Through Hole Resistors

Through hole resistors are basic components in electronic circuits that offer resistance to the flow of current. The FMP300JR-73-130R is one such resistor, and has been designed to be mounted into a printed circuit board (PCB). The FMP300JR-73-130R is a precision potentiometer, which fine-tunes the electrical properties of a circuit to achieve the desired performance.

Application Field

The FMP300JR-73-130R is one of the most widely used through hole resistors, as it can serve many purposes. It typically finds application in high-frequency circuits, high-voltage circuits, current measurements, and precision calibrations, among others. The precision of the product is impressive, often providing an accuracy of 0.1%. Thanks to the product’s low cost, designers can often afford to use multiple FMP300JR-73-130R in a single board, thus being able to get the desired performance. With such a versatile tool on hand, circuit designers can experiment with various designs and come up with the optimized solution for each application.

Working Principle

The FMP300JR-73-130R is a single-turn resistor, which means it has only one variable (resistance) that can be adjusted. This resistor has a power rating of 0.20W and is packaged into a small cylindrical body. The terminal connections can be accessed from the top and bottom of the unit and are labeled as A, W, and B. The A and B signals are connected to the resistance element respectively, while the W terminal is connected to the shaft of the potentiometer.

When the shaft is turned, the resistance value changes, which allows for finer control of the circuit. The FMP300JR-73-130R can handle current up to 30mA, and its total resistance range is between 0.73K and 13K. The resistor is made from a reliable material, such as Nichrome, which ensures that the device maintains its accuracy over time and continues to provide reliable performance.

Another important feature of the FMP300JR-73-130R is that it has tight tolerance. The tolerance is kept at 0.5% of the maximum resistance range, meaning any changes in resistance are well within the accepted limits. This further enables the user to precisely calibrate the electric characteristics of the circuit, thus ensuring the desired performance.

Conclusion

The FMP300JR-73-130R is a versatile, through-hole resistor designed for high-frequency and high-voltage circuit design, current measurements, and precision calibrations. It is a single-turn resistor with a power rating of 0.20W, and is capable of handling current up to 30mA. It has tight tolerance of 0.5% and is made from reliable materials to ensure consistent performance.
