With the development of electronic technology in recent years, the demand for resistors in electronic equipment has been growing. Resistor products in the market can be divided into two categories: through-hole resistors and surface mount resistors. Among them, through-hole resistors are mainly used in various electronic products, such as mobile phones, notebooks, MP3, computers, and peripherals. In the following, we will introduce the application field and working principle of through-hole resistors, taking MFP25SBRD52-127K as an example. MFP25SBRD52-127K is a 25W through-hole resistor, which is widely used in various electronic products. It has a variety of ratings, including power rating, operating temperature -55℃~+155℃, maximum voltage 2500V. Its power derating compliance index is: inside the temperature range of 0～+70℃, when the power rating is 1/4-15W, the size is 1005 type (2.54×2.54×1.27mm); when the power rating is 16-125W, the size is 1812 type (4.55×3.25×1.58mm); when the power rating is 126-25W, the size is 3528 type (6.50×3.25×1.58mm). The working principle of MFP25SBRD52-127K refers to the principle that the resistance of a resistor is proportion to its resistivity, length and cross-sectional area, while its resistance is inversely proportional to its resistivity. Specifically, when the resistivity is constant, the resistance of the resistor is proportional to its length and inversely proportional to its cross-sectional area. MFP25SBRD52-127K as a common through-hole resistor widely used in various electronic products, its cooling efficiency is relatively strong. In terms of its application, MFP25SBRD52-127K is mainly used in computer, communication and other electronic products. It is mainly used in electronic products with high power requirements, and in electronic products which require long-term operation. Its purpose is to reduce the current flow so as to protect the electronic components from being destroyed due to overload. Moreover, MFP25SBRD52-127K can also be used to adjust the working voltage and current of an electronic product, or it can be used as an R-C element to limit the start-up current or regulate the damping effect. In addition, MFP25SBRD52-127K is also used for shielding or matching the impedance of electronic circuits. In summary, MFP25SBRD52-127K is a type of through-hole resistor, which has a wide range of applications in various electronic circuits. Its working principle is related to the resistivity, length and cross-sectional area of the resistor. In addition, it can be used for current protection, voltage & current adjustment, R-C element setting, and impedance matching.
