Through Hole Resistors are electrical components that are employed in many circuits in order to resist any changes in current flow. They come in many different sizes and forms including the FCR200JR-73-75K. This particular component is a non-inductive type of through hole resistor that is designed to offer a high level of precision. Here, we will look at the application field and working principle of this specialised component.

Application Field

The FCR200JR-73-75K is ideal for applications which require a high precision, low thermal coefficient and fast response. It is also suitable for use in power supplies and motor controllers. This resistor is designed for high voltage and has a working voltage of up to 1000V. In addition, it is able to handle very high power dissipation up to 100W. It is also especially well-suited for use in temperature measurement and control circuits.

Working Principle

The FCR200JR-73-75K has a unique construction compared to other types of through hole resistors. It comprises a ceramic rod, an insulating tape, a metallic-net structure and an element wire. This wire is wound around the ceramic rod, which acts as a resistive element. The structure of the metallic-net provides mechanical and electrical support to the whole construction. Finally, the insulating tape is used to insulate the wire from the ceramic rod.

When current flows through the element wire of the FCR200JR-73-75K resistor, the ceramic rod is heated up. As the temperature increases, the resistance of the element wire also increases. This change in resistance is used to modulate the current flow. The resistor is able to maintain a constant value of resistance even when the temperature changes as its thermal coefficient is very low.

In addition, this through hole resistor also has a fast response time and provides superior accuracy. This makes it ideal for sensitive applications. The FCR200JR-73-75K has a wide range of applications and is able to offer a high level of performance in a wide variety of circuits.
