Through Hole Resistors are a critical component of many electronic systems. As such, their performance and reliability are of utmost importance. The PF2472-3RF1 is an example of a robust, reliable through hole resistor. This article will discuss the generic application field and working principle of the PF2472-3RF1.

The PF2472-3RF1 is designed for use in audio frequency (AF) applications. It has a low net resistance of ≤70 milliohms. This low resistance provides the system in which it is installed with the required AF signal attenuation. In addition, the resistor also has a low noise-to-signal ratio of 1.2dB, making it suitable for demanding AF applications.

The PF2472-3RF1 is specifically designed for extreme operating conditions, such as high temperatures, high pressure, and extreme humidity. This is possible due to the resistor’s piezo-resistive nature. Piezo-resistive resistors are composed of two parts. The first part is a metal element composed of a resistive material, such as Manganin or Constantan. This material is capable of converting an applied mechanical force into a corresponding electrical resistance. The second part of this type of resistor is a dielectric material, such as ceramic or polyester, which is sandwiched between the metal material to create a capacitive element. This capacitance is able to hold a static electric charge, which can be used to measure resistance.

The PF2472-3RF1 through hole resistor also has a number of properties that make it an ideal choice for AF applications. It has an incredibly low total harmonic distortion (THD) value, at 0.1%, ensuring that the signal received is accurately reproduced. It also has an exceptionally high frequency response, up to 40kHz, making it ideal for applications involving high-fidelity audio. Additionally, the resistor features low power dissipation, allowing for wide frequency bandwidths without undesirable heat generation.

The PF2472-3RF1 through hole resistor is therefore an excellent choice for those looking for an exceptionally reliable, robust, and low power consuming resistor for their AF applications. Its piezo-resistive nature enables it to withstand extreme operating conditions, while its low THD value, high frequency response, and low power dissipation make it suitable for a wide range of AF applications. Finally, its incredibly low resistance makes it an ideal choice for those installations requiring precise AF signal attenuation.
