Working Principle

The working principle of a through hole resistor is very simple. Whenever current flows through it, the resistor produces a certain amount of heat and dissipates it. The amount of heat produced is proportional to the amount of current flowing through it. The more current flowing through the resistor, the more heat is produced and, as a result, the resistance of the resistor increases. This is known as “self-heating” and can be used to regulate the amount of current flowing through circuits.

By using the RR03J390KTB in a circuit, users can regulate the current to a precise level without having to worry about it getting too hot. This makes it ideal for a wide range of applications, from supplying inputs to controlling the speed of motors.

Conclusion

The RR03J390KTB is an extremely versatile through hole resistor with many different uses. Its wide range of properties and high reliability make it ideal for a variety of applications, such as power supplies, audio equipment, control systems, automotive applications, and inverters. It works by producing a certain amount of heat proportional to the amount of current flowing through it, and this can be used to regulate the current in circuits.
