Through Hole Resistors

Through hole resistors were initially developed to overcome the limitations of surface mount resistors that had been developed in the early 1980s. Through hole resistors are larger than surface mount resistors with a through-hole, or lead, that passes through the board and into fixtures and components on the other side. This allows the resistor to be securely mounted in position without the risk of becoming loose or coming apart.

The MRS25000C3923FRP00 is an example of a through hole resistor. This type of resistor is a medium power, non-inductive, and wire-wound design. It features an outside diameter of 0.25 inches and body length of 0.39 inches. It has a maximum power rating of 10 watts and a resistance range of 0.19 to 0.99 ohm. It is designed for medium frequency power applications and is ideal for operation at temperatures up to 150°C.

Application Field of MRS25000C3923FRP00

The MRS25000C3923FRP00 is particularly well suited for use in applications involving weighted automatic system processes, switching system controls, power plant control systems, aerospace systems, and telecommunications networks. It is also suitable for current sensing, AC to DC converters, switch mode power supplies, and current limiting in high power systems.

It provides a high degree of heat dissipation due to its non-inductive construction and improved workmanship. This makes it an ideal choice for systems that require stable input and output characteristics in the face of changing environments. Additionally, its superior noise and vibration immunity make it an optimal choice for precision applications.

Working Principle of MRS25000C3923FRP00

The MRS25000C3923FRP00 resists electric current by converting electrical energy into thermal energy. This is done by changing the resistance of the resistor in response to changes in current. As current passes through the resistor, a portion of the electric energy is converted into heat and is dissipated as heat away from the resistor. This heat is usually vented away from the device and into the environment.

The resistor also features a precise design that allows for accuracy and repeatability. Its feature of a single turn, non-inductive construction ensures a consistent and controlled operation. Furthermore, its wire-wound construction allows for maximum power dissipation while its molded finish ensures strong mechanical construction.

The MRS25000C3923FRP00 is also designed to provide superior durability and long-term performance. It is designed for temperatures up to 150°C, making it suitable for a wide range of applications. Additionally, its platinum-plated elements add corrosion and ultraviolet resistance, and its solderable construction meets the requirements of the RoHS and other environmental directives.

Conclusion

The MRS25000C3923FRP00 is a superior example of a through-hole resistor. Its non-inductive design, excellent thermal performance, and precise construction make it ideal for medium power applications. Additionally, its platinum plated elements and UV resistant finish ensures superior durability and long-term performance.
