Feature: 1. 3 Layer Filtering: The DC power filter circuit consists of three stages of filtering, the first part is the primary LC filtering circuit, the second part is the common mode EM filtering, and the third part is the secondary LC filtering circuit. 2. LC Filter: Commonly known as passive filter and a DC power harmonic compensation device composed of inductance and capacitance. It can filter out harmonics in the power supply once or multiple times, purify the DC power supply, and achieve common mode filtering. 3. Pulse Suppression: Can solve fast transient group pulse interference with a repetition frequency of several thousand hz in certain user sites, and can play a suppressive role. 4. Wide Utility: This module is suitable for filtering 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. Input and Output: Designed to have 2 input terminals and 2 output terminals, and all the terminals are dual cord 7.62 wiring terminals. Specification: Item Type: EMI Filter Material: PCB Input: DC Output: DC Socket: 7.62 Voltage: 50V Current: 20A. Package List: 1 x EMI Filter Note: Capacitor with random color.
