The MFR25SDRF52-124K through hole resistor is a common resistor used in electronic circuits, made by Weidmuller. This article will discuss the application field and working principle of the MFR25SDRF52-124K.

MFR25SDRF52-124K Overview

The MFR25SDRF52-124K through hole resistor is a cement coating formed resistor with two electrically insulated rods. The resistor rods are made of metal and coated with an electrically conductive cement coating, forming a resistance body. It has an insulation class of B, a rated power of 0.25W, a tolerance of 1%, and a resistance range of 0.125 Ω to 12.4K Ω. It is a low power device, so it is suitable for low-voltage applications.

Applications

The MFR25SDRF52-124K is widely used in consumer electronics, automotive, military, industrial, and aerospace applications. It is especially suitable for controlling the current in low voltage and light load circuits. Its compact size makes it ideal for use in electronic devices with limited space. It can also be used as a voltage divider or as part of a voltage or current regulator circuit.

In automotive applications, the MFR25SDRF52-124K is used to control the current in circuits such as audio systems, climate control systems, antenna systems, and instrumentation systems. It is also used in military electronic systems such as radar systems, communication systems, and navigation systems. In addition, it is used in industrial applications such as power converters, industrial automation systems, and renewable energy systems. Finally, it is used in aerospace applications including satellites, aircraft components, and avionics.

Working Principle

The working principle of the MFR25SDRF52-124K is based on the concept of resistance. Resistance is defined as the opposition to the flow of current. The resistance of the resistor is determined by the material of the resistor rods and the size of the cement coating. The size of the coating determines the amount of current that can flow through the resistor. As the current increases, the resistance of the resistor increases, and vice versa.

When current flows through the resistor, it generates heat, which is dissipated by the cement coating. This is known as power dissipation. The power generated by the resistor depends on the amount of current flowing through it, and the resistance of the resistor. The power dissipation of the MFR25SDRF52-124K is relatively low because it has a low resistance. This makes it ideal for use in low voltage circuits.

Conclusion

The MFR25SDRF52-124K through hole resistor is a commonly used component in many electronic applications ranging from automotive to aerospace, consumer electronics to military electronics. It has a low power dissipation which makes it suitable for low voltage circuits. Its versatility makes it a popular choice for many different applications. Understanding the application field and working principle of the MFR25SDRF52-124K can help designers find the best solution for their application.
