Through Hole Resistors

Through Hole Resistors (THRs) are passive components used in electronic circuitry to regulate the amount of current flowing through the circuit. THRs come in various forms, such as Resistor Network, Potentiometers, Rheostat, Zeners, and so forth. However, the H822RFDA is a particular type of THR that is most widely used in the automotive industry.

Features of H822RFDA

The H822RFDA is typically made of a metal or ceramic material with a resistivity rating of around 0,100 ohms. Additionally, the device has a voltage rating of 12V and can withstand up to 28A of current. Besides, the device comes with a tolerance of ± 3%, as well as a thermal resistance coefficient of 0.125°C/W.

Application Field and Working Principle of H822RFDA

The H822RFDA is often used as a power source for automotive applications when regulating current is required. It works by using the resistor in combination with a voltage regulator to restrict the current flowing through the circuit. This helps to manage the power requirements. Furthermore, the resistor also helps to provide safety in the electrical system by protecting it from current spikes that may occur.

Advantages

The H822RFDA THR offers several advantages over other types of resistors. Firstly, due to its low cost, it can be used in large volumes without burning a hole in your pocket. Secondly, its double-sided design provides a higher level of insulation, making it suitable to use in high temperatures. Finally, the device is extremely durable and will last much longer than other THR variants.

Conclusion

The H822RFDA is one of the most common and reliable THR used in the automotive industry due to its low cost and durability. The device is able to regulate the current passing through it, thus providing a safe and maximum performance for the connected electrical system. Therefore, it is highly recommended for those looking to protect their electrical systems from any form of damage.
