Chip resistors are essential passive components in electronic circuits, widely used in automation, industrial control, and MRO applications. These surface-mount devices (SMD) provide precise resistance values to regulate current flow, divide voltages, and terminate signals. Common types include thick film, thin film, metal film, and metal strip resistors, with variations like precision, high-power, or high-voltage models. Key specifications include resistance range (milliohms to megaohms), tolerance (0.1% to 5%), power rating (1/16W to 2W), and temperature coefficients. Chip resistors enable miniaturization in PCBs for automation equipment, motor drives, sensors, and power supplies. Typical products in this category include 0402/0603/0805 size resistors, current sense resistors, fusible resistors, and resistor networks for voltage division.
