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

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. 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 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. 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. The equipped inductors come in specifications: 4A. Features: 1.Small and exquisite 2.Reliable Performance 3.Low consumption 4.Wide range of use 5.Shortest design of high current transmission lines Specifications: Input: DC shall not exceed 50V (electrolytic capacitor can be replaced for lifting at higher voltage) Output: DC Current: 4A Circuit board: double-sided FR4 fiberglass board Electrolytic capacitor: 50V 470UF consumption 2 PCS Thin film capacitor: 100NF 2PCS 470 PF 1PCS Magnetic ring inductance: dosage 2PCS Common mode inductance; Usage: 1 PCS Socket: 7.62 socket, 2PIN, 3PIN, 1 PCS each 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.
