RSF200JB-73-9K1

Through Hole Resistorsare commonly used components that are often seen in electrical circuits. They provide precise voltage and current levels for certain electrical loads. The RSF200JB-73-9K1 is one such through hole resistor. This article will discuss the application field and working principles of the RSF200JB-73-9K1.

The RSF200JB-73-9K1 through hole resistor is a standard chip resistor with a resistance value of 200 KΩ. This type of resistor typically comes in a four banded axial case with a body length of 7.3 mm. It is a commercial grade resistor that is used primarily in basic electrical circuits and signal switching with lighting systems.

The RSF200JB-73-9K1 has three primary application fields. First, it is used in the filtering of AC power in electronic equipment. Second, it is used as a current-limiting resistor for alternating current circuits. Third, it is used to control overtemperature in electronic circuits and is also used in line matching and over-voltage protection.

The RSF200JB-73-9K1 is a physical resistor made of metal, typically a alloy of nickel-iron. The key to its working principle is the fact that when current passes through it, it generates heat. This heat causes the resistor to expand and increase in resistance by a small amount. This is known as the “self-heating effect” and is part of its function.

When used as a current-limiting resistor, the RSF200JB-73-9K1 begins to heat up when its resistance is exceeded. This is because more current is then passing through the resistor, and, as such, it increases in temperature. As the resistor heats up, its resistance increases, causing the overall current to decrease. This is known as a “current limiting” function. The thermal overload circuitry within the resistor then responds to the increased temperature, switching off the current.

When used as a line matching resistor, the RSF200JB-73-9K1 acts as a voltage-dropping resistor. This is because it has a higher resistance rating than other resistors in the circuit. As a result, it will draw less current overall, thus dropping the voltage and balancing the overall circuit.

Finally, when used as an over-voltage protection device, the RSF200JB-73-9K1 acts as a safety resistor. This is due to its ability to prevent excessive amounts of current passing through the circuit. As the current passes through the resistor, it generates heat, which causes the resistor to expand and increase in resistance. This, in turn, reduces the amount of current passing through the circuit, thus protecting the components.

The RSF200JB-73-9K1 through hole resistor is a versatile device that can be used in many different applications. Its ability to generate heat and to control current makes it ideal for signal switching with lighting systems, as well as current-limiting and over-voltage protection. The RSF200JB-73-9K1 is a commercial-grade resistor that provides precise voltage and current for any electrical load.
