Fixed inductors are typically made up of a coil of insulated wire wound around an iron core. They are mainly used to store electrical energy in the form of a magnetic field, also known as inductance. Fixed inductors are particularly useful in electronic circuits as they can be used to smooth out voltage spikes and deliver a steady current. They are also used to filter out noise, provide voltage regulation, adjust signal strength, and provide a reference current.

The 2890-20H is a fixed inductor specifically designed to maximize inductance values for low power applications. It has a low winding resistance and is composed of an epoxy-sealed, hermetically sealed aluminum can. The inductance value of the 2890-20H ranges from 0.33 to 0.51µH. Its high resistance to corrosion and temperature further makes it suitable for applications in which exposure to extreme temperatures and humidity is expected.

The working principle of fixed inductors is based on Faraday’s law of electromagnetic induction. Specifically, when a current is passed through the inductor’s windings, a magnetic field is generated around it. This magnetic field stores the electrical energy power and a voltage is induced in the opposite direction. When the current passing through the inductor is interrupted, the stored magnetic field will collapse and an induced voltage will be generated.

The 2890-20H offers a wide range of applications, from use in VCOs and high-accuracy timers to low-noise and high-accuracy amplifiers. It is also well-suited for automotive and motor control modules as it provides effective EMI shielding and inductance value stability over long periods of time. Additionally, the 2890-20H has a high saturation current rating, allowing it to maintain inductance values even under heavy use and high temperature conditions.

The 2890-20H is a reliable fixed inductor that offers high performance and reliable operation in a variety of applications. It is able to provide a steady current without creating noise or voltage spikes and is resistant to temperature and corrosion. Its wide range of applications make it suitable for industrial, automotive, and consumer products that require high-accuracy monitoring and performance.
