Introduction to Through Hole Resistors

Resistors are basic electronic components that are found in almost all electronic circuits. Through hole resistors (also known as THRs) have remained popular since their introduction in the early 20th century. They are usually the most reliable and cost-effective option for most applications, even with the advent of modern surface-mount versions.

THRs are two-terminal passive components that contain a resistive material between them. Generally made from ceramics or graphite, THRs are wound and layered around a shell in order to create their desired resistance value. They come in a wide variety of shapes and sizes, making them suitable for many different applications. Additionally, they possess the unique ability to be easily upgraded or replaced, which is one of the main reasons why they remain popular today.

This model can withstand higher currents than other resistors and is suitable for both AC and DC applications.

The PNP400JR-73-18R has the following dimensions: 7.3mm (width) x 18mm (length). It is made up of six coats of resistive material and is wrapped in a robust ceramic shell. This model can handle up to 334W of heat for up to 5 seconds without breaking.

PNP400JR-73-18R: Application Field and Working Principle

Through hole resistors like the PNP400JR-73-18R can be used in a wide variety of applications and are often found in industrial, automotive, and consumer electronics. They are most commonly used to reduce current flow, limit voltage, and hold circuits steady. Additionally, these resistors can be used to convert alternating to direct current, generate heat, and increase current flow.

The working principle of the PNP400JR-73-18R is quite simple. When a voltage is applied to it, the resistive material inside it constricts the flow of electric current. The amount of resistance provided by the PNP400JR-73-18R can be adjusted depending on the type and number of layers of resistive material around the ceramic shell. This allows it to be tailored to the specific needs of the user.
