Through Hole Resistors

Through hole resistors are the most common type of resistors used in electronics, and they have existed since the 1950s. They are also known as "through-hole" resistors and are sometimes referred to as "wirewound" resistors. They are typically constructed from a ceramic core surrounded by a metal-film element or an aluminum oxide deposited material. The resistor has two metal parts, the wirewound element, which is made of a metal-film material and aluminum oxide material, and a ceramic core. The ceramic core is often coated with tin, copper, or nickel, which acts as an insulator. The metal-film element, which is made of a copper-coated wire, is wrapped around the ceramic core and soldered to the metal parts.

MFR50SFBF52-400K application field and working principle

The MFR50SFBF52-400K (Metal Film Resistor) is a type of through-hole resistor designed to provide a high resistance to current. This resistor is typically used in applications where high accuracy is needed and noise immunity is also important. It is especially useful in circuit boards that require precise resistance measurements. The MFR50SFBF52-400K has a tolerance of 1% and operates at a temperature range of up to 150°C.

The principle behind the working of the MFR50SFBF52-400K is based on its metal-film element and aluminum oxide material. The metal-film element consists of a copper-coated wire that is wrapped around a ceramic core. When an electric current passes through the metal-film element, it creates an electric field that is counteracted by the aluminum oxide material in the ceramic core. The resulting resistance produced by the metal-film element and aluminum oxide material is what determines the specific resistor value of the MFR50SFBF52-400K.

This type of through-hole resistor is commonly used in a variety of applications, including automotive, medical, and industrial electronics.
