Through Hole Resistors offer a crucial service to electronic circuit design by controlling the current which is allowed to flow around it. This offers protection to those components downstream and assists in helping the circuit function correctly and reliably. An example of these resistors is the LR1F2R4, which is a non-inductively wound type of Through Hole Resistor.

The LR1F2R4 offers a Resistance of 1.2 Ohms, a rated power of 4 Watts and has a tolerance rating of 5%. As with all Through Hole Resistors, the LR1F2R4 is packaged within an epoxy coated UL 94-V0 case, which is moisture proof. This not only secures the resistor and protect it from environmental damage, but its construction also helps dissipate any unwanted heat.

The LR1F2R4 can be used in a variety of applications. It is most suitable for high pulse applications, such as power supplies, switching regulators, as well as motor controls and motor circuits. This resistor is also useful for high-power audio amplifiers, in other audio and RF systems. Additionally, it is suitable for use in consumer electronics, such as toys, home appliances, televisions and audio equipment.

The working principle of Through Hole Resistors is based on the flow of energy. When a current is sent around the resistor, it will create a voltage across its terminals which opposes the current. This is caused by the resistance that the resistor creates and is referred to as Ohm’s Law. This means that the amount of resistance determines how much voltage and current are allowed to flow around it. The LR1F2R4 has a resistance of 1.2 Ohms and can handle up to 4 Watts of power, indicating that it is suitable for a range of uses.

The construction of Through Hole Resistors such as the LR1F2R4 helps dissipate any heat that is created during operation. The cases are usually made from an epoxy-coated UL 94-V0 material, which has good heat resistance. Additionally, the resistor’s body acts as a heat sink, helping to move any heat away from critical components.

The LR1F2R4 Through Hole Resistor is a useful and versatile component for use in a variety of electronic circuit designs. Its resistance of 1.2 Ohms and its ability to safely handle up to 4 Watts of power makes it suitable for numerous applications, from high pulse power supplies to audio amplifiers. Its construction also helps dissipate any heat created during operation, making it a reliable and long-lasting option.
