Resistors are electronic devices used to control current, making them a delicate yet important feature of most electrical circuits. Of the various resistor designs available, the through-hole resistor is a popular choice in both commercial and industrial settings. But among through-hole resistors, the RNF14DTC698R stands out due to its unique design and purpose.

The RNF14DTC698R was designed to be used in high-temperature power management applications such as automotive power supply systems and semiconductor power modules. This makes it a great choice for applications where a significant amount of heat is expected. The key feature of this through-hole resistor is its power rating. It is rated at a very impressive 700W, so it is capable of withstanding extreme temperatures and high power levels. Other features include a temperature coefficient of -55 ppm/°C, an operational temperature range of -55°C to +150°C, and a maximum working voltage of 500V.

In terms of construction, the RNF14DTC698R is composed of a metal core with two litz wires and two insulated substrates that form the two resistive elements. The metal core is designed to ensure even heat distribution and increase its heat resistance. The two litz wires act as the connection between the two resistive elements and are also insulated for safety. The two substrates, or resistors, are composed of a ceramic material that has been sintered with a dopant material and given a resistor value. The resistor value can range from 0Ω to 2.2MΩ, depending on the model.

In terms of functionality, the RNF14DTC698R is designed to provide an electrical path for electrical current to pass through. This path is determined by the ohmic value of the chosen resistor. When electrical current passes through the resistor, a proportional amount of current is dissipated as heat. This means that the amount of heat generated by the resistor depends largely on the amount of current and the chosen resistor value.

In summary, the RNF14DTC698R is an excellent choice for heat- and power-management applications, such as automotive power supplies and semiconductor power modules. Its impressive power rating and temperature coefficient make it well suited for applications requiring large amounts of heat resistance. Additionally, its construction is designed to ensure even heat distribution and safety. With its wide range of ohmic values, the RNF14DTC698R is a great choice for those looking for an economical, long-lasting, and reliable through-hole resistor.
