Through Hole Resistors, such as the LVR03R0150FE70, exemplify the wide range of electrical components used in many industries. Through hole resistors are resistors that feature two lead wires, or pins, that are placed through a printed circuit board (PCB) and then soldered down. Most often, through hole resistors are used in power supplies, logic systems, and other applications where high power is handled and low resistance is needed.

The LVR03R0150FE70, made by Ohmite, is a high-performance, through-hole resistor. This resistor can handle up to 150V and features a power rating of 3W. It also has a total resistance range of 100 ohms to 3 Mohms. It is designed with an insulated shell and has a lead-free-tinned finish.

The typical application fields for the LVR03R0150FE70 include military/aerospace, industrial and consumer electronics. It can be used as an ideal high power resistor in AC/DC power supplies, circuit protection, motor control, and telecommunications systems, just to mention a few. Similarly, the resistor can be used to attenuate power in antennas, high voltage switching, and other more demanding applications.

The working principle of a through-hole resistor is based on Ohm’s Law, which states that the current passing through a resistor (I) is equal to the voltage (V) across it divided by the resistance (R). Therefore, the LVR03R0150FE70’s resistance (R) is equal to the voltage (V) divided by the current (I), and can be adjusted accordingly. By appropriately choice of values for the resistance and the voltage, the power passing through the resistor can be regulated.

In more complex applications, the use of a through-hole resistor called a surface-mount resistor (SMR) can provide an increased level of performance. The SMR works in the same way as a through-hole resistor, but it is much smaller and requires less space on the PCB. The surface-mount resistor has a higher resistance value because it is made of thin film rather than metal.

Overall, through hole resistors such as the LVR03R0150FE70 provide numerous advantages to electrical engineers and are critical components for many industries. Their compact size, high power capability, and wide range of resistances make them ideal for a variety of applications. Their working principle is based on Ohm’s Law, and they can be used as both through-hole and surface mount resistors. Through hole resistors offer reliable performance and are essential for circuit design and protection.
