Through-hole resistors are passive electronic components with two terminals, the resistance element encased in a metal or plastic package, and the two terminals extending out of the package for connecting to a circuit. The through-hole resistor type MFR100FTF73-499R is a generic-style resistor that provides narrow tolerance and high power rating. It offers multiple resistance values that range from 100 Ω to 499.9 MΩ and higher.

Features

Certain features make the MFR100FTF73-499R unique:

• Narrow resistance tolerance: +/- 0.1%, +/- 0.25%, and +/- 0.5%
• Power rating: 10 to 200 W
• Temperature coefficient: 10-200 ppm/°C
• Stability: 0.05%/1000h, 0.1%/1000h, and 0.2%/1000h

MFR resistors are known for their electrical stability, power ratings, large capacitance range, and high temperature coefficient. The components are also extremely reliable, helping to improve system performance with improved thermal resistance and minimal noise.

Applications

The MFR resistors are specifically designed for industrial and military purposes. These include power supply systems, automotive applications, telecommunications, instrumentation, signal conditioning, audio equipment, and various other industry-specific applications.

The resistors are used in precision motor drives, voltage stabilizers, and high-density power equipment. The components are also ideal for use in electronic control systems, power supply systems, measuring instruments, and industrial power control circuits. Resistor value accuracy is critical in these applications, and the MFR100FTF73-499R provides this.

Working Principle

MFR resistors use a metal film as the resistive element. The metal film is laid down on an insulating substrate, then cut into the required resistance values. The film is encased in a ceramic or plastic package. The resistor is soldered into the appropriate circuit to provide the desired resistance value.

The metal film is chosen because of its excellent temperature coefficient, low noise and superior mechanical characteristics. This film also provides a lower contact resistance than the wire-wound design. Because the metal film is cut instead of wound, the tolerances can be tighter and the resistance values more accurate, compared to wire-wound resistors.

Conclusion

The MFR100FTF73-499R offers superior electrical characteristics and stability, making it ideal for industrial, military, signal, and power applications. The resistor is designed to provide superior reliability and accuracy, with excellent temperature coefficient and reduced noise. Its resistance values range from 100 Ω to 499.9 MΩ and higher, with power ratings from 10 to 200 W.
