Through-hole resistors are ubiquitous components in every circuit design, and H851KFDA components are no exception. This resistor is designed specifically for use in high-temperature, high-voltage, and high-current applications - saving time and money for designers and engineers alike. Let’s take a look at the application field and working principle of this resistor.

Applications: H851KFDA resistors are an excellent choice for applications where high-temperature, high-voltage, and high-current are a concern. The resistor is made from high-quality cyclic polysulfone and its dielectric is a type of high-density, high-permeability ceramic material, making it highly resistant to thermal shock and a good choice for moderately high-voltage applications. Additionally, the resistor has a current rating up to 65A, making it suitable for high-current applications. H851KFDA resistors are also ideal for applications where size is a factor, such as when using through-hole PCB design, as this resistor is only 12mm in diameter and has a height of 10mm.

Working Principle: The working principle of the H851KFDA is relatively simple. Its cylindrical construction features an internal, insulated coil, which is designed to react to current passing through it by dissipating heat. When current is passed through, the internal coil correctly and precisely creates a resistance, limiting and controlling the flow of current. This effectively allows engineers to adjust and calibrate the current output of specific circuits.

The construction of the H851KFDA also allows for excellent heat dispersion, as its shape reduces the concentration of heat on any one single point. This reduces the chances for thermal shock, which can damage delicate components. Additionally, the resistor’s construction also aids in controlling noise created by the current flows.

Finally, the H851KFDA is extremely reliable due to its construction. Its components are designed to withstand temperatures up to 200°C, have a maximum voltage rating of 205VAC, and have a current rating of up to 65A - making it suitable for a number of applications. Additionally, the resistor has a long life expectancy of over 15,000 hours and meets IEC, UL and RoHS standards.

In conclusion, the H851KFDA is an excellent component for designers and engineers working on high-temperature, high-voltage, and high-current applications. Its design ensures reliable current output, excellent heat dispersion, and noise control, making it an ideal choice for through-hole PCB designs. As such, the H851KFDA is an extremely useful and practical component - making any circuit design successful.
