MFR-25FRE52-3M48 through hole resistors (better known as ‘fixed resistors’) are passive components used in many different electronic applications, like circuit protection, voltage regulation, current flow regulation and waveform shaping. Through hole resistors can often be charactersied by its power rating, tolerance, resistance value, dissipation factor, operating temperature range and the amount of voltage it can withstand. MFR-25FRE52-3M48 through hole resistors are generally packaged in a common cylindrical shape. They have two closed ends with a line of metal leads depending from the center, with a wide variety of lead lengths and configurations available. The body of the resistor is typically transparent to providing an ‘easy to see’ digit and letter code for identifying its resistance value. MFR-25FRE52-3M48 through hole resistors come with a 25mW power rating, a 5% tolerance and different resistance values. These resistors also have a low level of noise, a capability to withstand high temperature (up to +150°C) and a very small dissipation factor, allowing them to be used in most demanding applications. The working principle of MFR-25FRE52-3M48 through hole resistors is based upon Ohm\'s Law, which states that electrical resistance is directly proportional to the length and inversely proportional to the area of a given conductor. The three parameters that define an electrical conductor – temperature, voltage, and resistance – are used to calculate the current that flows through the conductor. As current passes through the resistance material, it encounters friction, which results in heat energy, which is dissipated to the air. MFR-25FRE52-3M48 through hole resistors are popularly used in industrial, outdoor, automotive, and telecom applications. Outdoor applications such as street lighting, power distribution, and outdoor signage make use of the enhanced temperature operation and weather resistance of these devices. Its ability to withstand high voltage makes it a great choice for surge protection, where it can be used to help protect sensitive control circuitry from transients or surges in the power system.MFR-25FRE52-3M48 through hole resistors are also popularly used in automotive applications such as in cars, boats and buses. These devices are extremely robust and can handle very high temperatures, making them perfect for automotive applications. They are also used in automotive electrical systems, providing protection for automotive electronics, communications, and other electrical components.In telecommunications applications, these devices are used for signal conditioning, calibration, power limiting, and impedance matching. The ability to withstand high voltage and high currents make them the ideal choice for telecommunications applications. In industrial applications, MFR-25FRE52-3M48 through-hole resistors are used for power limiting, troubleshooting, waveform shaping, and voltage regulation. These devices are often equipped with mounting holes which make them easy to install on the printed circuit boards when involved in high voltage/high current applications.In addition, these resistors are constructed with a heat-resistant building material such as metal oxide that offers excellent thermal conductivity and cleaning properties. Compared to alternate packaging types, these resistors have the benefit of increased power ratings and easier assembly techniques due to their cost savings and smaller sizes compared to conventional resistors. In conclusion, MFR-25FRE52-3M48 through hole resistors are valuable components in a wide range of applications due to their high power ratings, temperature resistance, and excellent thermal conductivity and cleaning ability. When used with the appropriate safety equipment, these resistors can provide reliable, accurate current regulation and protection for a variety of sensitive electrical components.
