The MFR100FTF52-475K is a type of through hole resistor, and it is utilized for various applications, including in power supplies, audio amplifiers and automotive electronics. It is very important to understand the working principle of the device in order to determine its correct application. This article will discuss the application field and the working principle of the MFR100FTF52-475K.

The MFR100FTF52-475K is a fixed-value, through hole resistor. It is made of metal-film construction, and the resistor has a resistance value of 475K ohms. The device utilizes two axles to secure it to a circuit board, and the holes in the board have a diameter of 1.6mm. The axles also effect a secure connection to the board, to help ensure proper operation.

The MFR100FTF52-475K can be used as a current-limiting element in audio amplifiers, as well as other power supplies and automotive systems. Its resistance value is a key factor in determining the amount of current allowed to pass through the resistor at any given time. Due to its through hole construction, the device is able to absorb and distribute the extra heat generated when large amounts of current pass through it. This helps to reduce the danger of overheating and increases the device\'s overall longevity.

The MFR100FTF52-475K is designed to work in a wide range of temperatures, from -55°C to +125°C leading to its robustness in any circuit. It has a maximum power rating of 2W and an operating voltage rating of up to 250V AC and 250V DC. The thermal time constant for the device is 100 seconds, while the maximum frequency of operation is 200 MHz. These characteristics make the device suitable for high voltage, low current applications, such as automotive systems.

The working principle of the MFR100FTF52-475K is based on Ohm\'s Law, which states that voltage is proportional to current multiplied by the resistance. This means that when the voltage increases, the current increases as well, until the resistance limits the flow of current. In the case of the MFR100FTF52-475K, the 475K ohms resistance is responsible for limiting the current, and thus protecting the circuit. The device also serves to reduce electrical noise in the circuit, due to the frequency rating of up to 200 MHz.

In summary, the MFR100FTF52-475K is a type of through hole resistor, used for various applications, from audio amplifiers to automotive systems. It has a resistance value of 475K ohms and is constructed from metal-film elements. Its working principle is based on Ohm\'s Law, which states that voltage is proportional to current multiplied by the resistance, and its thermal time constant is 100 seconds. The device is suitable for high voltage, low current applications as it is able to absorb and distribute heat generated from large currents.
