Abstract
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.
Claims3
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.
Dependencies are inferred from the claim text.
