MFR100FRE52-309R Through Hole ResistorsThrough hole resistors are widely used in electronic circuits to limit current, divide voltage, change signal levels and improve linearity. The MFR100FRE52-309R is a 1W wirewound through hole resistor with a temperature coefficient of ±350ppm/°C, a tolerance of +-10%, and an average resistance of 52 ohms.This resistor is designed to be used in both commercial and military applications. Its high heat tolerance, low drift, and tolerance makes it ideal for many critical applications. It is also available in several different mounting techniques, allowing it to be tailored to meet the specific needs of any project in which it is used.The MFR100FRE52-309R has its origins in the military. During WW2, the military needed a cost effective way to resist high power transistors in electronic devices such as radios. After the war, the technology was adopted by commercial companies for commercial applications.The MFR100FRE52-309R is built upon a layered sheet of non-inductive high temperature glass cloth material, which is then impregnated with a silicon resin. This provides insulation from electrical interference and also provides increased resistance to mechanical stresses. A wirewound coil is then wound over the cloth, providing both inductive and non-inductive properties. The coil is encapsulated in a ceramic tube which provides additional protection from contaminants such as dust and dirt.When it comes to working principle, the MFR100FRE52-309R is quite straightforward. It functions by creating a resistance to current. This resistance is determined by the physical properties of the resistor such as its size, shape, and material. In the case of the MFR100FRE52-309R, its resistance is determined by the wirewound coil, the glass cloth, and the ceramic tube.The resistance of the MFR100FRE52-309R is dependent upon its size, shape, and material. Its size determines its current capacity, its shape determines the overall length of the resistor, and its material determines the amount of resistance that it will offer. Likewise, the strength of the resistor is determined by the number of turns in the wirewound coil and the type of insulation used.In conclusion, the MFR100FRE52-309R is a versatile, versatile through-hole resistor that provides high heat tolerance and low drift for a range of critical applications. It has a temperature coefficient of ±350ppm/°C, a tolerance of +-10%, and an average resistance of 52 ohms. Its layered sheet of noninductive high temperature glass cloth material, wirewound coil, and ceramic tube provide increased resistance to electrical and mechanical stresses. Understanding how this type of resistor functions and its application field will help ensure it is used correctly and for the right applications.
