Fixed Inductors, often simply referred to as inductors, are passive electronic components that store energy in the form of a magnetic field when a current flows through them. This type of inductor is usually used in the form of a coil, and its purpose is to offer a low-impedance path for current flow. The SO603-39NF3S inductor is one particular type of fixed inductor that is widely used in both industrial and consumer applications.

SO603-39NF3S Application Field

The SO603-39NF3S inductor is a high quality, high reliability device with a high saturation current and low DCR. It is ideal for use in circuits involving large current flows, and is suitable for a wide range of applications, including:

• Power management in automotive electronics
• Signal isolation in data communication systems
• LED lighting circuit protection
• Audio and video signal filtering
• DC/DC converters used in server and storage systems

SO603-39NF3S Working Principle

The SO603-39NF3S inductor works on the principle of magnetic induction. When an alternating current (AC) flows through the inductor, it creates a varying magnetic field. This varying magnetic field induces a voltage in the inductor, which is then passed on to the components connected to the inductor. This voltage is proportional to the rate of change of the current flowing through the inductor and is known as the back-voltage or self-induced voltage.

When the voltage running through the inductor is high enough, the current flow through the inductor is limited and this is known as the saturation point. The SO603-39NF3S has a high saturation current, meaning it can handle higher than average levels of current without becoming saturated. This makes it ideal for applications that require high levels of current such as LED lighting and power management in automotive electronics.

In addition to saturation current, the SO603-39NF3S also has a low DCR, which stands for Direct Current Resistance. This is the amount of resistance the inductor has to direct current. A low DCR means that the inductor can offer low impedance paths for current flow - ideal for applications that require low power consumption and good efficiency.

Conclusion

The SO603-39NF3S is an excellent choice for use in applications requiring high current flows and/or low power consumption. Its high saturation current and low DCR makes it ideal for a wide range of applications, including power management in automotive electronics, signal isolation in data communications systems, LED lighting circuit protection, audio and video signal filtering, and DC/DC converters used in server and storage systems.
