A surface mount resistor is a tiny rectangular ceramic body with silver conductive edges on either end. Also referred to as surface mount technology, an SMD resistor offers advantages in saving space on printed circuit boards (PCBs). It features the resistance value code printed onto it, where there is space. Solder paste is printed onto the mounting pads of a PCB, and the resistors are placed automatically onto these pads by pick and place equipment. The whole board is then passed through a reflow oven which melts the solder into place, making the contacts.
A surface mount resistor provides the same functionality as the more traditional axially leaded resistors but has a lower power dissipation capacity and oftentimes a lower stray inductance and capacity. Surface-mount resistors can be thick film, which is the most commonly used, thin-film, which offers accuracy and stability, metal strip, for current sensing, or wire-wound, which is molded construction as opposed to a flat chip.
Surface-mount resistors are used in large quantities and are the preferred resistor for use in electronics equipment, because of the small size and high reliability. Surface-mount resistors are commonly used in telecommunication, automotive, and medical equipment, as well as in personal devices, displays, and advanced technology research instruments.
