Abstract
Official abstract text for this publication.
Provided is a current detection resistor that is small and that inhibits influence of the skin effect due to high frequency current. The resistor includes a resistor body ( 11 ) and at least a pair of electrodes ( 12 ), wherein the resistor body ( 11 ) is configured in a pillar-shape having diameter of 4 mm or less disposed between the electrodes. Each of the electrodes ( 12 ) is made to be longer in the direction in which the electrodes are placed and longer than twice the distance between the electrodes, which sandwich the resistor body. Further, each of electrodes ( 12 ) is square pillar-shaped, and the resistor body is fixed to roughly to center of the electrode in cross-section.
First claim
Opening claim text (preview).
The invention claimed is: 1. A current detection resistor, comprising a resistor body; and at least a pair of electrodes, wherein the resistor body is configured in a pillar-shape having a diameter of 4 mm or less disposed between the electrodes, wherein the resistor has a step difference at a joint portion between the resistor body and the electrode, and wherein a length of the resistor body is smaller than 1.5 times the diameter of the resistor body. 2. The current detection resistor according to claim 1 , wherein each of the electrodes is made to be longer in direction in which the electrodes are placed, and longer than twice the distance between the electrodes, which sandwich the resistor body. 3. The current detection resistor according to claim 1 , wherein each of the electrodes is square pillar-shaped, and the resistor body is fixed to roughly to center of the electrode in cross-section.
