Introduction to Through Hole Resistors
Through hole resistors are a type of surface mount resistors that are made with a variety of materials and sizes that are designed to resist the flow of electrical current in electronic circuits. These devices offer a wide range of resistance values for different electrical applications — from low ohms to hundreds of megaohms (MΩ).Due to their versatility, through hole resistors are often used in a broad range of electronic applications including switching circuits, timing circuits, amplifiers, voltage dividers, power supplies, and in micro-processing modules. They are also widely used for EMI/RFI suppression, noise reduction, and RF power amplifiers.RNX0252M21FKR8 application field and Working Principle
The RNX0252M21FKR8 is a through hole resistor manufactured by Rohm Semiconductor. This resistor is made from metal oxide film material and is capable of withstanding high temperatures up to 180°C. It has a voltage rating of 2.5V, a current rating of 250mA, and a resistance range of 2.2Ω to 5MΩ. Additionally, it is RoHS compliant and UL recognized. The RNX0252M21FKR8 is mostly used in switching circuits, amplifiers, voltage dividers, and in other various electronic applications. Its low voltage rating and high resistance ratings make it a suitable choice for these applications.The working principle of the RNX0252M21FKR8 is simple. When electricity flows through this resistor, it resists the current flow to a certain degree. This resistance is represented by its ohmic value, which is a measurement of the resistance it provides to the flow of current. The higher the ohmic value, the more resistant it is to the flow of current.The RNX0252M21FKR8 metal oxide film resistor is designed to operate in both high and low temperatures, and can handle large surges in electrical current. This makes it an ideal choice for applications where temperature and current stability is critical.Advantages of Through Hole Resistors
Through hole resistors offer many advantages over traditional leaded resistors. First of all, they are much smaller and lighter in weight, making them much easier to transport and install than their counterparts.Through hole resistors also have much better performance than traditional leaded resistors. They offer greater accuracy, higher power ratings, and faster response times due to their thinner layers and smaller design. Furthermore, through hole resistors have increased reliability which is critical for any electronic device. This is achieved through their stable operating temperature range and improved heat dissipation.Conclusion
The RNX0252M21FKR8 through hole resistor is a perfect choice for a variety of applications due to its high temperature and power rating, and RoHS and UL compliance. It offers superior performance and reliability over traditional leaded resistors, making it an ideal choice for any electronic device.
