In analog circuits, it functions as an ac coupling capacitor for filtering signals.

Working Principle

The RN70C2001FB14 is a non-inductive resistor that operates based on Ohm’s law. Ohm’s law states that the electric current passing through a resistor equals the voltage applied over the resistor multiplied by its resistance. By connecting a given resistor to a source of voltage, the current can be limited or regulated. The RN70C2001FB14 is constructed from a metal-oxide-semiconductor material with a metal base that can be of different sizes and shapes. The material is then heated, cooled, pressed, and coated before it is ready to be used. The metal base dictates the relevant mechanical properties such as the size, shape, weight, and surface area.

The RN70C2001FB14 has a fixed resistance value of 20 kilo-ohms and a power rating of a 0.125 watts. The maximum operating temperature is rated at +125 °C. The non-inductive design means that the resistor does not have an inductive or magnetic component, making it more suitable for applications that involve high frequency signals. The RN70C2001FB14 also offers excellent stability and tolerance, making it a favorite among electronic engineers for both analog and digital circuit designs.

Conclusion

Through hole resistors, such as the RN70C2001FB14, are versatile components with countless applications. A major benefit is their low cost and simple construction. The RN70C2001FB14, in particular, is an excellent choice for automotive, circuit protection, mixed signal/analog circuits, and many other applications. It features a fixed resistance of 20 kilo-ohms, an excellent tolerance and operating temperature, and a non-inductive design for greater compatibility with high frequency signals.
