Through Hole Resistors

One of the most common type of resistors is the through-hole resistor (THR) which is designed to be placed into a hole drilled out of a PCB, providing electrical connection between traces on the surface of the board. The design of a THR allows for a variety of types, sizes, and power ratings depending on the application.In this article, we’ll explore the common applications of the H4P20KFCA THR, the various aspects of its power rating, and the working principle that drives its performance.

Applications

The H4P20KFCA THR is designed for applications that require high power, voltage, and current handles. This type of resistor has a much higher power rating than most other THR models, offering up to 20 kW of continual power absorption. This makes it an ideal choice for high-power applications, including industrial motor drives, power conversion and conditioning circuits, and automotive electronic systems.Additionally, this THR is sizable enough to accommodate heavier wire gauges and higher current demands, making it perfect for applications in which the THRs need to be mounted in difficult to access areas or situations with limited available space.

Power Rating

The H4P20KFCA THR is rated to handle up to 20 kW of continuous power. It is also designed to withstand up to three times that amount for shorter-duration peak loading periods, such as those encountered during inrush current spikes.Higher power ratings are constructed using larger-diameter, copper-clad steel construction to provide increased thermal and electrical performance. Additionally, the H4P20KFCA THR also features a robust ceramic outer sheath to provide maximum thermal and electrical insulation.

Working Principle

The working principle of the H4P20KFCA THR is based on the principle of Ohm’s Law. According to this law, electricity flows through a conductor proportional to its resistance, which is determined by the conductivity of the material. The H4P20KFCA THR’s resistance is determined by the number of turns of wire inside the cylinder divided by the total cross-sectional area of the cylinder.The amount of electricity that is able to flow through the THR depends on the resistance created by the device and the voltage applied to it. For the H4P20KFCA THR, the amount of resistance is set to accommodate the amount of power that can safely run through it. This also ensures that the device will not heat up to unsafe temperatures.

Conclusion

The H4P20KFCA THR is a popular through-hole resistor model that offers excellent performance and an ideal solution for a variety of high-power applications. Its robust construction allows it to handle a continuous load of up to 20 kW and peak loading periods of up to three times that. Its working principle, which is based on Ohm’s Law, allows it to act as a conductor of electricity proportional to its resistance, ensuring it does not heat up to unsafe temperatures. For these reasons, the H4P20KFCA THR is an optimal choice for high-power applications in a range of industrial and automotive systems.
