Through Hole Resistors

Through hole resistors, also known as THRs, are one of the earliest passive components used in electronic circuits. They are the cornerstone of electrical engineering and have served as reliable components for decades. THRs are commonly found in a variety of electronic appliances, from the simple LED indicators to the complex printed circuit boards. In this article, we will discuss the 22J3K0 application field and working principle of the THR.

22J3K0 Application Field

THRs feature a variety of sizes and shapes, ranging from the traditional cylindrical shape to square-shaped, which allows designers to customize their layout for any device or application. The cylindrical shape is the most common type of THR because it is the most cost-effective and is the simplest type of resistor to assemble. The 22J3K0 THR is a 0.25-inch cylindrical type and is typically used in electronic devices such as audio systems, computers, and televisions to ensure accurate resistance.

22J3K0 Working Principle

The THR works by having a uniform resistance over its entire length. It is made up of a core material, such as carbon or ceramics, that is surrounded by a conductive material such as copper, iron, or aluminum. This core is then covered with insulation. The resistance of the wire depends on its length, cross-sectional area, and material. When electric current passes through the wire, it will encounter resistance and produce a voltage drop, which causes a decrease in the electrical energy.

The 22J3K0 THR has an operating voltage of 6.3 V and a resistance of 3000 ohms. The operating power is limited to 0.25 watts. The maximum continuous current is 3.2 mA and the maximum surge current is 33 mA. It has an insulation resistance of 5 KOhm and a dielectric strength of 250 VRMS for one minute.

Conclusion

THRs are a reliable and cost-effective component that has been used in a variety of electronic devices for decades. The 22J3K0 THR is a 0.25 inch, cylindrical type that is typically used in audio systems, computers, and televisions. Its uniform resistance over its entire length is determined by its length, cross-sectional area, and material. The THR has an operating voltage of 6.3 V, a resistance of 3000 ohms, and a maximum continuous current of 3.2 mA.
