Through Hole Resistors

A through hole resistor, also called a leaded resistor, is an electronic component used to regulate current flow in an electrical circuit. It is largely used due to its simplicity, ease of use, and accuracy. The UL5C-4RF8 resistor is commonly used in the electronics industry for a variety of applications. This article will discuss the application field and working principle of UL5C-4RF8 resistors.

Application Field

The UL5C-4RF8 resistor is widely used in consumer electronics, for example in television circuit boards, DVD players and set-top boxes. Furthermore, the UL5C-4RF8 resistors can be used in high power applications such as ACs, refrigerators, and washing machines. Additionally, the UL5C-4RF8 is used for voltage supervisory circuits in automotive electronics applications. These resistors are also used in air conditioning, instrumentation and medical electronics.

Working Principle

Generally, when electric voltage is applied to a resistor, the current will flow through the resistor depending on its resistance value. This resistance value is represented as a set of standard EN values, for example, 2.2K or 10K. The UL5C-4RF8 resistors typically feature four fixed resistance values such as 1K, 2K, 4K and 8K. When voltage is applied to the UL5C-4RF8 resistor, a sequence of Ohms law will be involved. According to Ohm’s law, the electric current, I, through the resistor comprises of voltage, V, and the resistor’s resistance, R, obeying the mathematical equation I = V/R. In other words, the voltage drop across the UL5C-4RF8 is equal to the current I multiplied by the resistor’s resistance R.
