Through Hole Resistors are one of the most fundamental components used in the vast majority of electrical and electronic circuits. The CPW05R2500JB31 is a type of through hole resistor that provides advantages such as a large power rating, low thermal coefficient, and wide operating temperature range, which make it an ideal choice for many applications. This article focuses on the application field and working principle of this specific component.

Application Field

The CPW05R2500JB31 is a through hole power resistor offering a maximum power rating of 5 Watts. This power rating is attainable in a wide range of environmental conditions, including temperatures of -55°C to +175°C. This wide operating temperature range is achieved through the use of a ceramic-metal composite construction and a high-temperature brazing technique to ensure thermal reliability. This makes the CPW05R2500JB31 well-suited for a variety of power dissipating and overload-protection applications. It is particularly useful for any application in which a larger power rating is required, as the CPW05R2500JB31 has more than twice the power rating of standard power resistors. Additionally, its high thermal coefficient of resistance (TCR) ensures better thermal stability over time and temperature.

Other advantages of the CPW05R2500JB31 make it suitable for many types of through hole resistor applications, such as current sensing, temperature compensation, and signal conditioning. It is also well-suited for power switching circuits, rectification circuits, and overload protection in AC/DC converters. For even greater power dissipation and overload protection, the CPW05R2500JB31 can be combined with heat sinks to disperse heat away from its construction. Such an application makes it ideal for applications running longer time cycles, or in any application requiring higher power ratings.

Working Principle

The CPW05R2500JB31 is a carbon-composite power resistor that is constructed of several layers of carbon cloth and/or carbon rods sandwiched between two pieces of metallic electrodes. This creates a three-layer resistor which can then be precisely laser cut to create the desired resistance value. The laser cutting process also generates small openings in the resistor which allow for the insertion of conductive material or pins, which are typically gold-plated copper. This process and precision laser cutting of the resistance tracks ensures that the CPW05R2500JB31 resistor will perform with extremely stable resistance values, and will provide reliable performance for its rated power over time.

The CPW05R2500JB31 is used in circuits and applications which require stable, reliable resistors that can dissipate higher voltages and power. By utilizing a carbon-composite construction and precision laser cutting for resistance tracks, the CPW05R2500JB31 is able to provide a high quality and constantly stable resistor for many applications. These aspects of the CPW05R2500JB31 make it an ideal choice for any type of through hole resistor application, with a variety of power ratings and excellent thermal stability.
