Through Hole Resistors

Through hole resistors, a popular type of resistor that is named for its construction, are mainly used in applications where a large power dissipated requires the heat to be dispersed. These resistors are usually large, and can range from a fraction of an Ohm to several kilohms or even megohms.The PRNF14FTD499K is a through hole resistor that falls into this range of popular resistors. It is a fixed power device with a range of 0.25W to 2W, a capacitance range of 500pF to 5,000pF, and a working temperature range of -55°C to +125°C. This resistor has a variety of features not seen in other resistor types. These features include high-temperature stability, low-noise capabilities, contact reliability, and static protection. Additionally, the PRNF14FTD499K is a rugged device and is tough enough to be used in hostile environments and is able to withstand intense mechanical vibration and temperatures.The PRNF14FTD499K is constructed of a metallic material, typically either copper or aluminum, and then formed into a cylindrical shape. After, its electrical resistance is determined by the size and shape of the cylinder. Due to its construction and its features, this resistor is the ideal choice for applications that require high-power and high-temperature resistors such as power relays, motor starters, and automotive applications.The working principle of the PRNF14FTD499K is fairly straightforward. When an electrical current flows through the resistor, an electrical potential is created across its terminals, resulting in a resistance that is proportional to the amount of current flowing through it. This resistance is then dissipated in the form of heat, reducing the amount of electrical energy available to the circuit.In conclusion, the PRNF14FTD499K is a typical through hole resistor used in a variety of applications requiring high-power and high-temperature resistors. It features high-temperature stability, low-noise capabilities, contact reliability, and static protection; making it perfect for use in a course of hostile environments and is tough enough to withstand mechanical vibration and temperatures. Its working principle is simple, it Forms an electrical resistance proportional to the current flowing through it, and dissipates the energy in the form of heat.
