Through Hole Resistors: MFR-12FTF52-78R7 Application Field and Working Principle

Through hole resistors are power resistors, generally used in medium to high power applications, as well as circuit boards and applications requiring leaded resistors. The MFR-12FTF52-78R7 is an example of such a resistor. This resistor is designed for medium-power applications in the commercial market, with rated power up to 1 Watt. It is commonly used in lighting and automotive industry applications, as well as other applications requiring a leaded resistor. The MFR-12FTF52-78R7 is a leaded power resistor, with two axial leads. The leads are insulated with glass-filled PTFE (polytetrafluoroethylene) sleeves, rated up to 600V, and can be soldered to a variety of substrates, including PCBs and terminal blocks. The body of the resistor is made of repolymerized polyamide, and the metal endcaps are made of treated copper or brass. The resistor elements are precision-wound mini-alloy resistors, which provide excellent thermal, humidity, and shock resistance.The MFR-12FTF52-78R7 operates on the principle of electrical resistance. This principle states that the current flowing through a conductor is proportional to the applied voltage, and the resistance is equal to the voltage divided by the current. As current flows through the resistor, some of it is dissipated as heat, which is why it is important to ensure the resistor can handle the amount of power it is expected to dissipate.The MFR-12FTF52-78R7 has an operating temperature range of -55°C to +150°C, and a maximum dielectric strength of 600V. This resistors is designed to be used in general-purpose applications, and is available in a wide range of resistance values from 1 ohm to 25k ohms. The accuracy of this resistor is 1%, with a temperature coefficient of 50ppm/°C.In addition to being used for general-purpose applications, the MFR-12FTF52-78R7 can also be used for more specific applications, such as precision electronics, power supplies, and surge protection. The resistor can also be used for noise reduction applications, thanks to its low inductance and high surge current rating.Overall, the MFR-12FTF52-78R7 is a good option for a wide variety of medium-power applications, thanks to its precision-wound elements and high surge rating. The leaded design makes it suitable for a variety of circuit boards and substrates, and the operating temperature range makes it suitable for both high-temperature and low-temperature applications.
