Fixed Inductors

Inductors are electrical components that store and release energy in current-carrying circuits. They provide filtering, impedance matching, and tuning functions in a variety of applications. The most popular type of inductors are air-wound or ‘fixed’ inductors, which contain wire wound around a core material commonly made from ferrite, iron, or other non-conductive materials. Fixed inductors are widely used in power supplies, regulators, amplifiers, filters, motor drives, and some telecommunications and medical devices.

1624109-7 Application Field and Working Principle

The 1624109-7 is a surface mount fixed inductor that is used to store energy in current-carrying circuits. It uses an air core winding to create a high value of inductance, along with a ferrite core for additional stability. The device has a maximum dc resistance of 0.7 ohm and features a 10% tolerance. The rated inductance is 18.2 µH along with a rated current of 1.0 A and a self-resonance frequency of 16 kHz. The device can operate in temperatures ranging from -40°C to +85°C, making it suitable for a variety of environments.

The working principle of the 1624109-7 is simpler than that of many other types of fixed inductors. As current begins to flow through the inductor, a magnetic field is created. This magnetic field creates an opposition to the flow of the current, causing the current to decrease. This is known as the inductance. The inductance will continue to increase as the current rises. When the current reaches its peak value, the magnetic field, and therefore the inductance, begins to decay.

The ferrite core increases the inductance by concentrating the magnetic field. The air core winding also increases the inductance as it acts as an additional source of magnetic flux. As the current increases, it will combine with the magnetic field produced by the turning windings of the inductor to form a stronger magnetic field. This produces greater opposition to the current, creating a higher inductance.

The 1624109-7 can be used to provide filtering, impedance matching, and tuning functions in a variety of applications. It is commonly used in power supplies, regulators, amplifiers, motor drives, filters and some telecommunications and medical devices. The device is also used in the design of switched-mode power supplies, where it is used to smooth out the current flow. As well, it can be used in the design of tuned circuits, providing the necessary inductance for the designers to achieve the desired impedance matching.

The 1624109-7 fixed inductor is a convenient and cost-effective component for a variety of applications. With its wide range of temperature operations and its 10% tolerance, it is the perfect component for applications that require reliability and stability. The device’s compact size makes it suitable for applications where space is limited, and with its high inductance rating, it can easily be used for a variety of filtering, impedance matching, and tuning functions.
