A through-hole resistor is a two terminal passive element that comes with a long, flexible lead that can be inserted into a PCB board. The technology used to insert resistors in PCBs is of two types, i.e. axial type and radial type.
 
Through hole resistors find applications in alternative energy, consumer electronics, computers, and telecommunications. Rise in technology advancements, and increased usage of high configuration systems drives growth of the through-hole resistors market.


Through hole resistors provide high mechanical bond and are strong, as compared to resistors built with surface mount technology. This directly drives the through-hole resistor market. Through hole resistors are used in aviation and military applications, owing to their ability to withstand mechanical stress and high temperature. This is expected to be another key driver for the through hole resistor market. However, through hole technology is expensive, and it involves drilling the PCB board, which is time consuming. It also limits the availability of routing, as the leads must pass through the hole. These are some of the major disadvantages identified in the technology, which may restrain growth of the through hole resistors market.

 
Through hole technology is reliable and through-hole segments are best utilized for high quality items that require more grounded association between layers. SMT (surface mount technology) parts are secured just by solder on the surface of the board, permitting the segments to withstand more ecological anxiety. This is the reason that through-hole innovation is regularly utilized as a part of military and aviation items that may encounter extraordinary increasing velocities, impacts, and high temperatures. Through hole mounting type innovation is additionally valuable in test and prototyping applications that occasionally require manual alterations and substitutions.
