Through hole resistors are one of the most important components used in electrical systems. They are used to regulate current in circuits and also to limit the flow of current in certain applications. The RSF3JT180R is a type of through hole resistor that is commonly used in a variety of applications. In this article, we will discuss the application field and working principle of the RSF3JT180R.

The RSF3JT180R is a metal oxide film resistor with a tolerance of ±5%. It has a maximum operating temperature of 180°C and a recommended working voltage of 50V. The design also features heat dissipation and a low residual resistance value. These features make it an ideal choice for a variety of circuits and applications.

One of the most common applications of the RSF3JT180R is in power supply circuits. Its low residual resistance and heat dissipation properties make it ideal for stabilizing the output current of power supplies. It can also be used to limit the current in a circuit, by supplying a resistance that limits the amount of current drawn from the power supply. This can be useful in protecting delicate components.

The RSF3JT180R can also be used in circuits that require precision resistors. Its ±5% tolerance rating makes it ideal for circuits that need a precise current regulation, such as voltage regulators or current limiters. The low residual resistance rating also allows for a higher accuracy when measuring circuit current or voltage.

The working principle of the RSF3JT180R is fairly simple. It is a four-terminal device, with two resistors connected in series. When a voltage is applied to the terminals, electrons flow through the resistors, creating a current in the circuit. The resistors act as a voltage divider, limiting the current in the circuit and regulating the voltage.

In addition, the four terminals of the device can also be used to measure the current and voltage in the circuit. The voltage across the resistors can be determined by measuring the voltage at the common terminal between the two resistors. The current can then be determined by measuring the voltage at one of the remaining terminals.

The RSF3JT180R is a reliable and versatile through-hole resistor suitable for a variety of applications. Its four-terminal design, low residual resistance, and ±5% tolerance makes it an ideal choice for precision current and voltage control. The device is also highly heat resistant, making it suitable for use in high-temperature environments.
