Product description
*Items with the shortest distance to high current lines
Introduction to DC power supply filter circuit: This circuit consists of three parts. The first part is the primary LC filter circuit, the second part is the common mode for EMI filter, and the third part is the secondary LC filter circuit.
LC filter, generally called a passive filter, is a traditional DC power supply harmonic compensation device composed of inductors and capacitors. It can filter out1or more harmonics in the power supply and purify the DC power supply.
Common mode filtering can solve the problem of fast transient group pulse interference with a repetition frequency of several thousand Hz at some user locations, and can also suppress it.
PCB specification is FR4 42X77X1.6MM, the shortest high-current circuit design, short path, can withstand greater current, and less interference to the outside world.
The corresponding inductors are 10A, 20A,
Input: DC does not exceed 50V(higher voltage can be increased by replacing electrolytic capacitors)
Current: 10A.20A supplied for on demand.
Main parts specifications:
Circuit board: double-sided FR4 fiberglass board
Electrolytic capacitor: 50V 470UF usage 2PCS
Film capacitor: 100NF 2PCS 470 PF 1PCS
Magnetic ring inductor: 2PCS dosage,(20A high current single),
Common mode inductor; dosage 1PCS,(20A high current single copper strip flat inductor)
Socket: 7.62 socket 2PIN 3PIN each 1PCS
This module is suitable for DC power supplies that eliminate electromagnetic interference, and can be used in automobiles, motorcycles, and DC circuits with relatively strong electromagnetic interference.
