Through Hole Resistors

Through hole resistors are a type of resistor used in printed circuit board (PCB) designs, where a resistive element is mounted within a physical structure that is placed through an opening in the board. The structure consists of a coefficient of fill and a substrate of insulating material or material that has good heat dissipation characteristics. It is most often used for applications where there is not much surface area available for a surface-mounted resistor and where power dissipated by the resistor must be carefully managed due to its limited size and area.

RN60C4640FBSL Application Field and Working Principle

RN60C4640FBSL is a high power through hole resistor with a resistance value of 4.6kohm and a dissipated power of 1W. It is used in a variety of applications such as lighting, LED, automation, instrumentation, aerospace, and military. Its working principle is similar to that of other through hole resistors. It consists of a resistance element connected to two leads that are then mounted to the board. The leads are positioned and secured by soldering, and the resistor form is filled with insulating material.

This particular type of resistor is specifically designed for power applications where heat dissipation is of the utmost importance. The design of the resistor allows for the efficient dissipation of heat away from the component, preventing potential damage due to heating. In addition, the RN60C4640FBSL is designed for high voltage applications, making it suitable for devices that may be exposed to high voltage levels.

Finally, the RN60C4640FBSL is capable of dealing with alternating current (AC) and direct current (DC) flows. The design of the leads allows for a relatively low impedance that enables the resistor to happily accept both AC and DC signals.

Benefits of High Power Through Hole Devices

Using through hole resistors can provide a number of advantages over other resistor designs, including:

• Able to handle higher current levels due to a larger surface area and the ability to dissipate heat away from the component.
• Less kinetic energy is dissipated as heat, thanks to its larger thermal capacity.
• Easy installation and more secure connection due to its through-hole mounting.
• Higher voltage ratings than surface mount resistors.
• Broad compatibility with many different types of circuit board materials due to its ability to work within tight confines.
• Cost effective due to its larger manufacturing process.

The increased power and efficiency that comes with through hole resistors makes them an ideal choice for a wide range of applications, including safety-critical applications such as aerospace and military applications.
