Introduction to Through Hole Resistors

Through hole resistors are components used on circuits to control the flow of electricity in the form of electrical signals. They have various shapes, sizes and values of resistance, and are made up of one, two or more parallel strands of wire that is coiled and then covered by a plastic that holds the strands together. The component is then put through a thermal plating process that permanently embeds the coil into the plastic for increased durability and longevity. Through hole resistors are chosen for particular applications depending on the voltage and current carrying capacity of the resistor, and the length or width of the resistor.

RN70C6981FBSL Application Field and Working Principle

RN70C6981FBSL belongs to the range of through hole resistors manufactured by Riedon. It is a low-value resistor used for testing and prototyping applications and has an operating voltage of 250VAC. It has a tolerance of 0.25%, and its power rating is 0.25W. The resistor has a temperature co-efficient of -55 ppm/°C, and has a resistance range from 1KΩ to 22MΩ. The resistor is package in leaded housing and is available in both axial and radial configurations.

The operating principle of RN70C6981FBSL is simple. The resistor is composed of coiled metal strands, and the resistance of the coil changes as the current traveling across it changes. As the current passes through the coil, it creates a magnetic field which creates a resistance to the current. By changing the number and the length of the coils in the resistor, you can change the resistance of the resistor. This allows for a wide range of resistances, as well as power ratings, that can be used for different applications.

Conclusion

Through hole resistors are a common component used for controlling the flow of electric current. RN70C6981FBSL is a low-value resistor with an operating voltage of 250VAC and is available in both axial and radial configurations. It has a tolerance of 0.25%, a power rating of 0.25W, and a resistance range from 1KΩ to 22MΩ. The resistor works on the principle that as the current passes through the coiled metal strands, it creates a magnetic field which creates a resistance to the current. By changing the number and the length of the coils, the resistance can be changed. This type of resistor is ideal for testing and prototyping applications.
