Resistors are electrical components that have impedance, or resistance, to electric current. They are the most widely used passive electronic components, and are an essential part of almost all electronic circuits. Generally, resistors divide into two categories: Through Hole Resistors and Surface Mount Resistors.The MFR2WSFTF52-21R is a through hole resistor.

MFR2WSFTF52-21R Application Field

The MFR2WSFTF52-21R is a metal film resistor, a type of through-hole resistor. It offers a wide range of resistances, from 0.1 Ω to 25K Ω. This resistor also operates over a wide temperature range from -55 to +155 Celsius. Unlike most metal film resistors, the MFR2WSFTF52-21R features a surge overload rating of 7W, making it an ideal choice for high power applications. It is widely used in automotive electronics, industrial controls, lighting systems, safety circuits, and power supplies.

MFR2WSFTF52-21R Working Principle

The MFR2WSFTF52-21R is a precision resistor with very low temperature coefficient and low noise. It consists of two metal layers, one on top of the other. The bottom layer is a thin film of aluminum or copper, which provides a low resistance path for the current to flow through. The top layer, called a resistor layer, is made up of a combination of materials such as nickel or carbon. This layer helps to distribute the electric current more evenly and efficiently than a single layer of conductive material.

When a voltage is applied to the resistor, the current flows through the metal film and is distributed more or less evenly throughout the resistor layer. The resistance of the resistor is determined by the thickness and composition of the resistor layer. The resistance of the resistor is very stable over time and temperature, making it ideal for use in applications that require precision. The MFR2WSFTF52-21R is also available in a variety of packages, including through-hole and surface-mount.

Conclusion

The MFR2WSFTF52-21R is a through hole resistor, which is widely used in automotive electronics, industrial controls, lighting systems, safety circuits, and power supplies. The MFR2WSFTF52-21R features a surge overload rating of 7W, making it an ideal choice for high power applications. It offers a wide range of resistances, from 0.1 Ω to 25K Ω, and operates over a wide temperature range from -55 to +155 Celsius. Above all, the thin film of aluminum or copper, a resistor layer, and the low temperature coefficient of the resistor make it an ideal choice in precision applications.
