Positive and negative dual power supply DC LC low-pass filter electromagnetic interference to eliminate high-frequency noise of automobile engine.

Introduction of DC positive and negative dual power supply filter circuit: The circuit consists of two parts. The first part is a one-stage LC filter circuit. The second part is a two-stage LC filter circuit.

LC filter is generally called passive filter. It is a traditional DC power harmonic compensation device composed of inductors and capacitors. It can filter out harmonics in the power supply one or more times. Purify the DC power supply

The PCB specification is FR4 glass fiber double-sided 43X86X1.6MM. The high-current circuit is shortest designed. The path is short. It can withstand higher current. It has less interference to the outside world.

Inductance : 2A, 10A, 20A

Input: positive and negative dual power supply DC does not exceed 50V (higher voltage can replace the electrolytic capacitor to improve)

Output: Positive and negative dual power output

Current: 2A .10A.20A

Main parts specifications:

Circuit board: double-sided FR4 fiberglass board

Electrolytic capacitor: 50V 470UF dosage 4 PCS

Film Capacitor: 100NF 2PCS 220 PF 2PCS

Magnetic ring inductance: The dosage is 4PCS, (20A high current selects iron, silicon and aluminum),

Socket: 7.62 socket 3PIN each 2PCS

This module is suitable for eliminating the use of positive and negative dual power supply DC with electromagnetic interference. It can be used in automobiles, motorcycles, vehicle-mounted single DC to positive and negative power supplies, switching power supplies, and other DC circuits with strong electromagnetic interference.
