Through Hole Resistors

Through hole resistors are resistors, which are placed on printed circuit boards (PCBs) with the help of plated thru-holes. They are chosen mainly due to their ability to take up a lot of power and their ability to dissipate heat very quickly from the board to the atmosphere. These types of resistors provide very precise voltage and temperature stability.

The RR03J9R1TB is a through-hole resistor with a power rating of 1.3 watts (RR03 series). It has a resistance of 9 Ohms, which means that it will reduce the current flowing through the circuit. It features a ceramic body and has a high temperature range of -55°C to +150°C. The resistor has a high reliability and accuracy with a tolerance of ±2%. The RR03J9R1TB supports lead-free soldering and meets the RoHS and REACH requirements.

The RR03J9R1TB is widely used in applications such as power supplies, electrical systems, robotics, medical electronics, audio systems, and other automotive applications. Due to its ability to withstand temperatures up to 150°C, it can also be used in high temperature environments.

The working principle of a through-hole resistor is straightforward and quite simple. When electricity from a current flow passes through the resistor, it is reduced in strength and regulates the flow of the electricity. This is known as Ohm\'s Law, which states that the current flowing through a resistor is directly proportional to the voltage drop across the resistor.

The RR03J9R1TB is just one example of a through-hole resistor. Although its power rating and resistance are not the highest, it offers reliable performance, and is able to withstand temperatures up to 150°C, making it a good choice for many applications.
