A through-hole resistor, or commonly referred to as a TH resistor, is a type of resistor that is designed to be inserted into a printed circuit board (PCB). The resistor is soldered into a hole and connected to the two adjacent traces of the PCB. This allows the resistor to produce a higher amount of resistance to electrical current, which is essential for many electrical circuits and systems. The 42J22RE is a prime example of such a resistor, and in this article, we’ll take a closer look at its application field and working principle.

The 42J22RE is a surface mount (SMT) resistor. It has a power rating of 0.25W and is designed for use in applications where higher current and voltages are needed. Its operating temperature ranges from -40°C to 85°C. The resistance range of the 42J22RE ranges from 0-2.2K Ohms, and the tolerance is ±1%. The resistor features an epoxy coating for durability and is RoHS compliant, ensuring environmental safety.

The basic working principle of the 42J22RE is simple. The resistor works by providing electrical resistance to the passage of electric current. This is achieved by having the resistor absorb the electrical energy that is applied to it. This absorption reduces the intensity of the current flowing between the terminals of the resistor. As a result, the voltage across the resistor is reduced. By reducing the voltage, it reduces the amount of power lost in the circuit.

The 42J22RE is a widely used resistor in many different industries, including automotive, consumer electronics, aerospace, and military. Its high resistance and power rating make it suitable for a wide range of applications, from high current and voltage regulation to low current power supply applications. It is also often used in analog circuitry as it can provide very accurate and consistent resistance values.

The 42J22RE is a reliable and popular choice for power limiting, current limiting, and voltage limiting circuits. It can be used with other components such as capacitors, inductors, and transistors to form more complex devices and systems. It is also used for generating signals, in pulse-width modulation circuits, signal isolation, and many other applications.

The 42J22RE can also be used in filters and other devices to reduce noise and interference. By adding the resistor in series with the signal line, the resistor will absorb some of the energy from the signal, thus reducing the level of noise and interference. This is critical for applications such as audio equipment, where unwanted noise needs to be minimized.

Lastly, the 42J22RE is a popular choice for precision measurement and control. Its accurate and consistent resistance values allow it to be used in conjunction with other components to form precision voltage dividers, current sources, and voltage controlled oscillators. As such, it is an essential component in the design of precision measurement and control devices.

In conclusion, the 42J22RE is a versatile and reliable choice for a wide range of applications. Its high resistance and high power rating make it suitable for power limiting, current limiting, voltage limiting, signal processing, and precision measurement and control. By understanding its application field and working principle, we can make the best use of this resistor and ensure that our projects are always successful.
