Through Hole Resistors – FMP300FRF73-143R Application Field and Working Principle

There is no doubt that through hole resistors are one of the most important components when designing an electronic system. From providing protection against power surges, to maintaining balance between components in a circuit – their importance can hardly be overestimated. One of the most sought after through hole resistors is the FMP300FRF73-143R, manufactured by Philips Electronics. This article will discuss its application field and working principle.

Application Field

The FMP300FRF73-143R through hole resistor is typically used for high frequency applications (over 100MHz) and surge protection devices, due to its excellent durability and high current-handling capacity. It can be used for a wide range of applications, including television and radio receivers, automatic vending machines, cars, navigation systems, and audio-visual equipment.

Due to its capability of transferring power in a reliable and safe manner, it can also be used in other types of applications, such as uninterruptible power supply systems, medical equipment, energy meters, HVAC systems, and even cellular phones. The FMP300FRF73-143R can also be used in gate drives, servo motors, switching power supplies, and power amplifiers, to name a few.

Working principle

The FMP300FRF73-143R through hole resistor operates on the principle of passing an electric current through a conductive element. The conductive element is usually made of metal, and is arranged in a circular pattern to provide the most efficient current-handling capacity. When an electric current passes through the resistor, it generates a voltage drop (the voltage across the resistor), which is proportional to the intensity of the current.

A typical resistor consists of two terminals, each with an electrically conductive element in between them. When power is applied, the resistor will generate a voltage drop across the terminals, which in turn creates a resistance. This resistance enables the resistor to reduce the current that can flow through, thereby protecting other components in the circuit.

The FMP300FRF73-143R features a high current-handling capacity, which makes it ideal for applications that require heavy-duty usage. Additionally, its solid construction ensures that it can operate in temperatures as high as 150 degree Celsius, and still maintain its durability and performance.

Conclusion

The FMP300FRF73-143R through hole resistor is a highly versatile component that can be used in a wide variety of electronic systems. Its high current-handling capacity and excellent durability make it a popular choice in many applications, such as television and radio receivers, automatic vending machines, cars, navigation systems, and audio-visual equipment. Additionally, its operation is based on the principle of passing an electric current through a conductive element, leading to a voltage drop across the resistor.
