Through Hole Resistors

The KNP7WSJB-91-0R12 is a type of through hole resistor. It is used for applications requiring current and voltage protection for components and circuits. This component is also used as a load resistor for applications which require a defined load value for proper operation.

Introduction to Through Hole Resistor

Through hole Resistors are resistors with a threaded body, designed for attachment to a printed circuit board. They come in many different shapes and sizes, depending on the application. Through hole resistors are usually the best choice for applications due to their low cost and high reliability.

Types of Through-Hole Resistors

Through-hole resistors come in various types. These can include general-purpose resistors, carbon composition, metal film, and precision resistors. Each type of through-hole resistor has different characteristics and is designed for different applications. General-purpose resistors are the most commonly used type of through-hole resistor. These resistors are designed to handle a wide range of current and voltage ratings and are inexpensive compared to other types of resistors. Because of their low cost, general-purpose resistors are the most popular choice for many applications. Carbon composition resistors are usually made up of mixed carbon, clay, and other materials. These resistors are able to handle higher temperatures than general-purpose resistors, but have lower accuracy than other types. Carbon composition resistors are often used in noise-sensitive applications.Metal film resistors are made of a thin layer of metal deposited on a ceramic substrate. These resistors have better accuracy than carbon composition resistors, but still have higher temperature coefficients than precision resistors. Metal film resistors are used in applications where accuracy is a priority.Precision resistors are usually made from metal film, wirewound, or laser-trimmed resistors. These resistors have excellent temperature stability and accuracy, and are often used in high-precision applications such as measurement and control systems.
