Resistors

Resistors are the most placed part on almost any bill of materials, yet they cause a surprising share of sourcing headaches. This category covers everything from standard chip resistor surface mount parts in 0201 up to 2512, through hole resistors for axial and radial designs, resistor networks and arrays for pull-up banks, precision trimmed resistors for measurement circuits, chassis mount resistors for power dissipation, and a range of specialized types such as current sense, high voltage and anti-surge parts. Engineers use them for current limiting, voltage division, termination, feedback networks and load balancing, so the same design may need half a dozen different resistor families from different manufacturers. When buyers source resistors, the checklist is usually practical: resistance value, tolerance (1% versus 0.1% changes both price and availability), temperature coefficient, power rating, package size and AEC-Q200 grade if the board goes into automotive or industrial gear. One trade-off worth knowing: common 1% thick film chips are cheap and widely stocked, but tight tolerance thin film or foil parts often carry longer factory lead times, so spot buys from independent channels can bridge a gap when franchised stock runs dry. The other real concern is counterfeits and remarked date codes on high-demand values, which is why lot traceability and visual inspection matter even for a part that costs a fraction of a cent. Packaging preference matters too, since many contract manufacturers will only accept full tape and reel rather than cut tape.
