Abstract

The invention provides a laminated sheet type magnetic bead. The laminated sheet type magnetic bead comprises a laminated body, end electrodes and an inner electrode coil. The end electrodes are located on the two sides of the laminated body and connected with the two ends of the inner electrode coil respectively. The laminated body comprises multiple layers of base body membranes, the inner electrode coil is formed by sequentially connecting inner electrode units located between different layers of base body membranes, each inner electrode unit is provided with a leading-out end and a leading-in end, the leading-out ends and the leading-in ends of every two adjacent inner electrode units of the inner electrode coil are connected through fuse metal connecting pieces, when the temperature of the inner electrode coil is higher than that of the fusion points of the fuse metal connecting pieces, the fuse metal connecting pieces are fused, and the inner electrode coil is disconnected. The fuse metal connecting pieces are adopted for connecting every two adjacent inner electrode units, so that the laminated sheet type magnetic bead has the magnetic bead function and the fuse function at the same time.

Description

technical field [0001] The present invention relates to the technical field of electronic components, in particular to a laminated chip magnetic bead. Background technique [0002] In circuit design, the external power supply is generally provided by the system. Since the external power supply provided by the system will have a certain noise (Noisy), the noise will enter the Printed Circuit Board (PCB) and affect EMI (Electromagnetic Interference, Electromagnetic Interference). ), RF (Radio Frequency, radio frequency) test results, so it is necessary to place a magnetic bead (Bead) component at the power input end to suppress high-frequency noise and spike interference on signal lines and power lines, and play a filtering role. In addition, due to the instability of the external power supply provided by the system, such as high current and high voltage, in order to protect the components in the circuit from being burned and seriously affected when large current and high volt...
