Through Hole Resistors

Through hole resistors are a common component in the field of electronics, and they are used to create resistance in electrical circuits. The OJ5645E-R52 is one such through hole resistor, and it is mainly used for controlling and distributing power in applications such as power supply modules.

Basic Working Principle

The working principle behind a through hole resistor is quite simple. It consists of two metal terminals called "leads", which are connected to an insulating body. The leads are stressed against the insulating material so that resistance is generated between them. The greater the stress, the higher the resistance. This resistance is useful in controlling the amount of voltage or current in a circuit, and it is typically measured in ohms.
