 2PIN, 3PIN, 1 PCS each</p> <p>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.note: Different batches, the appearance\/color of the electronic component on the product may be different, but the function is the same, it does not affect the use</p> <p>Material: PCB+electronic components</p> <p>colour: Yellow</p> <p>Package Contents: </p> <p>1 x Filter</p> <p>Only the above package content, other products are not included.</p> <p>Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
