Through Hole Resistors

RNF14CAC45K3 is a through hole resistor with metal finned construction. Through hole resistors are by far the most popular resistor type. Together with non-through hole resistors, they form the two main types of resistors available. As a through hole part, RNF14CAC45K3 mounts mechanically in a circuit board hole and connects electrically to the hole’s plated-through-hole. Sometimes referred to as through-hole resistors, they are manufactured as either fixed resistors or variable resistors. Fixed resistors are available in a wide variety of resistance values -- an option exists for almost every circuit design.

As its name suggests, through hole resistors are mechanically and electrically affixed to the printed circuit board (“PCB”) using through holes, mechanically supporting the weight of the part and ensuring a good electrical connection. This makes them very reliable for use over the lifetime of the product in hostile environments such as high temperature and vibration. Their low cost and ease of use make them particularly popular in high volume applications. They can be used to make fine resistance adjustments because some of them are designed for variable resistance by turning a knob or a screw. Through hole resistors are also usually the type used in precision resistive networks or filters.

Working Principle

RNF14CAC45K3 is a through hole resistor, as mentioned above. The working principle of a through hole resistor is as follows: with the help of a process that is called electroplating, an electric current is used to plate a thin layer of metal onto an insulatable base, usually brass or nickel-plated brass. This metal layer is then coated with a thin elastomer layer whose thickness depends on the complexity of the resistor and the accuracy of the resistor required. The resistance value of this resistor is determined by the length of the elastomer layer, the width of the metal plating, and the electrical properties of the substrate. In addition, because through hole resistors are connected directly to a printed circuit board, they are relatively stable against vibration and shock. This makes them a great choice for use in military, aerospace, and industrial products that require a stable resistor.

As one of the most common components used in electronic circuits, through hole resistors are being used in a variety of application fields, including communication equipment, medical electronic devices, automotive electronics, solar electronic systems, and LED lighting. This is not a complete list, however, as they can be used in nearly any application requiring electrical or electronic components.

Conclusion

RNF14CAC45K3 is a through hole resistor, one of two main resistor types. Through hole resistors have the advantages of sturdiness and reliability due to being mechanically and electrically attached to the printed circuit board. The resistance value of the RNF14CAC45K3 is determined by the length of the elastomer layer and the width of the metal plating. They are used in a variety of application fields, including communication equipment, medical electronic devices, and automotive electronics, due to their stability in hostile environments. In conclusion, RNF14CAC45K3 is a through hole resistor with many features and applications.
