Through hole resistors are a common type of electronic component used in many circuit applications. The PNP4WVFT-73-4R7 through hole resistor is no exception. This resistor is a four-terminal resistor of the NTC (Negative Temperature Coefficient) type and is often referred to as a "PTC" type resistor.This through hole resistor is designed to provide circuit protection in power supplies, amplifiers, and other applications that may require a component that is able to resist changes in temperature and stay stable at higher temperatures. It has low thermal coefficient of resistance and thus is highly reliable in its intended applications.The PNP4WVFT-73-4R7 through hole resistor has some unique features that make it suitable for use in many applications. It contains a small size ceramic body that is capable of dissipating heat quickly and efficiently. It also contains a PTC (Positive Temperature Coefficient) die which helps to resist changes in temperature. The four terminals of this through hole resistor enable it to operate as a temperature-sensing device in a power supply or amplifier application. The central terminal is used for signal input. The output terminal is connected to ground or is left open, depending on the requirement of the application. The fourth terminal is connected to the PTC die and it is the \'temperature sensing terminal\' which detects the temperature change.When the temperature increases, the resistance of the PTC increases and the voltage applied to the PTC decreases, resulting in a decrease in the output voltage. This decrease in the output voltage protects the power supply and the amplifier from any over-voltage or over-current condition. When the temperature decreases, the output voltage increases, enabling the power supply and the amplifier to function normally.In conclusion, the PNP4WVFT-73-4R7 through hole resistor is a four-terminal NTC type resistor which is highly reliable and efficient in the power supply and amplifier applications. It provides protection against over-voltage and over-current conditions due to its PTC die and its ability to reduce the output voltage when the temperature increases.
