Through Hole Resistors

Through hole resistors are one of the oldest type of resistors available. They are composed of a cylindrical body with two leads extending through the ends. The resistance of the resistor is determined by the length and diameter of the body and the type of material it is composed of. The leads are then either soldered onto a printed circuit board or clipped onto a tag strip.

RR03J13KTB is an example of through hole resistors. It features a 0.2W rating, a 0.03 ohm resistance and tolerance of 5%. The resistor has an operating voltage of 200V and a TCR value of 200ppm/°C. The conical body measures 8.5mm in length and has a 5mm diameter, and it is made from a unique mixture of carbon and ceramic material.

The body of RR03J13KTB is designed so that it can be installed into a printed circuit board with the aid of a soldering iron. The leads of the resistor are shaped in a cone which aids in positioning and soldering the resistor accurately. The component is also designed to be resistant to heat and mechanical shock, making it very reliable in applications that require a high degree of vibration or shock.

The main application of RR03J13KTB is in powering circuits that require high current flows at low voltages. It can be used to provide voltage regulation in a variety of electrical circuits, including audio systems, analog data acquisition systems, light bulbs, and other appliances. The resistor is also ideal for use in automotive applications, where its high temperature tolerance and high power rating make it an ideal choice for powering automotive electronics.

The working principle of the RR03J13KTB is simple. As current passes through the resistor, a resisting force is created and the amount of the current is determined by the voltage at which the resistor is installed. When exposed to heat, the properties of the resistor body causes it to expand, changing the resistance of the component. The rate at which it expands is determined by the type of material it is made from.
