Features: The circuit consists 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 a passive filter. It is a traditional power harmonics compensation device composed of inductors and capacitors. It can filter out harmonics in power supply single or multiple times and purify the power supply Common mode filtering can be used to suppress the problem of fast-transient burst pulse interference with a repetition frequency of several kilohertz in some user locations Shortest design of the high current circuit, capable of withstanding high current and generating less interference to the outside environment Suitable for eliminating electromagnetic interference in power supplies and can be used in automobiles, treadmills, generators, motorcycles, etc Specifications: Material: ABS Current: 20A Length: Approx. 7.6cm / 2.99 inches Note: 1.
