Chip resistors have the characteristics of limiting DC or AC. Such characteristics are used to drop the voltage or maintain the current at a certain level inside an electronic circuit. Resistance basically follows the Ohm’s law. Materials of high and low electrical conductivities are used together to realize the required resistance value. The main resistance element materials of chip-type resistors are SiO2, RuO2, and CuNi, making it possible to make products that have high resistance, low resistance, ultralow resistance, antisulfur, and array resistance properties.

Current Sensing Resistor

Chip resistors are manufactured in a rectangular parallelepiped shape to ensure that they can be surface-mounted. These resistors are all-around passive components that are most widely used in electronic circuits together with capacitors. They regulate current and drop voltage in circuits. New products are continuously developed as sets are made smaller in size and have advanced functions.
