▎ 摘　　要

NOVELTY - The coil has an S-shaped coil whose two ends are respectively connected with two groups of a circular coil. The first group of the circular coil is connected with a third group and a fourth group of the circular coil. A circular loop is connected with an anode pin of the circular coil. A cathode pin of the circular loop is connected with the S-shaped coil. The cathode pin and the anode pin of the circular coil are arranged in parallel to form a tubular choke structure. A choke ring is connected with the circular coil and the S-shaped coil. A surface of a wire is coated with a filter layer. USE - Graphene filtering choke coil. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a graphene type filtering choke preparing method. DESCRIPTION OF DRAWING(S) - The drawing shows a front view of a graphene filtering choke coil.
