Surface Mount Fixed Resistors

Surface Mount Fixed Resistors

Surface mount resistors, also called SMD, are the most commonly used resistors as they mitigate the transmission of the electrical voltage in circuits. A resistor controls the flow of current, like how a faucet controls the flow of water down a pipe. The resistance does not fluctuate with temperature or voltage since they operate at a set value

These resistors benefit printed circuit boards (PCBs) by reducing space. Sizes like 0201, 0402, 0603, 0805, 1206, 1210, 2020, and 2512 are typical ones. Due to their tiny size and outstanding dependability, resistors are employed in huge quantities and are the preferred option in electronic equipment. SMD resistors are used extensively in advanced technology research instruments, telecommunication equipment, automobiles (AEC Q200 certified), and medical equipment.

Types of surface mount resistors

  • Thin Film Resistors comprised a potential precision as compared to the thick film.
  • Thick Film Resistors are installed for common use because of a lower price point
  • Moulded Wirewound Resistors offer high potential power
  • Foil Resistors for ultra-high precision and ideal low-Temperature coefficient of resistance
  • Shunts (current sense) reduced ohmic values for where a current calculation is critical
  • Melf (cylindrical) provides superb pulse load capacity.

What is a surface mount fixed resistor used for?

The majority of electronic board designs employ SMD fixed resistors because of their small size. This has enabled the creation of ever-smaller PCB designs and the capacity to extract more from the board due to their compact size and the ongoing development of ever-smaller footprints. The board's component count can be reduced with the help of the resistors.

What is the difference between thin film resistors and thick film resistors?

The primary distinction is that a paste is shot onto the manufacturer's preferred substrate for thick film resistors. As the name implies, thin film resistors have an incredibly thin metal film that is typically vacuum deposited on the substrate of the manufacturer's choice.
