4A DC LC Filter FCC Car Audio High Frequency Filtering Low Pass Passive EMI Electromagnetic Interference FilterA

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: 4A.<br> Features:<br> 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: 4A<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<br> Common mode inductance; Usage: 1 PCS<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> Material: PCB+electronic components<br> colour: yellow<br> Package Contents:<br> 1 x Filter<br> Only the above package content, other products are not included.<br> Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
