Through Hole Resistors have been one of the essential components in electronic circuits for many years. The most common type of resistor today is the PNP4WVFR-73-1K2, which is designed to provide low power resistive voltage and current in circuits. It is widely used for circuit protection, current sensing and motor control.

The PNP4WVFR-73-1K2 is composed of an electrically insulated metal plate, a resistive element mounted on the metal plate, a connector, and two mounting screws. It is also composed of two resistive elements, usually made of copper, gold, or other metal material. The two resistive elements are connected in series, creating a voltage divider circuit.

The PNP4WVFR-73-1K2 is mainly used in the control of power supplies, circuits with low power supply voltages, and in motor control. It is also used in applications such as DC-DC converters, voltage regulators, and voltage limiter circuits. It can also be used for current sensing applications such as current measurement, overload protection, and motor speed control. The PNP4WVFR-73-1K2 is a rather small device, with a diameter of 3mm and a height of 11mm, allowing it to be easily integrated into many circuits.

The working principle of the PNP4WVFR-73-1K2 is based on the idea of a voltage divider, which is a circuit that divides a voltage into two equal measurement elements. As the voltage is applied across the two resistive elements, the voltage will be absorbed through a resistive element and then moved across the other element. This creates a feedback loop, where the voltage is reduced as it moves through the resistive elements.

The PNP4WVFR-73-1K2 also has the added advantage that it can be used in high power, high voltage applications. By setting the voltage across the resistive elements higher than the power supply, the total resistance reading of the circuit will increase, enabling the device to be used in higher powered applications. This is why the PNP4WVFR-73-1K2 has become so popular.

The PNP4WVFR-73-1K2 is a reliable electrical component, with a long life expectancy. It is also easy to install and does not require the use of any additional components. It is an essential component for low power circuits, as it adds a layer of protection and can be used as a voltage or current sensor. With its small size and reliable performance, the PNP4WVFR-73-1K2 is one of the most used Through Hole Resistors today.
