Title:
HIGH FREQUENCY NOISE COUNTERMEASURE CIRCUIT
Document Type and Number:
Japanese Patent JP2017201761
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a high frequency noise countermeasure circuit capable of suppressing conduction and reflection of a high frequency noise by using a noise countermeasure component not requiring a complex manufacturing process.SOLUTION: A frequency noise countermeasure circuit 1 includes a wiring board 10 having wiring patterns 30, 31 and ground patterns 40, 41 with which an IC 11 is connected electrically, and a chip component 20 having a rectangular parallelepiped body 21 and a pair of external electrodes 22, 23. The body 21 is formed only of ferrite, the distance between a pair of end faces thereof (the faces provided with the external electrodes 22, 23) is set longer than the distance between a pair of principal surfaces and longer than the distance between a pair of lateral faces, one external electrode 22 is connected electrically with the wiring patterns 30, 31, and the other external electrode 23 is connected electrically with the ground patterns 40, 41.SELECTED DRAWING: Figure 1
