Introduction to Through Hole Resistors

Through hole resistors, as the name implies, are resistors mounted and secured through a hole by a screw and nut. The relative simplicity and high breakdown voltage of through hole resistors make them an attractive choice for many applications. Through hole resistors are used to limit the flow of current to protect vulnerable components. They can also act as voltage dividers, allowing voltages within a circuit to drop to specified levels.

FRN300SR47J Resistor Application Field and Working Principle

The FRN300SR47J is a through hole resistor designed to limit current and provide flow control in power converter circuits. This type of resistor offers a high breakdown voltage of 500V, making it suitable for use in high-voltage applications such as microwave ovens, air conditioners, and motor control. It also offers increased temperature resistivity, making it ideal for heat-sensitive applications.In terms of working principle, through hole resistors operate by limiting the current passing through them. When an electric current passes through a resistor, it encounters a certain amount of resistance which reduces the magnitude of the current. This is known as Ohm’s Law, which states that the voltage across a resistor is directly proportional to the current passing through it. Through hole resistors work by providing a variable resistance in the circuit, allowing the current to be limited or controlled.The FRN300SR47J through hole resistor has a power rating of 2W and is suitable for operation up to 250°C. Additionally, it has a tight tolerance of ±5%, and can handle currents up to 3A. It is also RoHS compliant and features a high voltage rating of 500V, making it suitable for use in a wide range of electrical and electronics applications.

Conclusion

Through hole resistors are an essential component of many electrical and electronics circuits, and are used to limit or control the flow of current. The FRN300SR47J is a through hole resistor that can handle currents up to 3A, offers increased temperature resistivity, and features a high breakdown voltage of 500V. This makes it suitable for use in a variety of power converter circuits, microwave ovens, air conditioners, and other high-voltage applications.
