Through-hole technology based resistors

Through-hole technology is a way to mount electronic components to printed circuit boards (PCB).

It involves the use of leads on the components that are inserted into holes drilled in the PCBs and soldered to pads on the opposite side either by manual assembly (handiwork) or by the use of automated insertion mount machines.

Many parts made for through hole mounting are larger than those for surface-mount technology.

  • Resistors (1)

    Through-hole (leaded) resistors

  • MOS6581 chtaube061229

    Through-hole devices mounted on the circuit board of a mid-1980s home computer. Axial-lead devices are at upper left, while blue radial-lead capacitors are at upper right

  • Capacitors electrolytic

    Axial- (top) and radial- (bottom) leaded electrolytic capacitors

  • Integrated Circuit

    Components like integrated circuits can have upwards of dozens of leads, or pins

  • Box of 02in pcb bits

    A box of drill bits used for making holes in printed circuit boards. While tungsten-carbide bits are very hard, they eventually wear out or break. Making holes is a considerable part of the cost of a through-hole printed circuit board.
