Through Hole Resistors, such as MFR25SFRF52-8R25, are commonly used components in electronics systems as they provide a precise level of resistance and adequate power dissipation in a variety of applications. Through hole resistors are generally categorized according to their size: axial (ie, with lead wires extending outward from opposite sides of a cylindrical body), radial (ie. with lead wires extending outward from the same side of a cylindrical body), and disk (ie. with lead wires extending outward from the opposite sides of a larger disk body). MFR25SFRF52-8R25 is an axial through hole resistor that is characterized by its high degree of precision, stability, and reliability. This resistor is a precision device, with tolerances of ± 0.25% and TCR (temperature coefficient of resistance) of ± 5 ppm/°C. This enables MFR25SFRF52-8R25 to accurately adjust resistance in the application, thereby providing the desired levels of current in the circuit.

MFR25SFRF52-8R25 is commonly used in high-accuracy, high-frequency applications such as digital signal processing, power controls, and military applications. The resistor can also be used in high-resistance and low-power applications, such as bias controls and filtering. Additionally, the resistor is often used in temperature-critical, pulse-sensitive applications. In such applications, the resistor offers exceptional performance as it is capable of handling extreme temperatures and can provide stable and consistent resistance levels.

The working principle of MFR25SFRF52-8R25 is based on the principle of ohmic resistance. When a current is applied to it, the resistance causes the voltage drop across the resistor to be proportional to current. The resistance of the resistor is determined not only by the number of resistive elements in the resistor, but also by the material used to create the resistive elements. MFR25SFRF52-8R25 is constructed of a metal film formed onto a ceramic substrate, which behaves as an electrical insulator. This helps in minimising the voltage drop across the resistor.

MFR25SFRF52-8R25 is constructed with a cylindrical body, in which two lead wires emerge from the oppsite sides. The resistor is usually printed with a code on the body to indicate its resistance value. This marking indicates the user which resistance he has selected, before mounting on the circuit. It is a good practice to check the code on the resistor with the value printed on the circuit board or the datasheet before using the resistor. This helps to ensure that the correct resistance value is being used in the application.

The temperature coefficient of resistance (TCR) of MFR25SFRF52-8R25 is one of its most important aspects. The fractional change in resistance due to thermal effects is designed to be very low, typically ± 5ppm per °C. This value ensures that the resistor offers stable resistance values over changing temperature conditions. This is a vital feature in temperature-sensitive applications such as in power supplies, timing circuits and precision filtering, otherwise accuracy may be compromised.

In summary, MFR25SFRF52-8R25 is a through hole resistor with a high degree of accuracy and stability. It is suitable for use in a variety of applications including digital signal processing, power controls, and military applications. The resistor has a low temperature coefficient of resistance, making it suitable for temperature-critical applications. The resistor is easily identifiable by its code, which is placed on the cylindrical body, and helps ensure that the correct resistance value is being used.
