Through Hole Resistors: PF2472-620RF1

A through hole resistor is an electronic passive component which has two lead wires extending from the body and protruding through a hole in the mounting surface of the board so it can be mounted. The most common type of through hole resistor on the market is the axial lead resistor. Its general composition is formed by four components: lead, core, shell, and base. The PF2472-620RF1 fixed resistor is one of these through hole resistor. In this article, the application field and working principle of this specific resistor is explored.

Application Field of PF2472-620RF1

The PF2472-620RF1 is a surface mount, lead free, RoHS compliant, fixed resistor and one of the most widely used through hole resistors. The major application fields of this resistor are in various industrial and consumer electronics such as computers, copiers, medical equipment and other audio and video electronic equipment. This resistor has a high tolerance of ±1% and a rated power of 0.125W. Its operating temperature is between -55°C ~ +125°C and its operating voltage range is 50 V, making it suitable for most electrical applications.

Working Principle of PF2472-620RF1

The working principle of the PF2472-620RF1 is based on Ohm\'s Law which states that current is equal to the voltage divided by the resistance (I = V/R). The resistor has two leads - one end connected to the positive side of the voltage source, the other end to the negative side. When the voltage is applied to the resistor, current flows through it proportional to the voltage. The current flow through the resistor is limited by the resistance, hence the name \'resistor\'. Different resistor models such as the PF2472-620RF1 have different levels of resistance which affect the amount of current that flows through them.

The PF2472-620RF1 has a metal oxide film which is formed from the deposition of a metal wire onto a ceramic substrate. The metal oxide film functions as an insulating material, thus forming a gap in between the metal wire where a dielectric material made from the material in the substrate is placed. The resistance value of the PF2472-620RF1 is determined by the width of the width band where the metal wire is deposited onto the substrate and the thickness of the dielectric material also affects the resistance value of the resistor.

Conclusion

The PF2472-620RF1 is a common type of through hole resistor that is used in various industrial and consumer electronics. Its application fields range from computers to medical equipment and its rated power of 0.125W and operating temperature of -55°C ~ +125°C make it suitable for most electrical applications. The working principle of the PF2472-620RF1 is based on Ohm\'s Law and its resistance value is determined by the width of the band and the thickness of the dielectric material within it.
