Through Hole Resistors (THRs) are a type of electrical component that reduces current flow in an electric circuit and provides insulation between two conductors. A typical THR is constructed from resistive elements and can be either a single pair of components or a multiple of pairs. The resistive elements, often called “leads,” usually consist of wire, subject to varying degrees of electrical insulation, and are connected at each end to a terminal or pair of terminals. The terminals are then soldered to a circuit board, which makes it possible for current flow to be regulated in a controlled manner.

The 23JR25 is a THR with an application field of high frequency use and a working principle of two-terminal shunt resistor. It was engineered for use with high frequency applications in a wide range of industrial and commercial products. This THR features a resistor in between two terminals, the other side of which is connected to a circuit board. The resistor is designed to reduce the current flow in the circuit, allowing the designer to control the flow of electrons in a manner that is most efficient for their application.

Once the 23JR25 is installed, the circuit board undergoes a process known as “doping,” in which the resistive elements are altered in order to change their electrical properties. This alters the current flow and resistance throughout the circuit board and increases the overall electrical performance of the device. For high frequency applications, the doping process can be carried out multiple times in order to achieve the desired results.

The 23JR25 also boasts an excellent resistance-to-power ratio (Rp) which is a measure of how efficient the resistor is in terms of power dissipation. It is important to have an efficient Rp in order to ensure that the resistor does not overheat, which can lead to poor performance, or even a complete system failure. The 23JR25 is specifically designed to have a high Rp, which is essential for high frequency use.

The 23JR25 also features a unique working principle, which is two-terminal shunt resistor. This type of resistor works by shunting current away from the circuit in order to reduce the power dissipated within the resistor. The resistor itself is made up of two terminals, which are connected to the circuit board and a resistor between them. When current flows through the resistor, some of it is diverted away and dissipated, effectively decreasing the overall current in the circuit.

Finally, the 23JR25 offers excellent reliability. This component is designed to withstand temperatures up to 205C, which means it is suitable for both industrial and commercial environments. In addition, the 23JR25 is RoHS-compliant, meaning it meets environmental regulations and standards. These factors make it an ideal choice for a range of different applications.

In conclusion, the 23JR25 THR is specifically designed for high frequency use and its two-terminal shunt resistor working principle ensures it can adequately reduce the current flowing in a circuit while maintaining an efficient Rp. The 23JR25 also provides excellent reliability and environmental compliance, making it a great choice for a range of applications.
