Introduction to Through Hole Resistors

Through hole resistors are one of the most common types of electrical resistors used in circuits. Through hole resistors are available in various power ratings, from as low as a fractional watt to several kilowatts. They perform the same basic task as other resistors, but are designed to be mounted directly into a circuit board instead of into a separate housing. The form and construction of a through hole resistor makes it ideal for use in printed circuit boards. Through hole resistors are available in a variety of shapes and sizes, depending on the application and installed device. The main type of through-hole resistor is the axial-lead through hole resistor, and it is the one most commonly used in printed circuit boards.

RSF100JR-73-0R39 Application Field and Working Principle

The RSF100JR-73-0R39 is an axial-lead through hole resistor with a resistance value of 10 ohms. It is a radial leaded resistor, which means that it has two leads that stick out in opposite directions. The ends of the resistor are made from a corrosion-resistant Nickel-Chromium alloy, which provides a high degree of electrical stability and durability. The RSF100JR-73-0R39 is designed for use in printed circuit boards and other electrical circuit applications. The resistor is typically used to provide a small amount of resistance to a larger circuit. This allows for the reduction of current within the larger circuit, which can help maintain a steady voltage or current flow. The resistor is constructed from a ceramic core, which is coated with an insulating material and then encased in a plastic casing. This helps protect the resistor against external influences such as dust and moisture. The ends of the resistor are connected to two leads, which then pass through the circuit board and are soldered directly to the board. The resistance of the resistor is determined by the ceramic core material and the length of the leads. The longer the leads, the higher the resistance. Likewise, the higher the dielectric material used to insulate the core, the higher the resistance. In addition, the shape of the resistor can also affect its resistance. For example, a resistor with a curved shape will have a higher resistance than one with a straight shape.

Conclusion

Through hole resistors are essential components in any printed circuit board. The RSF100JR-73-0R39 is an axial-lead through hole resistor designed for and commonly used in this application. The resistor is designed to provide resistance to the larger circuit, allowing for a steady flow of current or voltage. The ceramic core is coated with an insulating material and then encased in a plastic casing. The length of the leads and shape of the resistor determine the resistance of the resistor and affect its performance.
