Publication number: 20240029925Abstract: A resistor includes a first insulator, a resistive body, a second insulator, a pair of electrodes, and a covering body. The first insulator has a first obverse surface facing in a thickness direction thereof. The resistive body is provided on the first obverse surface. The second insulator covers the resistive body. The pair of electrodes are electrically connected to the resistive body at both sides in a first direction perpendicular to the thickness direction. The covering body is formed on at least one of the first insulator and the second insulator. The covering body has electrical conductivity. The first layer is in contact with at least one of the first insulator and the second insulator.Type: ApplicationFiled: October 6, 2023Publication date: January 25, 2024Applicant: ROHM CO., LTD.Inventor: Kosaku TANAKA

Publication number: 20230343492Abstract: A chip resistor includes a resistive element, a first conductive underlying layer, a second conductive underlying layer, a first electrode, and a second electrode. The first electrode includes a first electrode layer. The second electrode includes a second electrode layer. A first electrical resistivity of the first conductive underlying layer is higher than a second electrical resistivity of the first electrode layer and higher than a third electrical resistivity of the resistive element. A fourth electrical resistivity of the second conductive underlying layer is higher than a fifth electrical resistivity of the second electrode layer and higher than the third electrical resistivity of the resistive element.Type: ApplicationFiled: September 22, 2021Publication date: October 26, 2023Inventor: Kosaku TANAKA
