Through Hole Resistors - RN65C1540FB14 Application Field and Working Principle

Through hole resistors are a type of passive components used in circuits for lowering voltage, limiting current, and providing bias to certain signals. The specific product RN65C1540FB14 is a component within the category of through-hole resistors and can offer several different functions depending on the application it is used for. Within this article we will be discussing the application field and working principle of the RN65C1540FB14 and how it is used in a circuit.

What is the RN65C1540FB14?

The RN65C1540FB14 is a type of through-hole resistor that is composed of a precise amount of metal material deposited on a ceramic core. The metal material and ceramic core are both shown in the adjacent image. The precise wording given to the resistor, RN65C1540FB14, refers to the resistance of the metal material layer along with the dimensions of the ceramic core. The resistance of this particular product is 15.4 ohms, which is relatively high even for through-hole resistors. This resistor is a type of “fixed” resistor, simply meaning that once it is installed within the circuit its resistance will not be dynamically changing in accordance with other factors. In terms of size, the RN65C1540FB14 has a diameter of 6.5 mm and a length of 15mm. This is a relatively large size for a through-hole component, however, it can be easily mounted into larger circuit boards with the appropriate tools and methods.

Application Field:

The RN65C1540FB14 is well suited for a variety of purposes in or both commercial and consumer electronic applications. In particular, the product is ideal for applications where high precision and a reliable level of power should be expected. The 15.4 ohm resistance value can be used in a variety of scenarios, with the most common being for limiting current within the circuit and providing a specific voltage drop where needed. Due to the large size of the component, it is not suited for applications that have a specific size constraint. Additionally, due to the relatively high resistance value it is not ideal for applications that are looking for a high-level of reactivity and small amplitude current fluctuations. Larger packages are much better suited for this task.

Working Principle:

The working principle of the RN65C1540FB14 is a relatively simple one. Simply put, when a voltage is applied to one side of the Resistor, it will create an electrical current based on Ohm\'s law, the formula of which is given by I=V/R. This current will then pass through the component from one side to the other at a slow rate due to the resistance of the metal layer. In simpler terms, the component produces a type of energy logjam, cutting down current to rate that is determined by its 15.4 ohm resistance value.In terms of output, the RN65C1540FB14 will have a Voltage drop between the two sides equivalent to the voltage applied multiplied by the resistance of the component.

Conclusion

The RN65C1540FB14 is a relatively simple yet high precision through-hole Resistor ideal for applications that require a reliable level of current limiting and/or voltage drop. The high resistance value of the component makes it best suited for applications that require a steady output as it has a tendency to slow down current pass-through. The current size of the component, however, makes it not the best choice for very size-constrained projects.
