Through Hole Resistors refer to discrete resistors that are welded to the circuit board or frame by soldering the terminals on both sides. This type of resistors is usually encapsulated in a sealed cylinder of ceramic, plastic, or metal, and the end of the cylinder is provided with a pair of metallic electrode poles, which are welded to the circuit pattern of the printed circuit board through soldering. Through Hole resistors have the advantage of excellent physical strength and good reliability, and the highest power they can achieve is 5-7 watts, which make them very suitable for high-temperature, rugged and hard-core applications.

Among them, ALSR03400R0FE12 is a metal Oxide Film Through Hole Resistor, which features compact size and high durability. Its main applications are in various electronic circuits of LED lighting, signal generator, inductor and transformer, motor control, and industrial electronics. In addition, this product can be widely used in vibration motors, miniature instruments, electronic meters, motion controllers, power supplies of measuring instruments, and various adjustable circuits.

The working principle of ALSR03400R0FE12 is quite simple. It is composed of a resistive film and an end cap. The resistive film is a metal oxide film deposited on a ceramic substrate. It relies on the specific resistor material to establish a specific electric resistance between two ends. When signal current passes through the resistor, the electric current will be dissipated into heat energy in the resistor material, which reduces the voltage of circuit. Generally speaking, larger voltage represents higher power, while smaller voltage represents lower power.

In addition, ALSR03400R0FE12 also features precise power rating and low temperature coefficient. Its thermal design greatly improves its ability to operate in high temperature, compared with other resistors. Its voltage coefficient makes it work reliably in the required voltage, and overall it has excellent heat dissipation characteristics.

In brief, ALSR03400R0FE12 Through Hole Resistor is an ideal solution for electronic circuits, LED lighting, signal generator, inductor and transformer, motor control and industrial electronics thanks to its excellent physical strength and good reliability, compact size and high durability. Moreover, it has excellent heat dissipation characteristics, precise power rating and low temperature coefficient.
