Item Type: DC LC Filter Material: PCB Input: DC Output: DC Voltage: 50V Current: 20A Circuit Board: Double sided FR4 fiberglass board. Electrolytic Capacitor: 50V 470UF, 13mm / 0.51in diameter (approx.), 4pcs. Thin Film Capacitor: 100NF 3PCS Magnetic Ring Inductance: 2pcs, iron silicon aluminum is used for 20A high current. Common Mode Inductance: 1pc, flat copper with inductance is used for 20A high current. Socket: 7.62 socket, 2pin, 2pcs. 1、Good Structure: The circuit consists of three stages of filtering. The first part is a primary LC filtering circuit, the second part is a common mode EMI filtering, and the third part is a secondary LC filtering circuit. 2、Reliable LC Filter Module: LC filter, commonly known as passive filter, is a DC power harmonic compensation device composed of inductance and capacitance. 3、Effective Filtering: Can filter out harmonics in the power supply in a single or multiple times to improve the DC power supply. Common mode filtering can reduce rapid transient group pulse interference with a repetition frequency of several thousand Hz in certain user sites, and can play a suppressive role. 4、Wide Application: This module is suitable for reducing electromagnetic interference in DC power supplies, and can be applied to filter the output of switching power supplies, automobiles, motorcycles, and DC circuits with strong electromagnetic interference. 5、Easy to Install: Comes with a compact size and a light weight as well, the DC LC filter board is very convenient to install in minutes. 1 x DC LC Filter
