• Surface-Mount Resistors also called chip resistors
• Much smaller than conventional resistors with axial leads.
• Their end electrodes are soldered directly to a circuit board.
• Power dissipation rating is usually half ¼ to ¼ W
• SMT resistors are temperature-stable and rugged
• Surface mount resistors have a numerical code indicating a value
• All resistors have a tolerance value
