Through Hole Resistors

RWR80S1910FSS73 is a form of through hole resistor, meaning it is meant to be affixed to a printed circuit board for a portion of the circuit, and is not a standalone device. It is a standard thick film resistor, composed of a ceramic substrate with a layer of resistive material and then topped with protective layers of glass; but is tailored to fit into a leaded package format to allow it to be installed on a board.

RWR80S1910FSS73 has an operating temperature range of -55°C to + 155°C, with a power rating of 10W. It also has a resistance range of 1K to 1M Ohms with a tolerance of ±5%. The most suitable application for this component is power circuits, high current circuits, and high frequency circuits and is appropriate for use in harsh environments.

Working Principle

RWR80S1910FSS73 works on the basis of ohm’s law. The resistor provides a voltage drop between the cathode and the anode, which depends on the resistor\'s resistance value, the applied current, and the voltage of the anode. When the current flows through the resistor, the voltage drop occurs as the electrons in the current flow through the resistor’s resistive material. The size of the voltage drop is proportional to the resistance and current.

A key advantage of RWR80S1910FSS73 is its uniform temperature coefficient. Temperature coefficient is the relative resistivity to temperature, which changes as the temperature varies. This is a vital property of resistors used in power circuits because it allows the circuit to remain stable under changing temperature conditions. RWR80S1910FSS73’s low temperature coefficient allows it to provide stable performance under varying temperatures.

Applications

A major application of RWR80S1910FSS73 is as an active element in power circuits. The resistor is designed to handle high currents and provide uniform resistance, making it suitable for use in high power applications such as motors and amplifiers.

RWR80S1910FSS73’s high-temperature tolerance makes it suitable for use in automotive and aeronautical applications, where temperature swings are common. The resistor’s low temperature coefficient is particularly important in these applications, where temperature changes can cause circuit instability if not taken into account.

RWR80S1910FSS73’s high-frequency tolerance makes it suitable for use in radiofrequency circuits. The resistor’s low frequency coefficient is especially important for these applications, as changes in resistance at high frequencies can cause circuit instability.

In conclusion, RWR80S1910FSS73 is a specialized form of thick film resistor for through hole applications. While it is mainly used in high power, high frequency, and high temperature circuits, it is also suitable for use in automotive and aeronautical applications, where temperature swings and humidity can be extremes.
