Through Hole Resistors are a type of component widely used in the electronics industry. Primarily, they are used to reduce the voltage in a circuit so as to control the amount of current that flows. The RLR07C4993FSR36 is one type of through hole resistor, and it is favored for its high level of power per unit volume, its low thermal resistance, and its wide range of values. In this article, we will take a look at the application field and working principle of the RLR07C4993FSR36.

Application Field

The RLR07C4993FSR36 is primarily used in high voltage applications, typically above 550 volts. Furthermore, it is regularly used in circuits with high wattage outputs, mostly due to its excellent thermal resistance and high power per unit volume. The most common use is in the creation of resistors in power electronics, including power supplies, amplifiers, and rectifiers. The component is also useful in DC gate circuits, such as those found in electric cars, motors, and inverters, and other high current and power applications.

Working Principle

The RLR07C4993FSR36 works according to Ohm\'s Law, which states that increasing the voltage across a resistor causes an increase in the current. The component follows this principle by dissipating the current so as to reduce the voltage. This is due to the internal resistor element, which essentially resists current flow by converting some of the electrical energy in the circuit into heat. This is why the RLR07C4993FSR36 is so frequently used in high wattage applications, as it is highly capable of dissipating power and is relatively small.

The selection of the resistor value is determined by the type of current that needs to be resisted and the amount of voltage that needs to be reduced. For example, in circuit with high DC currents, a higher wattage resistor is typically employed. In contrast, for a low current circuit, a lower power resistor may be necessary. Also, if the voltage needs to be decreased by a small amount, then a lower wattage resistor may suffice.

Conclusion

The RLR07C4993FSR36 is a type of through hole resistor that is primarily used for power and high voltage applications. Its advantages include its high power per unit volume, its low thermal resistance, and its wide range of values. It works according to Ohm\'s Law, whereby the current is dissipated to reduce the voltage. The selection of the resistor value is determined by the type of current that needs to be resisted and the amount of voltage that needs to be reduced. Overall, the RLR07C4993FSR36 is a useful and versatile component for the electronics industry.
