2A 4A 10A 20A DC LC Filter EMI electroic interference Filter EMC FCC high frequency power Filtering for 12V 24V CAR-10A filter

2A 4A 10A 20A DC LC filter EMI electroic interference filter EMC FCC safety high frequency filter

DC power filter circuit introduction: The circuit is composed of three parts, the first part is a first-level LC filter circuit, the second part is a common mode EMI filter, and the third part is a second-level LC filter circuit.

LC filter is generally called paive filter. It is a traditional DC power harmonic compensation device composed of inductors and s. It can filter out the harmonics in the power supply single or multle times. Purify the DC power supply

Common mode filtering. It can be used to suppre the problem of fast transient group pulse interference with a repetition frequency of several kilohertz in some user sites. 0

The specification is FR4 42X77X1.6MM, the shortest design of the high current circuit, the short path, can withstand higher current, and have le interference to the outside world.

The inductors are available in four specifications: 2A, 4A, 10A, and 20A.

Input: DC does not exceed 50V (higher voltage can be improved by replacing electrolytic s)

Output: DC.

Current: Choose to provide 2A.4A.10A.20A on demand

Specifications of main parts:

Circuit board: double-sided FR4 fibergla board

Electrolytic : 50V 470UF consumption 2 PCS

Film s: 100NF 2PCS 470 PF 1PCS

ic ring inductance: 2PCS consumption, (20A high current select iron silicon aluminum),

Common mode inductance; 1PCS amount, (20A high current use flat copper str inductance)

Socket: 7.62 socket 2PIN 3PIN 1PCS each

This module is suitable for eliminating the use of DC power supply with electroic interference, and can be used in automobiles, motorcycles, and DC circuits with relatively strong electroic interference.
