Through hole resistors are a popular type of resistors, used in a wide variety of applications. The FCR200JR-73-910K is one such device, which is widely used in industrial and commercial settings. This article will provide an overview of the application field and working principle of the FCR200JR-73-910K.

Introduction to the FCR200JR-73-910K

The FCR200JR-73-910K is an axial leaded through-hole resistor with a power rating of 200 mW. It is a precision resistor with a maximum temperature coefficient of ±200 ppm/°C. The resistor has a 4-digit system of marking its value, in this case 9K, which means it has a nominal resistance value of 9 kOhm. The FCR200JR-73-910K has an operating temperature range of -55 °C to +125°C, and is considered suitable for high temperature applications due to its high temperature coefficient.

Application Field of the FCR200JR-73-910K

Due to its tolerance and high temperature coefficient, the FCR200JR-73-910K is suited for industrial and commercial use. It is particularly useful in applications where precise resistance settings are required, such as in power supplies. It is also widely used in circuit protection devices, such as current limiting resistors and voltage surge protectors. It is also a popular choice for voltage dividers and voltage regulators.

Moreover, since it is an axial leaded resistor, the FCR200JR-73-910K can be easily mounted in circuit boards for a variety of applications. It is preferred in the automotive industry for its excellent tolerance and high temperature coefficient, meaning it is resistant to both shock and vibrations.

Working Principle of the FCR200JR-73-910K

The FCR200JR-73-910K works on Ohm\'s Law, which states that the current flow is inversely proportional to the voltage across the resistor. More specifically, the resistor limits the current in a circuit based on the voltage across it. It does this by creating an additional amount of resistance to the current in the circuit, meaning that the current flowing through it is reduced as it is forced to pass through the resistor.

The voltage of the resistor is determined by the amount of current passing through it, and as such, the voltage drop across the resistor can be used to regulate the current in a circuit. For example, a higher voltage drop will allow a current to flow, but a lower voltage would limit the current. This property makes the FCR200JR-73-910K an ideal choice for precision applications, such as current limiting resistors.

Conclusion

The FCR200JR-73-910K is a popular through hole resistor, with a variety of applications. Due to its precision tolerance and high temperature coefficient, it is widely used in industrial and commercial settings. Its precision also makes it a popular choice for applications that require precise regulation of current flow, such as current limiting resistors and voltage dividers. Its axial leaded design also makes it easy to mount in a circuit board for a variety of applications. Overall, it is an ideal choice for a variety of applications, due to its precise tolerance and high temperature coefficient.
