Title:
NOISE PREVENTION RESISTOR AND MANUFACTURING METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/085339
Kind Code:
A1
Abstract:
In this noise prevention resistor 10, an electromagnetic shield member 8a, which covers a part of the outer peripheral surface of a resistance element 2 without interruption around the axis of the resistance element 2, is disposed at a position on the outer peripheral surface of the resistance element 2 where the resonance frequency of a resonance circuit is different. Thus, the electromagnetic shield member 8a magnetically separates the resonance circuit of a resistor. As a result, since a plurality of resonance equivalent circuits are provided in a single resistor element and the resonance peak of the resistor has a width, noise can be suppressed in a wider band than before while maintaining the length dimension and the like.
