Through Hole Resistors

RWR89S1151FRB12 is a type of through hole resistors, which are the most traditional type of resistors. They have a cylindrical metal body that is made from materials like metal oxide film, ceramic-metal composites and carbon film. The body is surrounded by two wire leads, and a wide range of values of resistance can be achieved by adjusting the size of the body. The most common units are ohms.

Application Field

Through hole resistors are widely used in many types of electronics circuits. They can be found in applications such as audio amplifiers, voltage regulators, power supplies, and other circuits that require precise, precision resistance. They are also used in precision test equipment and various electronic components such as switches and timers. Their most important application in modern electronics is controlling the flow of current, particularly where tight voltage regulation is required.

Working Principle

A through hole resistor has two controlling elements. The first element is the resistive material which is placed between two terminals. As the current flows through the resistor, it experiences an electrical resistance due to the force of electrostatic attraction between the particles in the material. The second element is the electrical connection which brings the current from one terminal to the other. This connection is usually solder and its resistance is often relatively low.

The two elements together form an electrical bridge across the resistor, which is why it is often referred to as a bridge resistor. As the current passes through the resistor, some of its energy is dissipated as heat due to this electrical resistance. This is called Joule heating, and it is this phenomenon that allows us to measure the value of the resistor as a property of its construction.

Another working element of through hole resistors is the tolerances rating, which is a way of expressing how close to its ideal ratings the resistor will be in actual use. Tolerances rating will vary for different types of resistors. Through hole resistors typically have a higher tolerance rating than other types, which is why they are often specified for precision applications.

Through hole resistors are also often soldered in place during the assembly of electronic components in order to maintain the best connection possible. The use of soldering helps ensure a good electrical connection and also strengthens mechanical connections. This is critical for ensuring that the resistors are reliable and long-lasting.

Through hole resistors are ideal for applications that require precision and stability. They can be used for applications ranging from radio frequency attenuators to audio transducers and more. Their versatility makes them popular across a wide range of industries, from automotive electronics to security systems.

Through hole resistors are also relatively cost effective, making them a popular choice for many different projects. For all of these reasons, through hole resistors are one of the most widely used and important components in modern electronics.
