Through Hole Resistors (THRs) are a common type of electronic component used in circuit board assemblies. The RSF200JB-73-39K is a THR with a fixed resistance value of 200 ohms and is mainly used in industrial control and instrumentation applications. This article will discuss the application field and working principle of the RSF200JB-73-39K THR.

The RSF200JB-73-39K THR is designed to operate in a wide temperature range (from -55°C to 125°C ) and is suitable for general-purpose applications in both consumer electronics and industrial instrumentation.

The main application fields of the RSF200JB-73-39K THR can be divided into three categories: power control, signal conditioning, and temperature control. In power control, it is used in DC-DC converters, power supplies, and motor controlling circuits. In signal conditioning, it is used in audio and video circuits, communication circuitry, and operational amplifiers (Op-Amp). For temperature control, it can be found in temperature measurement and regulation systems, heaters, and other thermal management systems.

The RSF200JB-73-39K THR contains a resistive element that acts as a resistor, which changes its resistance as a function of temperature. In other words, it has a negative temperature coefficient, which means that its resistance decreases as the temperature increases. This feature increases the safety and reliability of electronic circuits, as the resistance decreases with increased temperature and prevents the component from overloading and burning out.

The working principle of the RSF200JB-73-39K THR is based on the ohmic principle. When a voltage is applied to the terminals of the THR, it creates a current that is proportional to the voltage applied across it. The current is then converted to heat energy, which is dissipated in the form of heat. The resistance of the THR is inversely proportional to the voltage applied across it, so when the voltage is increased, the resistance of the THR decreases, and vice versa.

The RSF200JB-73-39K THR is a reliable and versatile device, which is widely used in a variety of applications. It is designed to provide precise resistance values and withstand high temperatures. Due to its temperature coefficient, it is also suitable for temperature control systems, where precise resistance values are needed for precise temperature control.

In conclusion, the RSF200JB-73-39K THR is a useful and durable electronic component, and is suitable for many different applications. From power control and signal conditioning to temperature control, it provides reliable performance and precise resistance values, making it a great choice for industrial control and instrumentation.
