PT-0008 DC power filter circuit introduction: The circuit consists of three-stage filtering, the first part is - - stage LC filter circuit, the second part is common mode filtering, and the third part is 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 harmonics in the power supply one or more times. Purify the DC power supply and common mode filtering, which can suppress the problem of fast ient group pulse interference with a repetition frequency of several kilohertz in some user sites.<br><br>Input: DC. Output: DC. Voltage: 50V (higher voltage can replace the electrolytic capacitor to improve) Current: 20A Main Parts Specifications: Circuit board: Double-sided FR4 fiberglass board Electrolytic capacitor: 50V 470UF diameter 13MM dosage 4 PCS Film Capacitor: 100NF 3PCS Magnetic ring inductance: the amount of 2PCS, (20A high current use FeSiAl), Common mode inductance; consumption 1PCS, (20A large current choose flat copper tape inductance) Socket: 7.62 socket 2PIN 2PCS This module is suitable for eliminating the use of DC power supply with electromagnetic interference. It can be applied to filter after switching power supply output, automobiles, motorcycles, and DC with strong electromagnetic interference. The factory batches are different, and some appearances may be different, which has no effect on the product Colour:Photo Color Material:ABS<br><br>Package Contents: 1 x Low pass filter<br><br>Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
