Fixed Inductors

The fixed inductor is a component made of a single metal coil consisting of a wire round in core, which is used to provide signals or currents in many electronic circuits. The fixed inductor is also known by its trade name of L-07W8N7KV4T. Due to its robustness, the fixed inductor offers relatively large inductance and its range is fine-tuned through a knob for its highest accuracy.

Application fields

The applications of fixed inductors are diverse, making them the preferred choice amongst engineers in various industrial fields. They are commonly used for RF, microwave and signal-line inductance in telecommunication and broadcasting systems, for impedance matching and harmonic filtering in power electronics, and for energy storage in electric power systems. Likewise, fixed inductors are also extensively used in a variety of consumer goods, such as computers, mobile phones, gaming consoles, and audio systems.

Working Principle

The fixed inductor works on the principle of preserving electrical energy in the form of magnetic field and changing electric current into a magnetic field. The coil construction of the inductors provides an inductance value to the signal lines and acts as an energy storage component, which stores the AC sine waves in the form of a magnetic field and then releases it back when necessary. This is done through the help of Faraday’s law of induction, according to which electric current creates a magnetic field around the wire. When the direction of voltage changes, the change in the magnetic field induces an electric current.

Fixed inductors rely on the specific inductance and its Q-factor to decide the coil size and number of turns respectively. The Q-factor specifies the quality of the inductor, with higher values standing for better results in terms of accuracy and power consumption. The specific inductance is the ratio of the magnetic field to the current, and the higher it is, the more the inductance.

Conclusion

Fixed inductors are highly versatile components used in a wide range of applications and are known for their accurate, reliable and stable performance. The fixed inductor L-07W8N7KV4T has a high reliability rating and offers adjustable tuning for easy balancing and fine-tuning. Its wide range of applications makes it suitable for various consumer products, telecommunication devices, power electronics, and electric power systems.
