Through hole resistors are passive electrical components used to set and limit electrical current flow in an electrical system. The MFR-50FTE52-143R is a specific type of through hole resistor that can serve a variety of applications. This article will discuss the application field and working principle of the MFR-50FTE52-143R.

The MFR-50FTE52-143R is a fixed-value power metal film resistor with a power rating of 0.5W. This type of resistor has a cylindrical body and consists of two leads on either side, allowing it to be mounted through a circuit board. The device has a knurled end, which facilitates handling during installation, and its leads are coated with a layer of insulation to prevent short circuits. According to the datasheet, the MFR-50FTE52-143R has a tolerance of ±1%, a temperature coefficient of ±120ppm/°C, and a maximum working voltage of 150V.

The MFR-50FTE52-143R is designed primarily for use in circuits where accuracy and stability are of the utmost importance. Its low tolerance makes it an ideal choice for precision electronic circuits, such as those used in timing and sensing applications. Additionally, the resistor is capable of withstanding high surge currents, making it suitable for use in automotive and industrial circuits. As its power rating is relatively low (0.5W), the MFR-50FTE52-143R should generally be avoided in circuits which require higher loads, such as motors or LED arrays.

The working principle of the MFR-50FTE52-143R is similar to other through hole resistors. When voltage is applied to the resistor, some of the current is diverted onto the resistor and dissipated as heat. The amount of current that is diverted, and thus dissipated, is determined by the resistance of the resistor. The MFR-50FTE52-143R is able to maintain a steady resistance value over a wide range of temperatures due to its low temperature coefficient, making it a reliable component in circuits that require accuracy and stability.

In conclusion, the MFR-50FTE52-143R is a through hole resistor well-suited for precision electronic circuits. It has a low tolerance and temperature coefficient, making it ideal for timing and sensing applications. Additionally, its knurled end and insulation-coated leads make it easy to handle and install. Furthermore, its low power rating (0.5W) makes it unsuitable for high-load applications.
