Through-hole resistors are a type of resistor that comes with two lead terminals that pass through a hole on circuit boards or a chassis. The prefix PNP7WVJT-91-82R specifies a through-hole resistor device, and this article will discuss its application and working principles.

Types of Through-Hole Resistors

The most common types of resistors used in through-hole applications are carbon composition, metal oxide film, wirewound, and metal film. Carbon composition, also known as carbon film, is the oldest form of through-hole resistors and consists of strands of carbon that are contained in a ceramic material. This type of resistor is often used in power supplies and other power applications. Metal oxide film resistors are made using a layer of metal film, which is then coated with a layer of metal-oxide. This type of resistor is very stable and has extremely low noise. Wirewound resistors are constructed by winding a metal wire around a core material, and are used in power applications and precision circuits due to their accuracy and low noise. Lastly, metal film resistors, also known as film resistors, are constructed by depositing a layer of metal onto a ceramic base material. This type of resistor is used for high accuracy measurements and current regulation.

Working Principle

A through-hole resistor is an electrical component that contains a metallic film over a substrate material. This metallic film, when placed between two electrical terminals, provides resistance. When current passes through the device, some of the energy is converted into heat, which is dissipated by the device. The resistance of a through-hole resistor can be adjusted by changing the size of the metallic film or by changing the material used in the substrate.

In the case of the PNP7WVJT-91-82R, a precision film resistor is used to control the current. The metallic film is made from a material that exhibits a low temperature coefficient, which means that the resistance remains consistent over a wide temperature range. This type of resistor can also provide a high degree of accuracy and stability.

When designing with the PNP7WVJT-91-82R through-hole resistor, it is important to take into consideration the environment in which the device will be operating. Since the resistor operates at high temperatures, it should be mounted in an area that is well-ventilated to ensure proper cooling.
