Introduction

The SFR2500001474FR500 is an example of a special Through Hole Resistor which combines convenience and efficiency of a solderable contacter with the robustness and resolution of modern chip resistors. This particular resistor is designed to suit high pulse current applications and features high power dissipation at low ESR ratings, and a wide temperature range.

Application Field

As mentioned, SFR2500001474FR500 through hole resistors are suitable for high pulse current applications. These include motor drivers, DC-DC converters, back lights, LED drivers, power supplies, and LED lighting. This model in particular has very low ESR values and high power dissipation making it capable of handling high power and current spikes in short duration bursts.

Working Principle

Through hole resistors are constructed with a resistive element formed from a semiconducting or metallic material. These resistive elements define electrical resistance, and the construction of the pattern of the resistors element defines its performance characteristics. Through hole resistor working principles rely on the fact that when a resistor is connected by two or more leads, the resistance created is determined by the number and type of material used in the resistive element.

The SFR2500001474FR500 differs from other through hole resistors in that it has a terminal structure that consists of a copper alloy foil that hugs the resistive element. This allows for improved signal integrity and performance when compared to other through hole resistors. This advanced terminal structure ensures that the connection points remain secure even during high levels of vibration and heavy thermal fluctuations. This improves the resistance characteristics of the resistor and ensures an even flow of current.

Conclusion

The SFR2500001474FR500 through hole resistor is an excellent choice for applications that require high pulse current. It features a robust terminal structure and excellent power dissipation at low ESR ratings, making it a superior choice when compared to other through hole resistors. This model is a great choice for motor drivers, DC-DC converters, back lights, LED drivers, power supplies and LED lighting.
