Through Hole Resistors

Through hole resistors are passive components used to control current and voltage levels in electrical circuits. They are widely used to reduce the flow of current in a circuit, to divide the voltage across a circuit, and to control the power dissipation in a circuit. A resistor can be either of two types, namely the discrete or packaged type.

A resistor of the discrete type is made up of one or more ceramic or metal rods. The most common form of the discrete resistor is the wirewound type, which is a long wire wound around a ceramic or metal core. It is often used in order to increase the power rating of a resistor and to limit the temperature rise within a resistor. The other type of resistor – the package type – is typically used in surface mount applications and consists of a plastic or ceramic material with an electrically conductive internal layer.

The RSF5WSJB-91-2R is an example of a through hole type of resistor. It is designed for use in electronic circuits where a large resistance value is not required, and temperatures up to 125°C are not anticipated. It consists of a ceramic body with two contacts for soldering, with a wirewound resistance element mounted inside. The solder connections are generally connected to copper or tin plated components in order to increase the temperature resistance and reduce the risk of corrosion.

The working principle of the RSF5WSJB-91-2R is fairly straightforward. It is a voltage-controlled device, meaning that its resistance value will increase when the voltage across the resistor increases. This effect is due to the behavior of the wirewound resistive element, which has a greater resistance at higher voltages. The resistance the device exhibits is also dependent on the temperature of the surrounding environment; as the temperature increases, the resistance value of the resistor will decrease.

Due to its low resistance value, the RSF5WSJB-91-2R is ideally suited for applications such as voltage divider circuits and low-level current sensing circuits. In voltage divider circuits, the RSF5WSJB-91-2R can be used to accurately divide the voltage across a circuit, while in current sensing circuits it can be used to measure the current flowing through a circuit.

The RSF5WSJB-91-2R is also used in various applications such as audio circuits, motor control circuits and power supply circuits. In audio circuits, the RSF5WSJB-91-2R is used to adjust the gain of an amplifier, while in motor control circuits it can be used to set the speed of a motor. Finally, in power supply circuits the RSF5WSJB-91-2R can be used to reduce voltage levels, thus providing a higher level of safety for sensitive circuits.

In summary, the RSF5WSJB-91-2R is a through hole resistor designed for use in low-power electronic circuits. It is a voltage controlled device, and its resistance value will increase when the voltage applied across it increases. It is used in many different applications, including audio circuits, motor control circuits and power supply circuits, where it can provide accurate voltage and current control.
