Through Hole Resistors, commonly abbreviated as THR, have been a popular choice in electronic components for many years. THR resistors are known for their excellent reliability, low cost, and wide range of operating temperatures. The PF2472-0R11F1 is a popular THR resistor designed for low-power applications. This article will discuss the application field and working principle of the PF2472-0R11F1.

The PF2472-0R11F1 is a low-power, radial leaded, ceramic, cylindrical thick film resistor. It is designed to operate continuously at power ratings up to 0.3 watts in ambient temperatures ranging from -55°C to +125°C and ratings up to 0.3 watts in high temperatures up to +150°C. The resistor is available in five different values - 0R0Ω to 0R10Ω - with tolerances ranging from ±0.5% to ±10%.

The PF2472-0R11F1 has a wide range of applications due to its low-power consumption, wide temperature range, and low cost. The resistor is commonly used in telecommunications, instrumentation, automotive, consumer electronics, and military applications. In particular, it is well-suited for providing over-voltage protection for sensitive components, such as lasers, relays, and motors.

The working principle of the PF2472-0R11F1 can be broken down into two components: thermal protection and electrical resistance. The thermal protection component prevents any damage to the device due to excessive temperatures by automatically shutting off the power supply to the resistor when the temperature limit has been exceeded. The electrical resistance component is a basic form of Ohm’s Law, where the resistance of the device is inversely proportional to the current flow through it. The lower the current, the higher the resistance and the greater the voltage drop across the resistor.

In addition to providing over-voltage protection, the PF2472-0R11F1 can also be used for voltage division, current limiting, noise reduction, and signal isolation. The resistor is also highly reliable and easy to use. The resistor is designed to provide repeatable and predictable performance and is designed to last for hundreds of thousands of hours. Finally, the resistor is also RoHS compliant, meaning it is free from any hazardous chemicals or materials, making it environmentally friendly.

In conclusion, the PF2472-0R11F1 is a low-power, ceramic, cylindrical thick film resistor. It has a wide range of applications due to its low-power consumption, wide temperature range, and low cost. Its working principle involves thermal protection and electrical resistance, and it can be used for overvoltage protection, voltage division, current limiting, noise reduction, and signal isolation. It is RoHS compliant and offers reliable and predictable performance.
