Through Hole Resistors are widely used in many applications, such as electronic devices, circuit protection, and power supplies. The PNP4WVFT-73-620R is a type of Through Hole Resistor which is unique in terms of its physical size and electrical properties. This article will discuss the application field and working principle of this device.

The PNP4WVFT-73-620R is a Through Hole Resistor with a 0.62Ω resistance, and it is categorized as a ‘low ohm’ resistor due to its low resistance value. It has a maximum power rating of 1/8 watt, a response time of 8 milliseconds, and a tolerance of ±1%. The device is available in two case sizes, the standard case and the extended case. The standard case measures 7.16 x 10.21 x 4.27mm while the extended case measures 8.61 x 11.61 x 5.03mm. The device is also available in different package types, such as surface mount, through-hole, and radial.

Due to its low resistance and high power rating, the PNP4WVFT-73-620R is well-suited for applications such as current sensing, ground loop mixing, and power surges. It is also well-suited for precision voltage regulation due to its low tolerance. In addition, this device is suitable for use in telecommunications equipment and other high-speed pulse applications due to its fast response time.

The working principle of the PNP4WVFT-73-620R is similar to that of a standard resistor. When a voltage is applied across the terminals of the device, the current flowing through it generates heat, which is dissipated to the air through convection or to a heatsink. The resistance of the device decreases as the temperature increases due to the PTC thermistor property of the device. This is in contrast to standard resistors, which have a constant resistance over a wide range of temperatures. This property makes the PNP4WVFT-73-620R well-suited for use in temperature dependent circuits.

In addition, the PNP4WVFT-73-620R also has a wide range of preferred operating temperatures. This device can operate at temperatures ranging from -40°C to 125°C for extended periods of time, and it can handle temperatures up to 150°C for short periods of time. This makes it an excellent choice for applications that require reliable performance in high temperature environments.

The PNP4WVFT-73-620R is an excellent choice for applications requiring a low ohm, high power, and fast response time. Its unique PTC thermistor properties make it well-suited for temperature dependent circuits, and its wide operating temperature range makes it an excellent choice for applications operating in high temperature environments.
