Through Hole Resistors are a type of resistor that are installed into a printed circuit board (PCB) using a leaded assembly process. The most common type of through-hole resistor is the RN65C7320FRSL, which is a thick film resistor that provides greater power ratings than many other types of resistors. There are a variety of applications and important working principles associated with this particular type of resistor.

RN65C7320FRSL Application Field

The RN65C7320FRSL is a thick-film resistor, which is designed to be used in the automotive, indoor, and outdoor industrial environments. It is capable of operating in temperatures ranging from -55°C to 150°C and is ideal for applications with heat management challenges. This resistor is also suitable for applications requiring a high degree of thermal and mechanical stress, such as in exposure to shock, vibration, or humidity. Additionally, its high temperature performance and high power capability make the RN65C7320FRSL an excellent choice for automotive industry applications.

The RN65C7320FRSL is also suitable for use in high power applications, such as power conversion systems and motor control systems, as well as for various resistance sensing and switch control applications. Furthermore, this type of resistor has excellent tolerance capabilities which make it suitable for use in applications requiring a stable resistance over a wide temperature range. This is particularly beneficial in applications such as temperature measurement, power management systems, and power conditioning systems.

RN65C7320FRSL Working Principle

The RN65C7320FRSL is a thick-film resistor with a resistance value set by a pre-programmed resistive element deposited onto a substrate. This type of resistor is a fixed device, and its resistance value does not vary with temperature variation or voltage. The difference between the RN65C7320FRSL and other types of resistors is the high power capacity. This resistor is capable of handling up to 10 watts of power. As a result, it is often used in high power applications where more power is required than traditional resistor types can provide.

The RN65C7320FRSL uses a traditional four-terminal configuration, with two resistive elements connected in parallel across the center two terminals. One of the resistive elements is “variable”, and the other is “fixed”. When a potential difference is applied to the two resistive elements, the current will flow through the variable element and a voltage will be developed across the fixed element, thus establishing the resistance. This voltage will remain constant even when the current through the variable element is reduced, so the resistor will maintain its resistance value over time.

In addition to its resistance, the RN65C7320FRSL also has a tolerance rating, which is an indication of how much the resistance can vary when compared to the nominal value. This tolerance rating is typically 5% of the nominal value and indicates the amount of variation that is acceptable for the resistor to maintain its rating. The RN65C7320FRSL also has a maximum working voltage rating, which is the highest voltage that the device can safely operate at.

Conclusion

The RN65C7320FRSL is a thick-film resistor with a wide range of applications in the automotive, indoor, and outdoor industrial environments. It is designed to provide high power capability and excellent tolerance capabilities and is suitable for applications requiring a stable resistance over a wide temperature range. It is also capable of handling up to 10 watts of power, making it an excellent choice for high-power applications. Finally, its four-terminal configuration ensures that the resistance value is maintained over time, even when the current through the variable element is reduced.
