CIRCUIT PROTECTION DEVICE

摘要

Provided is a circuit protection device capable of suppressing noise of at least two frequency bands. The circuit protection device according to the present invention includes a first sheet on which a pair of capacitor electrodes are formed; a second sheet which is placed on the first sheet and on which a first coil pattern is formed; a third sheet which is placed below the first sheet and on which a second coil pattern is formed; a fourth sheet which is placed on the second sheet and on which a third coil pattern is formed; a fifth sheet which is placed on the third sheet and on which a fourth coil pattern is formed; a first inductor formed by connecting the first and fourth coil patterns through holes which are formed between the sheets, between the first and fourth coil patterns and filled with a conductive material; a second inductor formed by connecting the second and third coil patterns through holes which are formed between the sheets between the second and third coil patterns and filled with a conductive material; and at least four capacitors formed between the pair of capacitor electrodes and the first and second coil patterns.
