Through Hole Resistors are electronic devices which are used to regulate currents and voltages within electronic systems. In its most basic form, a resistor is a straight line of conducting material. In this article, we will discuss the application field and working principle of RSF3WSJR-73-51K, a special type of through-hole resistor.

RSF3WSJR-73-51K is a multi-turn trimmer resistor primarily used in measuring and controlling equipment. It is composed of a sealed cermet body and rotating contact adjustable mechanism. It is equipped with five turns, allowing for finer adjustment and a maximum resistance of 73 ohms. The component has a high power rating of 51K and an operating temperature range of -40°C to +105°C. RSF3WSJR-73-51K is widely used in audio-visual components, HVAC systems, computer systems, communications equipment, instrumentation, and automotive applications.

The working principle of the RSF3WSJR-73-51K is relatively simple. It consists of a carbon composition or wire wound rotor, which can move in a continuous position between actuating terminal pairs to adjust the resistance of the resistor. The resistance of the resistor is adjusted by rotating a center shaft to bring the contact points closer or further apart, thus increasing or decreasing the total resistance of the resistor. By adjusting the resistance of the resistor, it is possible to control the current and voltage in the system.
