It is often used in industrial equipment, including robotics, HVAC systems, and temperature measurement and control systems. The device is also popular in automotive circuits, as it offers superior performance compared to more traditional Through Hole Resistors.

Working Principle

Like all other resistors, the PNP7WVJR-73-470R operates by limiting the current flow between two points in a circuit. This is done by introducing a given amount of resistance, determined by the value of the resistor, into the circuit. The value of a resistor is typically indicated by a series of colored bands and is usually represented in ohms.

A simple example of how the PNP7WVJR-73-470R is used is in a linear DC motor. When the motor is turned on, a current will flow from the motor\'s power source to the motor\'s armature. This current will be limited by the PNP7WVJR-73-470R, as it introduces a given amount of resistance into the circuit. This resistance limits the amount of current flowing into the motor\'s armature, resulting in precise control over torque output and motor speed.

Conclusion

The PNP7WVJR-73-470R is a popular Through Hole Resistor due to its high accuracy and excellent stability over time and temperature. It is ideally suited for small space applications and is commonly used in industrial, instrumentation, and automotive circuits. The device operates by limiting the current flow between two points in the circuit by introducing a given amount of resistance, specified by the value of the resistor. In this way, the PNP7WVJR-73-470R provides precise control over current levels in DC motors, as well as in a variety of other applications.
