Inductors

Welcome to our unique online collection of vintage and hard-to-find electronics components. One of the most popular components we offer is the coil. The importance of a coil in electronics cannot be overemphasized. This passive two-terminal electronic component, also known as an inductor, plays a crucial role in regulating the current in an electrical circuit.

A coil is essentially a conducting wire wrapped in a coil form, which creates a magnetic field when current passes through it. This magnetic field stores energy, which is then released in the form of electric current. Coils are used in a wide range of devices, from simple radios to complex electronic systems.

With us you will find a wide range of vintage coils, perfect for nostalgic restorations, repairs or even educational purposes. Our collection includes both rare and current models, so you will find exactly what you need. Explore the possibilities and find the perfect spool for your project on our website.

Optimize your electronic devices with our high-quality coils. Regardless of your needs, we are ready to help you find the right part. We are your reliable source for vintage and hard-to-find electronics parts.

Introduction
A coil, also known as an inductor, is a passive bipolar electronic component that stores energy in a magnetic field when an electric current passes through it. Coils consist of a wire wound into a spiral coil, and when current flows through the wire, a magnetic field is created. The main characteristic of a coil is its inductance, which determines the amount of stored energy for a given current. Inductance is measured in Henry (H).
Types
There are several types of coils, including air coils, iron core coils, ferrite core coils, and variable coils. Air coils have no magnetic core and their inductance depends on the number of turns of the coil and its shape. Iron core coils and ferrite core coils have a core made of iron or ferrite, which increases the magnetic field and thus the inductance. Variable coils have an adjustable core, which allows the inductance to be changed.
Application
Coils are used in a wide range of applications. They are often used in electronic filters to select frequencies and in radios for tuning to specific frequencies. In addition, coils are used in transformers, where they transfer energy between different circuits. Other applications include inductive sensors, where they are used to detect the presence of a metal, and in electromagnets, where they are used to create a magnetic field.
Product range
There is a wide range of coils available for different applications. They range in size from microscopic coils used in electronics to large coils used in electrical transformers. The values of inductance can also vary from a few nanoHenry (nH) to several Henry (H). In addition to discrete coils, there are also coils integrated into complex electronic components, such as integrated circuits (ICs)
Tech fact
The quality factor or Q factor of a coil is a measure of the quality of the coil. It is the ratio of the coil's reactance to its resistance. A high Q factor means that the coil has low internal resistance and can efficiently store energy. The Q factor is an important parameter for resonant circuits, where it affects the bandwidth and selectivity of the circuit. In practice, the Q factor of a coil is limited by the resistance of the wire, losses in the magnetic core, and radiation and other losses.
