Abstract
The intensity of unintended electromagnetic radiation caused by connector contact failure mainly depends on the increased inductance at the contact failure portion. Self-inductance caused from increased current path at the contact boundary surface has been considered the factor of increased inductance. However, investigation of mutual inductance due to the interaction among contact points is insufficient. In this paper, by using contact failure model, calculated current path length and increased inductance including mutual inductance are compared. The result shows that the more current path lengthens, the more mutual inductance increases. Mutual inductance should be considered when estimating contact failure.
