Through hole resistors are one of the most common electronic components that are used in circuits. The CFR50SJT-52-1K2 is a through hole resistor that is typically used in high frequency applications. This resistor is also known as a "fixed" resistor because its resistance value stays the same no matter what the electrical conditions. In this article, we will discuss the application field and working principle of the CFR50SJT-52-1K2 resistor.

Application Field for CFR50SJT-52-1K2

The CFR50SJT-52-1K2 resistor is primarily used in high frequency electronic circuits. This type of resistor is not suitable for use in low frequency circuits. The resistor has a relatively low power rating, so it should not be used in circuits that require a high amount of current. The CFR50SJT-52-1K2 is also not suitable for use in circuits involving power transistors or other components with high current rating.

The CFR50SJT-52-1K2 is typically used in circuits such as audio amplifiers, radio receivers, and other high frequency circuits. It can also be used in transducers or other circuits that require precise resistance values. The CFR50SJT-52-1K2 has a very low voltage coefficient, which makes it suitable for use in circuits that require low voltage drop across the resistor.

Working Principle of the CFR50SJT-52-1K2

The CFR50SJT-52-1K2 is a through hole resistor that uses two contacts to provide an electrical connection. The two contacts are connected to a metal plate that is the same size as the resistor. The metal plate is connected to a small ceramic or metal core. Inside the core is a resistive material (typically a metal film) that is wrapped around the core. This material provides the resistor with its resistance. When electricity passes though the resistor, the metal film absorbs some of the energy and dissipates it as heat.

The CFR50SJT-52-1K2 also has a finite amount of power cycling range, which is the amount of stress the resistor can handle before it fails. The resistor can operate in temperatures ranging from -55°C up to +220°C. Furthermore, the CFR50SJT-52-1K2 is RoHS compliant, making it suitable for use in electronic assemblies that must comply with RoHS (Restriction of Hazardous Substances) regulations.

Conclusion

The CFR50SJT-52-1K2 is a through hole resistor that is typically used in high frequency electronic circuits. It is not suitable for use in low frequency or high power circuits. However, it is appropriate for use in audio amplifiers, radio receivers, and other high frequency applications. The CFR50SJT-52-1K2 also has a relatively low voltage coefficient, making it suitable for use in low voltage drop circuits. The resistor\'s finite power cycling range and its compliance with RoHS regulations further makes it suitable for use in a variety of applications.
