Through Hole Resistors

Through hole resistors, including MFR50SFRE52-806K, are widely used in various electronic circuits, as they can be used to adjust current and voltage in the described circuit. They are significantly more robust compared to the surface mount resistors due to their enormous size and the construction of through hole resistors. The large size provides a better operating environment, which allows the component to withstand temperature extremes. The metal-film type of resistors also offers excellent stability with minimal noise and distortion.

MFR50SFRE52-806K Application Field

MFR50SFRE52-806K is an axial-leaded type Metal Film Resistor, with a tolerance of 0.1%. It has a rated power dissipation of 800mW and a dissipation factor of 4*10-5. The thermal resistance between junction and air is around 100K/W.The MFR50SFRE52-806K is most commonly used in power supplies, voltage-regulation, signal-processing systems and amplifiers, and for buffering or voltage-divider circuits. It is specially designed for high-precision analog applications where repetitive and pulsed potentiometers are replaced with fixed resistors. It can also be used in switched-mode power supplies.

Working Principle

The operation of through hole resistors is simple. When current flows through a resistor, it faces resistance which decreases the current flow. The voltage drop across the resistor is proportional to the current flow through it and is referred to as Ohm’s law. Through hole resistors are constructed by depositing tiny amounts of a metal or a metal compound onto a ceramic substrate, creating a metal film. The resistance is determined by the amount of metal deposited onto the ceramic. The metal film then rinses off the current in-situ.Through hole resistors are highly reliable due to their improved heat dissipation ability. The construction of through hole resistors allows heat to escape easily, preventing the components from burning out due to excessive heat build-up. Additionally, they can also handle heavy currents without any problems.

Conclusion

Through hole resistors are essential components for various applications and are widely used in the industry. The MFR50SFRE52-806K is an excellent example of a through hole resistor as it provides an excellent level of performance and reliability. Owing to its impressive stability and tolerance, the MFR50SFRE52-806K is the ideal choice for various analog and digital applications.
