Fixed Inductors

Fixed inductors, also called non-variable inductors, are components with an inductance that is set during manufacture. Inductors are available in a wide range of sizes, shapes, materials, and configurations. The 0603-39NJ is an example of a fixed inductor. It is a 39 Nano-Henry inductor in a 0603 package size. It is available with high-reliability ceramic core construction and a standard shield over the core for added performance.

0603-39NJ Application Field

The 0603-39NJ is used within electronic circuits to provide inductance to reduce or filter noise, power surges, and other interruptions to the electrical current. The inductor is designed for applications such as high-current DC-DC, power supply, and telecom circuit boards. It is commonly used in circuits that require high-current power-control performance, such as mobile phones and network equipment.

0603-39NJ Working Principle

The 0603-39NJ fixed inductor works on the principle of electromagnetic induction. When a current carrying conductor, such as a wire, passes near a magnetic material, such as iron, a magnetic flux is produced. This flux also creates a current around the wire, producing an opposing voltage called an inductance. This inductance is what creates the noise reduction and power surge protection.

The design of the 0603-39NJ utilizes this principle to effectively reduce high frequencies that pass through a circuit. The inductor also absorbs power from the circuit, preventing it from reaching components connected downstream. The 0603-39NJ also features a high reliability ceramic core construction for improved performance. The ceramic core is better at absorbing frequency than a standard wire core, allowing it to better reduce noise in the circuit.

Conclusion

The 0603-39NJ fixed inductor is an effective component designed for high-current DC-DC, power supply, and telecom circuit boards. It utilizes electromagnetic induction to reduce frequencies and protect circuits against power surges. It features a high-reliability ceramic core construction for additional performance and improved noise reduction, making it an ideal component for a variety of applications.
