SMD Resistor, Surface Mount Resistor
Plenty of SMD resistors are used every day. They are square. Both ends of the resistor features a metal region, making it capable to be welded together with the PCB (printed circuit board).
RAB1 Surface Mount ResistorsSouthern Group is professional in offering RAB1 surface mount resistors for surface mounting. It is usually manufactured into square shape. Its leads or pins can be welded on the PCB board instead of passing through the PCB board.
