Through hole resistors are an important type of electronic components commonly used in electrical circuits for applications such as slowing down or controlling current, providing signal measurements or voltage references, and providing thermal protection and over-current protection. In this article, we will discuss the UB5C-240RF8 application field and working principle as one type of through hole resistor.

The UB5C-240RF8 is a precision resistor designed specifically for use in high-reliability, high-voltage, and high-power applications. It has a maximum power rating of 180 watts and a maximum continuous voltage rating of 4000 volts. It features a low 1.4 total inductance, excellent temperature stability, and low lead RMS noise. It is protected against reverse polarity and has an integrated current limiter, making it suitable for use in a variety of high-power, high-voltage applications. The UB5C-240RF8 is a low-cost solution for applications requiring a precision, high-voltage resistor.

The working principle of the UB5C-240RF8 is based on the concept of Ohm’s law. Ohm’s law states that the current passing through a resistor is directly proportional to the voltage applied to it. Therefore, when a voltage is applied to the resistor, a current will flow through it. The current flowing through the resistor will be limited by the resistor’s resistance, and this resistance is determined by the physical size of the resistor and the material used to construct it. For instance, if the specific resistor is made with a thin metal wire, then the resistance will be higher than if the same resistor is made with a thick metal wire.The UB5C-240RF8 is designed to be a high-power, high-voltage resistor, and as such, it is made with a thick metal wire to ensure a low resistance. This allows it to handle high currents and voltages with minimal heating and losses.
