MFR1WSFRF52-2R37

Through hole resistors are one of the most common electrical components used in electronic and electrical circuits. They are used to set circuit parameters, such as voltage and current, and also provide isolation between different components in a circuit. The MFR1WSFRF52-2R37 is a surface mountable resistor that belongs to the class of through hole resistors. It is a two-terminal, symmetrical resistor with a glass-gravel filling and thermowire as its temperature setting element. It has a rated power of 0.5 W and a rated voltage of 500V.

The MFR1WSFRF52-2R37 through hole resistor is mainly used in circuit protection and current limiting applications due to its low power rating. It can be used in circuit protection applications, such as over-voltage protection, to protect sensitive components in a circuit from over-voltage spikes or surges due to power supply fault or any other fault in the circuit. Similarly, it can can be used as a current limiting component, to limit the level of current flowing through a particular section of a circuit. This can prevent other components in the circuit from getting damaged or failing due to overcurrent.

The working principle of the MFR1WSFRF52-2R37 through hole resistor is very simple. It consists of two metal plates which are separated by an insulating material like glass-gravel and thermowire. When an electrical current is passed through the two plates, the temperature of the thermowire increases, thereby increasing the resistance of the thermowire. As a result, the current level in the circuit is reduced or limited to the desired level.

The MFR1WSFRF52-2R37 through hole resistor is a very useful and versatile component which can be used in various applications to provide protection or current limiting. It is easy to install and provides good performance while consuming only a small amount of power.
