Through Hole Resistors are commonly used to limit or regulate current and voltage passing through an electrical circuit. They are available in a variety of sizes and shapes to match unique application requirements and depend on the type of resistor used. One such commonly-used through hole resistor is the FKN300FR-73-1R3.

Overview of FKN300FR-73-1R3

The FKN300FR-73-1R3 is designed specifically for use in an automotive environment. It is a flameproof resistor, meaning that the resistor is encapsulated in a coat of fire-resistant material to limit the spread of fire, should it become exposed to extreme temperatures or an electrical current overload. The FKN300FR-73-1R3 also features a reinforced insulation layer and a relatively high power rating for greater reliability and safety.

Applications of FKN300FR-73-1R3

The FKN300FR-73-1R3 is widely used in automotive engines, braking systems, and electrical systems. It is designed to control the amount of current travelling through the circuit at a set voltage. It is also used in some non-automotive applications, such as controlling LED lighting and providing power to small electronics. The FKN300FR-73-1R3 is ideal for applications requiring a moderate voltage and relatively high current control.

Working Principle of FKN300FR-73-1R3

The FKN300FR-73-1R3 uses a wire wound construction of an ohmic resistor with a negatively charged anode and a positively charged cathode. This construction creates a resistance in the circuit. When the electric current passes through the resistor, it encounters resistance, which reduces the current and results in a voltage drop across the resistor. This voltage drop is proportional to the resistance of the resistor.

The FKN300FR-73-1R3 has a resistance of 1.3 Ω and a power rating of 300 watts, allowing it to handle high electrical currents while providing reliable protection from overloads. The resistor also has a low DC resistance, meaning that it will not impede the smooth flow of current in a circuit.

Advantages of FKN300FR-73-1R3

The FKN300FR-73-1R3 offers a number of advantages compared to other through hole resistors. It is constructed of materials that provide a high level of flameproof protection, so it is suitable for use in high temperature or hazardous environments. Its high power rating also allows it to handle high current applications without limiting the flow of electricity in the circuit. The FKN300FR-73-1R3\'s low DC resistance also makes it an ideal choice for controlling LED lighting.

Disadvantages of FKN300FR-73-1R3

As with all through hole resistors, the FKN300FR-73-1R3 is not suitable for applications requiring a very low DC resistance. The resin material used for its construction also limits its temperature range to between 40°C and 80°C. Furthermore, because of its high power rating, the FKN300FR-73-1R3 may be more expensive than other through hole resistors.

Conclusion

The FKN300FR-73-1R3 is a versatile through hole resistor, suitable for controlling current and voltage in automotive and other applications. It offers a high degree of flameproof protection and comes in a wide range of sizes and shapes. Though it may be more expensive than other through hole resistors, its high power rating and low DC resistance make it an ideal choice for applications requiring reliable current and voltage control.
