Through Hole Resistors

A resistor is a two-terminal electronic component that creates a resistance between its two terminals. Resistance is usually expressed in Ohms and is an important fundamental component in an electrical network. The two main types of resistors are surface mount resistors and through-hole resistors.

Through-hole resistors are the traditional resistors which are mounted with leads onto printed circuit boards (PCBs). There are two main categories of through-hole resistors, NTC or negative temperature coefficient and PTC or positive temperature coefficient. In this article, we will focus on the through-hole resistor known as the OK2255E-R52.
