PF2472-39RF1

PF2472-39RF1 Application Field and Working Principle

PF2472-39RF1 resistors belong to the family of through-hole resistors, which are passive devices that reduce voltage and current flow and measure electrical power in electronic circuits. Through hole resistors are one of the most commonly used components in circuit board assembly. Since they come in a variety of shapes, sizes, and materials, there is a wide range of options for engineers when selecting the most suitable component for their applications. Through hole resistors are assembled by inserting the leads through the metalized holes and soldered to the circuit board. This makes them especially useful for high-power systems, as the metalized holes provide higher power-handling capabilities compared to surface mount resistors. PF2472-39RF1 resistors are usually configured as four- or five-digit designations, with the first three digits specifying the resistance value, and the rest of the digits specifying tolerance and temperature coefficients. The PF2472-39RF1 designation denotes a resistor with a nominal resistance of 24.72 kohms, a tolerance of ± 0.2 % and a temperature coefficient of 39 x 10–6/°C. The PF2472-39RF1 is rated for power dissipation levels up to 10 W . It is commonly constructed from metal oxide film, a reliable, cost-effective substrate material that has been widely used in the manufacture of resistors. These resistors have a wide operating temperature range from –55°C to +125°C and can withstand high-temperature soldering up to 260°C for 10 seconds. When supplying a PF2472-39RF1 resistor, the current should always be kept below the rated power level. The resistor’s resistance value can also be modified by adjusting its temperature coefficient and changing the applied voltage. This feature is often used in applications such as temperature compensation, oscillators, and crystal filter circuits. The PF2472-39RF1 resistors have been proven to be the most efficient and reliable solution for applications requiring high-power dissipation, low resistance value, and wide temperature range. Engineers can rely on these components to provide long-term, reliable performance.
