Fixed Inductors

An inductor, also known as a coil, choke, or reactor, is a two-terminal electronic component that stores electrical energy in a magnetic field when electric current flows through it. It consists of a wire loop or coil that is usually wound around a core or very small form factor air-core coil. Fixed Inductors are exactly what their name implies, inductors that have a set or fixed number of turns in the wire loop and is commonly used in telecommunications, high frequency switching power supplies, and in RF applications such as RF receivers and transmitter. The 9405-12 is a type of fixed inductor that is commonly used in these applications.

9405-12 Application Field and Working Principle

The 9405-12 fixed inductor is a chip-type inductor that is designed for use in high current power circuits. It is typically used as an input and output filter in portable communications equipments, such as cellular and cordless telephones, two-way radios, and other equipment that require small line components. It is also used in applications where space is a factor, such as vehicular and automotive electronic systems.

The 9405-12 fixed inductor has a wide range of applications due to its layout and high current rating, wide temperature range, and stability over a wide frequency range. It is often used in circuit board designs where the component footprint size is kept to a minimum. This inductor is also designed to resist both static and dynamic shock to ensure long-term reliability and performance.

The 9405-12 fixed inductor works on a simple principle, that of Faraday’s law of induction. When a conductor is placed in a magnetic field, an EMF, or electrical potential energy, is created. This potential energy is equal to the rate of change of the flux linkage, measured at the conductor section, multiplied by the number of turns of the conductive coil. In the 9405-12 inductor, the potential energy created in this manner is used to filter signals and reduce noise, creating a more stable power output.

The 9405-12 fixed inductors have a self-resonant frequency that is typically higher than 10 MHz. It also has a high inductance to current ratio, with inductance values ranging from 0.01 to 10 μH. It has a relatively high winding resistance and is not suitable for DC power applications. The inductors can be mounted on FR 4 substrates with a solder-reflow or bond-attach technique.

In conclusion, the 9405-12 fixed inductors are suitable for use in a wide variety of applications due to their small component footprint, robust construction, and wide operating temperature range. The inductors offer excellent noise reduction and low power consumption, making them ideal for high frequency switching power supplies, RF and telecommunications applications. As the world of technology advances, the 9405-12 fixed inductors will continue to increase their presence in circuit designs.
