MFR1WSFRF52-270R Application Field and Working Principle

Through hole resistors are a type of electronic component that are widely used in the majority of electronic products in the market. This includes microcontrollers, transistors, analog to digital converters and microprocessors. This article will discuss the application field and working principle of the MFR1WSFRF52-270R resistor. The MFR1WSFRF52-270R resistor features a PTC, or positive temperature coefficient of resistance, which enables it to be used as a current limiting device in devices such as power supplies. Unlike traditional resistors, this type of resistor features a low power rating, meaning that it can withstand a maximum current draw of only 0.1 Watts, or about 1.7A. This makes it suitable for use in devices which require low power dissipation such as tiny LCD displays. In addition, the MFR1WSFRF52-270R is designed with a two-part construction. The first part is a fixed core which ensures that the resistance value remains constant. The second part of the construction is the thermally-conductive body which holds the fixed core, and which handles heat dissipation. As the temperature rises, the wattage of the resistor decreases, meaning that the current that can be handled is also decreased. This makes it ideal for use in heat-sensitive circuits.The working principle of the MFR1WSFRF52-270R resistor is relatively straightforward. Its resistance value can be determined by the ratio between its length and width. The higher the ratio, the higher the resistance value. The resistance value is then proportional to the voltage applied across the resistor. As the voltage increases, the current that can be handled decreases. The same principle is also true for the current draw, meaning that as the current draw increases, the wattage of the resistor decreases.In conclusion, the MFR1WSFRF52-270R resistor is a low power, two-part resistor which is designed for use in heat-sensitive circuits. Its resistance value is determined by the ratio between its length and width, and its wattage decreases as the current draw increases. As a result, it is suitable for use in devices which require low power dissipation such as tiny LCD displays.
