Through Hole Resistors

Through hole resistors are one of the most common components in electronic circuit designs. They are used in a wide range of applications and are widely accepted as a dependable and cost-effective solution for most high-frequency circuits. This article will examine a particular resistor: MOF4WVJT-77-4R7, exploring its application field and working principle.

Application Field

The MOF4WVJT-77-4R7 through hole resistor is well-suited for a wide variety of electronic applications. It has a maximum operating temperature of 80°C, a tight temperature coefficient of 0.2%/°C, and good power handling capacity. This makes it ideal for use in high-frequency circuits and other applications that require reliable operation across a wide range of temperatures.

The 4R7 resistor is often used in impedance matching circuits due to its low DC resistance and value stability. It is also suitable for shunt and decoupling applications, as well as audio and video signal conditioning, electronic measurement and control systems, and AC and DC motor controllers.

Working Principle

The MOF4WVJT-77-4R7 through hole resistor consists of a ceramic body with a metal layer or film surrounding it. This metal layer is usually copper, silver or nickel-chrome and provides electrical contact with the ceramic body. The resistor then consists of two metallic contact leads extending from both ends of the ceramic body, and a center metal trace connecting the two metal layers. All of these components are routinely found in all types of through hole resistors.

When the voltage across the resistor is increased, current flows through the resistor creating a resistance between the two terminals. The amount of resistance created is determined by the value of the resistor. Values typically range from 0.1 ohms to 100k ohms or more. Resistor values are measured in ohms, and the specific value of the resistor can be computed using Ohm\'s Law: R=V/I, where V is the voltage, I is the current and R is the resistance.

The MOF4WVJT-77-4R7 through hole resistor is designed to handle up to 80°C while exhibiting very little variation in its resistance at lower temperatures. Additionally, the resistor is very stable over time, making it a durable and reliable solution for a variety of electronic applications.

Conclusion

The MOF4WVJT-77-4R7 through hole resistor is an excellent component for electronic circuit designs. Its features make it suitable for a wide range of applications, from impedance matching to shunt and decoupling. Additionally, its tight temperature coefficient and reliable performance make it a dependable and cost-effective solution for most high-frequency circuits.
