Through Hole Resistors are one of the fundamental components of most circuit boards and PCBs. RSF3WSJT-73-120R is a type of Through Hole Resistor, which can be used in various applications and is designed with a specific operation principle. In this article, we will discuss the application field and working principle of this type of Through Hole Resistor in depth.

The RSF3WSJT-73-120R Through Hole Resistor is an axial-lead resistor with two mounting holes. It is widely used in high-precision circuits, such as temperature sensors, transducers, pressure sensors, flow control devices, etc. The RSF3WSJT-73-120R is designed with a precision tolerance of ±10%. This type of resistor is certified to UL 94V-0 standards, which is the highest level safety standard in the industry. The RSF3WSJT-73-120R is available in different packages, depending on the application, which include axial, SMD, MIL, and surface mount.

In terms of operation principle, the RSF3WSJT-73-120R functions on the same principle as all other Through Hole Resistors, regardless of type. The resistor works by limiting the amount of current through the circuit. The minimum limit of current is determined by the value of the resistance. The RSF3WSJT-73-120R features a temperature-sensitive resistor, which results in a more stable and reliable current flow. The resistance value of the resistor is determined by the length and thickness of the resistor lead and its materials. The temperature-sensitive resistor is designed with reverse temperature coefficient, so the resistance value decreases as the temperature increases.

The RSF3WSJT-73-120R Through Hole Resistor features high stability, high reliability, and low voltage coefficient. It features an operating temperature range of -55°C to +125°C and can be used in high temperature or harsh environments. The resistor also features a maximum power rating of 0.42W and is flame retardant, making it suitable for use in demanding industrial applications. The resistor is also designed to withstanding shocks and over-voltage conditions.

The RSF3WSJT-73-120R Through Hole Resistor is designed with a working voltage of 1kV and a working frequency range of 0.01 to 2 MHz. It can be used in any circuit containing low-level signals. The resistor is also designed with a self-healing property, which allows the resistor to automatically repair any damages caused by excessive current. The resistor is also designed to be reverse polarity protected, which ensures that an incorrect polarity connection won’t damage the resistor.

Overall, the RSF3WSJT-73-120R Through Hole Resistor is designed with a wide range of applications in mind. It is suitable for use in high-precision circuits, temperature sensors, transducers, pressure sensors, flow control devices, and other industrial applications that require high temperature and harsh environmental tolerance. The resistor works on the same principle as all other Through Hole Resistors, which is to limit the amount of current through the circuit by reducing the resistance value. Additionally, the resistor features a temperature-sensitive resistor design and is reverse polarity protected, which ensures that an incorrect polarity connection won’t damage the resistor.
