Through Hole Resistors, or THR, which stands for Through Hole Resistor, are widely used in a variety of industries due to their low cost, utility, and reliability. The THR type of resistors has become ubiquitous among consumer, automotive, and industrial applications. The RWR78S2211FRB12 is a popular THR resistor that has many applications in the market. This article will discuss the application field, working principle, and construction of the RWR78S2211FRB12 through hole resistor.
Application Field
The RWR78S2211FRB12 through hole resistor is used in a wide range of industries, including military, aerospace, automotive, consumer electronics, and industrial control. Its low parasitics, low temperature coefficient of resistance, and reliability make it a preferred component in these applications. The RWR78S2211FRB12 is also ideal for use in transformers, amplifiers, and high-frequency signal conditioning. The high-temperature stability of these components makes it a great choice for applications that require accurate signal control.
Working Principle
The RWR78S2211FRB12 works by limiting current through resistance. This is accomplished through the use of a resistive material, usually carbon or metal oxide. The resistance of the RWR78S2211FRB12 is set upon being tested to a specified value. It is then soldered onto a circuit board, and current flows through it to complete the circuit. The resistance of the RWR78S2211FRB12 limits the current, forming a lower voltage signal that is suitable for the device.
Construction
The RWR78S2211FRB12 is a through hole resistor composed of a resistive element sealed within a cylindrical body made of brass or copper. The resistor is attached to the surface of the board by plating the leads onto the board. This leads to the resistor being placed onto the surface of the board. The other end of the resistor is connected to the appropriate circuit. The body of the resistor is usually coated with a conformal coat that is designed to protect the resistor from corrosion and other damages. This feature makes the RWR78S2211FRB12 a reliable and durable part.
The RWR78S2211FRB12 resistor has become an increasingly popular choice for many applications due to its low cost, reliability, and low-temperature stability. It is a widely used through hole resistor with applications in the military, aerospace, automotive, consumer electronics, and industrial control fields. Its working principle, application field, and construction make it an ideal choice for many applications.
