SCR105B-390

Fixed Inductors provide an efficient method for the electrical induction of AC or DC. These components can be self-contained, or created using coils and transformers. Fixed inductors can come in a variety of forms, including air core, ferrite core, and laminated core.

The SCR105B-390 is an example of a fixed inductor. It is a self-contained component with several additional performance features. It has a maximum inductance of 390 nH, a maximum operating frequency of 20 MHz, and a maximum current rating of 1.45 A. The component also features a low DCR (DC Resistance) of 0.99 mOhm, and 40 mW of heat dissipation power. The SCR105B-390 is constructed with double side metal alloy, copper, and ceramic sacrificial layers.

SCR105B-390 Application Field

Due to its relatively high current ratings and low DCR, the SCR105B-390 makes an excellent choice for inductor applications that require increased efficiency. Common use-cases for this component include:

• Powering low frequency radio receivers and transmitters
• Replacement for transformer-based inductors in high frequency circuits
• Filtering of power in high current circuits

In addition, the SCR105B-390 can be used in various applications where inductor performance is critical, such as medical equipment, aircraft electronics, and communications systems.

SCR105B-390 Working Principle

The general operating principle of a fixed inductor is as follows. In an AC circuit, current is applied to the inductor, inducing an electric field. This electric field opposes the current, causing it to slow down. As a result, the voltage across the inductor decreases, preventing excessive current from entering into the inductor’s output. This is known as inductive reactance, and it creates a phase difference between the applied current and voltage.

The SCR105B-390 is no different in this regard; it follows the same operating principle mentioned above. The only difference is that it has additional performance features, such as low DCR and high current ratings, that make it better-suited for high-performance applications.

Conclusion

The SCR105B-390 is an example of a fixed inductor component. It provides several performance advantages over traditional inductors, including a low DCR and high current ratings. The SCR105B-390 is most commonly used in applications such as powering radio receivers and transmitters, filtering power, and medical equipment. Finally, it follows the same inductive reactance principle of all other fixed inductors.
