CHIP RESISTOR
Document Type and Number:
WIPO Patent Application WO/2021/106676
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a chip resistor that can handle high power. A chip resistor according to the present disclosure comprises an insulation substrate (11), a pair of electrodes (12), and a resistor (13). The pair of electrodes (12) are provided at the respective ends of the upper surface of the insulation substrate (11). The resistor (13) is provided on the insulation substrate (11) and is connected to the pair of electrodes (12). The insulation substrate (11) has a first region (11a) in the center thereof and a second region (11b) at each end of the first region (11a). A recess (20) is provided in the first region (11a) of the insulation substrate (11). The resistor (13) formed on the first region (11a) has a serpentine shape in plan view. At least part of the resistor (13) is embedded in the recess (20). A trimming groove (14) is provided in the resistor (13) formed on a second region (11b).
