Through hole resistors are a type of resistor, which have terminals that are inserted into plated holes and placed onto a printed circuit board, allowing the passage of electric current between elements. The RNX025470KFHWF is an example of such a resistor which has specific uses and an associated operating principle.

In terms of usage, the RNX025470KFHWF is generally employed for higher power applications, particularly those for which the current is too high for a surface mount device. Its resistance value must remain stable over a wide range of temperatures and frequencies, and it is suitable for use with high-amplitude, broadband signals. The RNX025470KFHWF is also employed in applications requiring high-power supply rejecting components.

In terms of design, the RNX025470KFHWF features an axial lead, two end-terminals, and is generally used with axial-leaded printed circuit boards. Its maximum operating frequency is 305 kHz, and its temperature coefficient of resistance (TCR) is at most ±25ppm/°C. It has a maximum operating temperature of +150°C, a maximum pulse width of 400 µs, a capacitance fall time of 2.2ms and a wattage rating of 1/ 8Watt.

In terms of the working principle of the RNX025470KFHWF, it uses the blockage of current flow to create resistance due to the thickness of the material it is made from (carbon film). This creates a barrier to the passage of current, reducing its intensity and preventing over-heating from higher amplitudes. The resistance of each resistor is determined by the thickness and type of material used in its construction.

The use of the RNX025470KFHWF in various applications allows the current to be controlled according to the given requirement, so that the design is protected from potential over-heating and current issues while also ensuring greater accuracy and stability than with other resistors. Its resistive value and thermal stability also make the RNX025470KFHWF suitable for numerous and varied usage scenarios throughout the industry.

Overall, the RNX025470KFHWF is a robust and reliable through hole resistor, offering great performance in applications calling for high-power, high-amplitude signals. Its axial leads and design make it suitable for use with printed circuit boards, while its operating principle offers excellent resistance values when controlling current and preventing over-heating.
