Fixed inductors are a type of passive electrical components used in a variety of electronic circuits. The 2890-12G is one such product in the range of fixed inductors used in circuit boards and other applications. It is used for EMI (electromagnetic interference) suppression, signal filtering and transient voltage suppression. In this article, we will look at the application field and working principle of the 2890-12G fixed inductor.

Types of Fixed Inductors

Fixed inductors include various types, such as ceramic core, toroidal, iron core, and wire-wound. The 2890-12G is a wire-wound fixed inductor. These inductors consist of a number of windings of insulated copper wire which are wound around a core material such as ceramic, ferrite, or metal powder. The core material provides a magnetic field for the windings, while the copper wire provides a path for current to flow through.

Applications

The 2890-12G is commonly used in a range of applications, including:

• EMI suppression
• Signal noise filtering
• Transient voltage suppression
• Power supply line filtering
• DC-DC converters

The 2890-12G is used to filter out harmonic distortion that can cause power supply noise and interference. This helps to ensure the system runs smoothly and that data is protected. It is also used to reduce the effect of high-frequency transients, known as spikes and surges, which can cause damage to sensitive electronic equipment.

Working Principle

Fixed inductors operate by using an electromagnetic field to induce a voltage in an electric circuit. This voltage is then used to control the amount of current flowing through the circuit. An inductor consists of a number of turns of wire which are wound around a core material. The coil will produce an electromagnetic field when an alternating current passes through it, producing an inductance. This can be used to pass current in one direction while blocking current in the opposite direction. The strength of the inductance can be changed by altering the number of turns in the coil, or by adding additional materials to the core. The 2890-12G has a high inductance rating, which makes it suitable for a variety of applications.

Fixed inductors are used in a variety of applications, due to their ability to filter out harmonic distortion and protect against power supply noise. The 2890-12G is one such product, which has a high inductance rating and is suitable for use in a number of applications. By understanding the application field and working principle of the 2890-12G, designers can use it to create circuits which are protected from harm.
