Features: Brand new and high quality The circuit is compose of three part, the first part is a first-level LC filter circuit, the second part is a common modes EMI filter, and the third part is a second-level LC filter circuit. LC filter is generally call passive filter. It is a traditional power harmonics compensation device compose of inductors and capacitors. It can filter out the harmonics in power supply single or multiple-time. Purify power supply. Common modes filtering. It can be used to suppress the problem of fast-transient group pulse interference with a repetition frequency of several kilohertz in some user sites. The shortest design of the high current circuit, can withstand high-current, and have less interference to the outside world. Suitable for eliminating power supply with electromagnetic interference, and can be used in automobiles, treadmills, generators, motorcycles, etc. Specifications: Material:ABS Current:20A Length:Approx.7.6cm/2.99inches Package Includes: 1x LC Power Filter note: 1.Please allow 1-2cm errors due to manual measurement, make sure that you do not mind before you order. 2.Due to the difference between different monitors, the picture may not reflect the actual color of the item.
