MFR2WSFTF52-43K2

Through Hole Resistors

Through hole resistors are basic components commonly used on electronic circuit boards due to their low cost, wide availability, and inherent stability. One particular type of through hole resistor is the MFR2WSFTF52-43K2. This resistor is used in many applications and has a working principle that are important to understand when incorporating the component in a design.

Application

The MFR2WSFTF52-43K2 is a non-polarized axial leaded resistor. This means that current can travel in either direction through the resistor and the direction of the current will not affect the performance of the resistor. The MFR2WSFTF52-43K2 has an energy dissipation range of ‘normal’ power. This means that the resistor is generally used in circuits that require low power. The MFR2WSFTF52-43K2 has a power rating of 1/4 Watt (250 mW) and a resistance range of 6 – 100K Ohms.

Due to its small size, the MFR2WSFTF52-43K2t is often used in printed circuit board designs where space is at a premium. It is also used in applications where small signal and power requirements need to be kept low due to close proximity of components. Examples of these applications include power supplies, medical devices, automotive systems, audio receivers, and communication equipment.

Working Principle

The MFR2WSFTF52-43K2 works through the use of a thin film and thermistor on the resistor. When this resistor is heated, the thermistor will experience a decrease in its resistance. This decrease in resistance will cause the voltage drop in the circuit to decrease as well. At the same time, the thin film will increase in resistance which causes the current in the circuit to decrease. The combination of these two effects results in the circuit responding differently to different temperatures.

The MFR2WSFTF52-43K2 can also be used to control the current flow within a circuit. This is done by using the resistor in series with the desired component. By varying the resistance value, the current in the desired component can be adjusted to maintain the optimum performance of the component. For example, a resistor in the range of 6-10K Ohms can be used to limit the current in a transistor.

Conclusion

The MFR2WSFTF52-43K2 is a type of through hole resistor that is commonly used on circuit boards. This resistor is designed with a power rating of 1/4 Watt (250 mW) and a resistance range of 6 – 100K Ohms. Due to its small size, it is often used in board designs where space is at a premium. The working principle of the MFR2WSFTF52-43K2 is based on a thin film heat sensor and thermistor that changes resistance in the presence of different temperatures. Lastly, it can also be used to control the current flow within a circuit by changing its resistance value.
