Through Hole ResistorsThrough hole resistors are one of the oldest basic electronic components still in use today. A resistor is a passive two-terminal electrical component that limits or opposes the flow of electric current. Through hole resistors can be divided into two main categories: fixed resistors and variable resistors. Fixed resistors include carbon and metal film resistors, whose resistance value can be determined by its physical dimensions. Variable resistors include potentiometers, trimmers, and rheostats, throwing a variable resistance into an electric circuit. One of the most popular through hole resistors is the PF2472-43RF1. Originally designed for the automotive industry, the PF2472-43RF1 is a four-terminal, surface mount device designed to be mounted to printed circuit boards and used to control the voltage and current in a variety of industrial and automotive applications. The PF2472-43RF1 is an effective way to limit the amount of power available to a circuit. The device can be used to limit the current to a given level, regulate the voltage, protect electronic components from sudden surges in power, and even provide isolation between two circuits. Its four terminal design allows for better control over its operation and can help to ensure that it operates properly.The PF2472-43RF1 is designed for low-power applications, with its maximum power rating of about 0.33 watts. Its standard resistive range has three operational positions, with the resistance value of 2.7K ohms when in the first position, 4.3K ohms when in the second position, and 8.2K ohms when in the third position. The PF2472-43RF1 includes a unique feature in which the resistance can be adjusted within certain ranges by turning a small knob, allowing it to be easily adjusted for different applications.When the PF2472-43RF1 is in operation, a temperature rating of -25 to 155 degrees Celsius is used. At this temperature, the PF2472-43RF1\'s life expectancy is estimated at 1,000,000 cycles, making it an ideal choice for applications requiring a long life expectancy or for arduous environments. The PF2472-43RF1 also has several environmental protection features, such as sulfur-resistance, that make it suitable for outdoor use and provides protection against exposure to extreme temperatures. Its resistance range is also quite wide, with a range of 0 to 10KHZ. This allows it to be used in a wide variety of applications and for a broad range of frequencies, making it an ideal choice for automotive and industrial applications that require an accurate and reliable resistor.In summary, the PF2472-43RF1 through hole resistor is an ideal choice for a variety of automotive and industrial applications, with its low-power ratings, temperature ratings, environmental protection features, and resistance range. The ability to adjust its resistor value within certain ranges further makes it a valuable tool for controlling power in a variety of applications.
