Through Hole Resistors

A Through Hole Resistor (THR) is a type of resistor with two or more terminals that mount directly through the printed circuit board. It is a passive component used in electric circuits to provide electrical resistance. Through Hole Resistors are also known as “Carbon Film” or “Molded” resistors and are generally used in commercial and industry-specific applications. Generally, these types of resistors are formed by either a film of carbon across two terminals or a small box of powder-like carbon encased in a plastic body.

CW0057R500JE73 application field and working principle

The CW0057R500JE73 Through Hole Resistor is a low cost, general purpose resistor with a value of 500 ohms. It is a metal oxide film resistor in a standard through hole design. The design of the CW0057R500JE73 is compact and economical, perfect for applications where a reliable and stable performance is needed. It is widely used in the circuits of audio, telecommunications, lighting, computer, motor control and other electronic equipment.

The operating principle of the Through Hole Resistor is to reduce the current that passes through the resistor so that it does not exceed a certain level that the resistor is rated at. The resistor works by limiting the amount of current that can flow through it. This is done by the resistors’ resistance, a property of materials which impedes the flow of electrons. As the voltage across the resistor increases, so does the current flow through the resistor. The amount of current that passes through the Through Hole Resistor (THR) depends on the voltage and the resistance value.

The precise resistive value of the THR is determined prior to manufacture, either by an etched, printed-on, or integrated-circuit resistor. The tolerance of the resistance is specified in parts per million (ppm) and can typically range from less than 1% to as low as 0.01%. The temperature coefficient of resistance value is a figure of merit for resistors and defines how accurate the resistance value is over a wide range of temperatures. The temperature coefficient of resistance of the CW0057R500JE73 is characterized as static and can typically range from 25 ppm/K to as low as 5 ppm/K.

In addition to its resistive value, the CW0057R500JE73 also has a power rating as well. The power rating of a resistor indicates the power that the resistor can handle before damages occur due to excessive heat buildup. The CW0057R500JE73 Through Hole Resistor has a power rating of 500mW, more than enough for some basic applications.

The CW0057R500JE73 is a high performance Through Hole Resistor that is perfect for a wide range of applications including audio, telecommunications, lighting, computer, motor control and other electronic equipment. It offers a good compromise between cost and performance with a very low and stable temperature coefficient of resistance and good accuracy over wide temperature ranges. It is an ideal choice for a variety of industrial applications.
