Through Hole Resistors are made up of lots of small metal discs all of the same size that are strung together on a single core. The discs create an electrical loop that generates a resistance with each link in the chain. Connecting the electrical loop to two ends of the chain allows electrical energy to flow from one end to the other through the resistive material. RSF200JB-73-18K is an example of a through hole resistor.

The RSF200JB-73-18K is an axial two-terminal leaded resistor with 18 kOhm value resistance and tolerance rating of ±5%. The J is a size code that stands for axial lead type and the number 73 represents the wirewound material.

The application of RSF200JB-73-18K includes many areas such as automotive, industrial, audio/visual, and communication systems. Automotive applications include not only the control of lighting systems, charging systems and starting systems, but also heating and air conditioning systems. RSF200JB-73-18K is particularly suitable for applications where large resistance changes occur with temperature changes, as it is made with materials that have low temperature coefficients.

In industrial settings, the RSF200JB-73-18K resistor is often used to regulate voltage in power supplies and in motor control circuits. It is also used to regulate the speed of motors, limit current, and for terminal protection. For audio/visual systems, it is used to help limit current flow in high-power audio amplifiers and audio/visual equipment. In communication systems, it plays a major role in providing constant voltage and/or current used in many circuits.

The working principle of the RSF200JB-73-18K resistor is relatively simple. Electrical current is transmitted through the wirewound resistor and produces a voltage drop due to its resistance. This voltage drop is determined by two factors, the size of the resistor and the amount of current that is passing through it. The size of the resistor determines the total resistance of it; whereas the current determines the amount of voltage drop across the resistor. When the size of the resistor and the amount of current remain constant, then a fixed amount of voltage drop is produced.

To sum up, the RSF200JB-73-18K resistor is a through hole resistor with an 18 kOhm value resistance, ±5% tolerance rating, and made of wirewound material. It is used for many applications such as automotive, industrial, audio/visual, and communication systems. The working principle of the RSF200JB-73-18K is that electrical current is transmitted through the resistor, producing a voltage drop due to its resistance. The size of the resistor and the amount of current passing through determine the amount of voltage drop produced across the resistor.
