LR1F3M3

Through Hole Resistors

Through hole resistors are a type of resistor often found in household electric circuits, power supplies and industrial electronic equipment. A through hole resistor is a passive electronic component with a fixed electrical resistance and the ability to limit current. They come in many sizes, shapes and values.

LR1F3M3 is one of the most popular types of through hole resistors. It features precision-made, thick, gold-plated leads and high-resistance ceramic body. The LR1F3M3 is rated for maximum power up to 3 Watts and has a resistance range of 0.8 - 9 Ohms. It has a tolerance of 5%, which means that the resistor can be 5% away from its nominal value. The maximum operating temperature for the LR1F3M3 resistor is 700°C.

Application Field and Working Principle

The LR1F3M3 through hole resistor is designed primarily for use as a current-limiting resistor, however, it can also be used as a voltage-drop resistor. It can also be used to control the output voltage and current on DC circuits. In AC circuits, the resistor helps to provide protection from short-circuiting.

The working principle of the LR1F3M3 through hole resistor is simple. When current flows through the resistor, it creates a resistive force. The resistive force reduces the amount of current that can pass through the resistor, thus limiting the current. The amount of current flowing through the resistor is proportional to the voltage applied, such that if the voltage is doubled, so is the current, and if the voltage is halved, so is the current. The resistor also reduces the voltage across it, which limits the voltage at the load.

The LR1F3M3 through hole resistor is an invaluable component in many electronic circuits and is often used in power supplies, motor control circuits, LEDs, AC circuits and other applications. It is a reliable, cost-effective solution for controlling the current and voltage in a variety of electrical circuits.
