Through Hole Resistors

Through hole resistors, or THRs, are components generally used for the protection of circuits, current or voltage regulation, and for biasing active devices. They come in a variety of sizes and shapes and provide an array of resistance and tolerance values to suit almost any application. One of the most popular through hole resistors is the 20J4K7E type.

20J4K7E Application Field and Working Principle

The 20J4K7E type of through hole resistor is ideal for general-purpose application, and is designed to provide good resistance capacity in situations ranging from low to moderate current levels. It is well suited to high-frequency applications, as well as precision measurements. Often, it is used in automotive, aerospace, and military applications where reliability is a priority.

The 20J4K7E resistor is a non-inductive, thin-film element. It functions by producing a predetermined temperature coefficient through its construction materials. Thin-film resistors have a much higher resistivity-per-unit-volume than traditional wirewound (relative to film thickness). This makes them a great choice in applications requiring a certain degree of stability and precision.

The 20J4K7E resistor\'s flat package includes four different insulated shapes (square, rectangle, circular, and round), allowing it to fit a wide range of PCB requirements. Its flat package also minimizes parasitic inductance in high gravitational pulls. Other features of the 20J4K7E resistor include its low noise, low capacitance, and low thermal resistance, making it an ideal choice for low-noise and high-frequency applications.

Moreover, the 20J4K7E resistor has a temperature coefficient of 20 ppm/°C, meaning that it reacts with not much variation when there is mean temperature change present in its working environment. It is capable of withstanding temperatures up to 170°C peak and 130°C maximum temperature. This means that it is suitable for many temperature-sensitive applications. Further, its power rating is 0.7W (at 70°C) and its resistance range is from 0.10 ohms to 3.0M ohms.

Conclusion

The 20J4K7E resistor is a popular through-hole type which has become a go-to option for many circuit protection applications. Its flat package helps to reduce parasitic inductance in noise-sensitive applications. Further, its temperature coefficient (20 ppm/°C) and its ability to withstand temperatures up to 170°C peak make it perfect for many temperature-sensitive applications. Its low noise, low resistance, and low thermal resistance make it suitable for high-frequency applications, too. All these features make the 20J4K7E resistor an ideal choice for a wide variety of uses and applications.
