Through Hole Resistors

What is SFR2500006981FR500?

SFR2500006981FR500 is a type of through hole resistor, often referred to as a "five watt resistor". It is a device which connected in an electrical circuit, meant to reduce the amount of current flowing in it. It is the smallest suitable part for applications such as power supplies and circuit protection.

Application Field of SFR2500006981FR500

The SFR2500006981FR500 is a high-power resistor which is used in various applications from power supplies to circuit protection. It is used to reduce the amount of voltage passing through a circuit, offering an extra layer of protection for other components in the circuit.This type of resistor can be used in a wide range of industries such as automotive, communication, and energy. Automotive applications include power converters, electric car charging, and airbag system control. The SFR2500006981FR500 can be used in communication systems for Ethernet communication lines, GSM/CDMA base stations, and Wi-Fi. In addition, it is also used in the energy sector, providing power conditioning and voltage regulation for photovoltaic solar cell arrays.

Working Principle of SFR2500006981FR500

A through-hole resistor, such as the SFR2500006981FR500, works by reducing the current that flows through the circuit. It achieves this by introducing a resistance between two points. The resistor consists of an element with an insulation coating and two leads. The insulation coating reduces the risk of an electrical short when current passes through the resistor. The two leads are then connected to two points in the circuit, and the resistance it provides reduces the current. To better envision the working principle of the SFR2500006981FR500, imagine a water pipe being connected to two reservoirs. If the valve on the pipe is opened, then finally a large amount of water will flow through. However, if the valve on the pipe is partially closed, then the water flow will be reduced. This same principle applies with the SFR2500006981FR500—the resistance it provides reduces the current between two points in the circuit.

Conclusion

The SFR2500006981FR500 is a type of through hole resistor which is used in a wide range of industries such as automotive, communication, and energy. It is commonly used as a voltage regulator and for circuit protection, reducing voltage and current between two points in the circuit. It works by introducing a resistance between two points, reducing the current. Through hole resistors, such as the SFR2500006981FR500, offer an extra layer of protection, while providing additional control over the voltage and current in the circuit. This makes it an ideal choice for power conditioning and circuit protection applications.
