Through Hole Resistors are a form of component that is used when there is a need for very high levels of power dissipation. They are often seen in high voltage applications because of their high current ratings and long life expectancy. The RR03JR75TB is one such Through Hole Resistor, which has many great features that make it ideal for a wide array of applications.

The RR03JR75TB is a 5 watt high power resistor with a 75 ohm resistance value. It is designed to be mounted on a printed circuit board or other substrate. Its design features a solid-state construction, which allows it to dissipate power in a more consistent and reliable manner. The resistor also features a dual-in-line package which ensures that it is easy to mount in tight spaces.

The greatest feature of the RR03JR75TB is its resistance tolerance. It has a very low resistance tolerance of just ±0.25%, meaning that its resistance value will remain extremely consistent over time. This makes the RR03JR75TB perfect for applications that require very precise resistance values as any changes in its value will be very minimal. This also makes it a great choice for high voltage applications, as the reliability of the resistor is essential.

The other great feature of the RR03JR75TB is its low temperature coefficient of resistance. The temperature coefficient is measured in ppm/°C and it quantifies the amount the resistance will change with changes in temperature. Lower temperature coefficients are desirable as they mean the resistor will be able to stay consistent under changes in temperature for longer periods. The RR03JR75TB has a low temperature coefficient of -60 ppm/°C, meaning that its resistance values remain consistent even under extreme temperature changes.

The working principle of the RR03JR75TB is fairly simple and straightforward. As with all Through Hole Resistors, it works on the principle of Ohm’s Law. This states that the current passing through a resistor is proportional to the voltage applied across it. As such, by applying an exact voltage across the resistor, an exact current can be achieved, and the resistance value can be calculated.

In conclusion, the RR03JR75TB is a perfect Through Hole Resistor for a wide range of applications. Its low resistance tolerance of ±0.25%, its low temperature coefficient of -60 ppm/°C, and its strong reliability all make the RR03JR75TB a great choice. Thanks to its easy to mount design and its solid-state construction, it makes it a great candidate for high voltage applications that require precise and reliable resistance values.
