Through Hole Resistors

The RWR80S4R32FRBSL is a type of through hole resistor used to reduce electrical current flow, adjust signal levels, and terminate transmission lines. Through hole resistors are made of different materials such as metal film, carbon film, and wirewound. The availability of a wide range of products allows engineers to select an appropriate resistor for a particular application. The selection of the right approach depends on the required resistance, voltage, current, and power ratings, temperature coefficient, power rating, tolerance, inductance, and capacitance.

Through hole resistors are made of two contact leads that penetrate through the two holes of the resistor’s housing material. The contacts then extend beyond the resistor’s body and are Soldered directly on the Printed Circuit Board (PCB). Alternatively, the component’s contacts are held to the circuit board via a voltage-sensitive adhesive material, such as epoxy. This is due to the fact that during the soldering process, solder flux is used, which may corrode the resistor causing its malfunction and premature failure.

When selecting the right through hole resistor, it is important to consider the operating environment and set the proper heat rating. Excessive dissipation of heat may significantly reduce the resistor’s life. In addition, it is also necessary to consider the resistor’s construction environment and operating temperature. Since through hole resistors are enclosed by their casing, they are somewhat protected from any heat dissipation. However, during high temperature applications, these components may suffer from excessive thermal dissipation.

One of the primary reasons why through-hole resistors have been so popular over the years is their precision. This is due to the fact that the measurement and production of each resistor takes into account a number of factors, such as insulation resistance, power ratings, leakage inductance, dc resistance, peak breakdown voltage, surge current, temperature ratings, and temperature coefficients. These parameters help to ensure that the resistors operate within the desired parameters and do not exceed their safe operating range.

Through hole resistors are mainly used in circuit boards and other electronic devices such as power supplies, UPSs, motors, and telecommunication equipment. They are a cost-effective solution for controlling the electrical current. In some cases, they may be used as a part of a control loop in order to regulate voltage and current. Their use is not limited to applications that require precise current regulation, but can be used in both consumer and industrial products.

The working principle of a through-hole resistor is a simple one. When a current passes through the device, it is inhibited by a process known as resistance. This process of electrical resistance produces heat, which is then dissipated from the component. The amount of heat generated is proportional to the size and type of resistor used. Depending on the application, the resistor can be designed in various sizes and configurations in order to accommodate the desired parameters.

In conclusion, through hole resistors are a type of resistor that are designed to reduce current flow, adjust signal levels, and terminate transmission lines. They are often used in circuit boards and other electronic devices, such as power supplies, UPSs, motors, and telecommunication equipment. They are also well-suited for precision control applications and are available in a wide range of sizes and configurations. In addition, they are cost-effective and require minimal maintenance.
