Through Hole Resistors are electrical components that are used to provide a specific amount of resistance in an electrical circuit in order to limit the current flowing through the circuit and protect other sensitive electrical components. The SFR25H0002370FR500 is a Through Hole Resistor that is designed to limit current flow to 500mA and provide up to 70 Ohms of resistance. This specific resistor is designed to be used in high-current environments, such as automotive applications.

Application Field

The SFR25H0002370FR500 Through Hole Resistor is designed for high-current applications, such as automotive equipment. This type of equipment often requires robust components that can handle large amounts of current while still providing accurate resistance levels. This type of resistor is ideal for use in automotive electrical systems, such as ignition systems, lighting systems, or other power circuits. Additionally, this type of resistor is manufactured using a flame-resistant epoxy that provides additional protection from high temperatures and mechanical stresses.

Working Principle

The working principle of the SFR25H0002370FR500 Through Hole Resistor is based on Ohm’s law. According to this law, the current passing through a resistor is inversely proportional to the resistance it provides. Therefore, when the resistor is rated at 500mA, it will provide 70 Ohms of resistance at that amount of current. This resistance value will remain constant until the current passing through the resistor reaches its rated limit. Once the rated current has been exceeded, the resistor will begin to heat up due to the increase in current.

The heat generated from the resistor will cause the epoxy material that it is housed in to expand, thus reducing the area of the resistor and consequently reducing the amount of current that it is able to pass through. This process helps to protect the resistor from further damage due to excessive current. The epoxy material also helps to protect the resistor from mechanical stresses, such as vibration or shock, that may be encountered in an automotive application.

Conclusion

The SFR25H0002370FR500 Through Hole Resistor is designed to be used in high-current automotive applications. The working principle behind this type of resistor is based on Ohm’s law, and the resistor is designed to provide up to 70 Ohms of resistance and limit current to 500mA. Additionally, the resistor is housed in a flame-resistant epoxy in order to provide additional protection from extreme temperatures and mechanical stresses.
