Paster type magnetic bead

The utility model belongs to the technical field of electronic components, and particularly provides a patch type magnetic bead which comprises a first magnetic core, a second magnetic core and an end pole piece. The first end of the first magnetic core is provided with a groove; the first end of the second magnetic core is connected with the first end of the first magnetic core, and an air gap is formed between the second magnetic core and the groove; the end pole piece penetrates through the groove and is connected with the first magnetic core at the groove; and two ends of the end pole piece are respectively connected with the second end of the second magnetic core. According to the magnetic bead, the air gap is arranged, so that the anti-saturation capability of the magnetic bead is improved, and the rated current of the magnetic bead is improved. The end pole piece is connected with the first magnetic core at the groove, so that the shaking of the end pole piece can be reduced, and the stability of the w
