Through Hole Resistors have been in use within the electronics industry for many decades. As technologies develop, different types of resistors have been introduced to meet specific requirements. PNP4WVFR-73-10R is among such type of resistors.

The most common form of PNP4WVFR-73-10R is the through-hole type, which consists of a metal-film resistor element contained within an insulating tube. It is designed for applications which require both high precision and long-term stability. This type of resistor has low temperature coefficient of resistance (TCR) values, making them suitable for many temperature sensitive applications. Generally, the TCR value of resistors in this series is ±0.1%/℃.

The PNP4WVFR-73-10R resistor has a resistance range from 0.1 Ω to 10 kΩ and is available in different tolerance classes: ±5%, ±10%, ±1%, ±2%, ±2.5% and ±0.5%. It also has a maximum rated dissipation at 70℉ of 1/8 watt in radial and 1/8 watt in axial. The working temperature range for the PNP4WVFR-73-10R is between -55℃ and +155℃ Celsius.

The accurate positioning of the PNP4WVFR-73-10R resistor in the circuit board is ensured by its through hole design with double thrusts. When mounted on the board, these resists are axially supported by any two or three components of the board. This prevents radial-inclined strain and allows for proper contact with a lead wire or component.

The PNP4WVFR-73-10R resistor is an ideal choice for various circuit applications, its properties making it an excellent choice for low noise, low distortion, low temperature drift amplifiers and high voltage power supplies. It is also well suited for signal conditioning circuits, analog-to-digital conversions, and semiconductor switching circuits.

The working principle of the PNP4WVFR-73-10R is best understood through its equivalent resistance formula: R = r₀(1 + αT), where r₀ is the temperature resistance at 0℃, α is the temperature coefficient of resistance (TCR), and T is the temperature at which the resistor is operating. This means that the resistance of the resistor changes due to changes in temperature, such as when the board temperature increases or decreases.

Finally, the PNP4WVFR-73-10R resistor is an excellent choice for applications where temperature stability and accuracy are critical. Its through hole design allows for a great deal of flexibility in design, while its wide temperature range provides excellent stability and accuracy. Its low TCR value and long-term stability make it an ideal choice for temperature sensitive applications. Finally, its low dissipation rate and wide resistance range make it suitable for many circuits, from high precision audio applications to power supplies.
