Through Hole Resistors

Through hole resistors, also known as through-mount resistors, are designed to be mounted into a printed circuit board (PCB) via a hole that passes all the way through the board. These resistors typically feature an axial-leaded design with two leads on either end, a cylindrical body, and a resistor element that sits between the leads. As a result, these resistors can be sandwiched between the board and the component directly above it, creating a reliable and low-cost connection.
CMF55301K00FHEB is one of the widely used through hole resistors today. It is a grade B resistor with a rated power of 1/4th watt and a tolerance of 5%. It has a high dielectric strength at high voltage section so it cannot withstand high voltage correctly, and it uses a flame retardant material to reduce the risk of fire.
The application field of through hole resistors is varied, but it is most commonly used in situations where a component needs to be quickly connected to a circuit board without requiring a soldering iron. This makes it ideal for applications such as prototyping and experimental work where components may need to be quickly added to a board without having to solder them on. Additionally, through hole resistors can be used in situations where connector space is limited, as the leads can be squeezed into tight holes.
The working principle of through hole resistors involves the passage of an electric current through the resistor\'s element, which is typically made from a non-conductive material such as silicon carbide or nitride. This material is designed to resist the current, thereby creating resistance. As a result, the current is forced to flow through the element, and as it passes through, it is subjected to the material\'s resistance. This limits the amount of current that flows through the element, thus reducing the voltage and current that reach the connected components.
Through hole resistors can be used in a variety of applications, including amplifiers, audio systems, power supplies, and many more. As such, setting up a proper connection between a board and the component that needs to be connected is essential to ensure the correct power levels, signal strengths, and component protection. By using through hole resistors in conjunction with a variety of different components, these power levels, signal strengths, and component protections can be properly managed, allowing for easier experimentation and design work.
