Fixed Inductors: 3094-122GS Application Field and Working Principle

Fixed inductors are components used to store energy in the form of a magnetic field. They are found in almost every electrical system, from tiny electronic devices to large power grids. They are used to regulate the flow of current, acting as unseen “guardians” protecting the system from voltage spikes. The 3094-122GS is a type of fixed inductor which is widely used in commercial, industrial and automotive designs. This article will discuss the application field and working principle of the 3094-122GS.

Application Field of 3094-122GS Fixed Inductors

The 3094-122GS fixed inductor is designed as an integrated package, consisting of a cylindrical core and multiple windings of insulated wire. Typically, the inductor is enclosed in a protective casing to protect the windings and keep them from breaking. The 3094-122GS has a high current-handling capability and low EMI (electromagnetic interference). This makes it well-suited for a variety of applications such as power supplies, switching power supplies, motor controllers, voltage regulators and noise suppression.The 3094-122GS is also known as a “common mode choke”, which is used to reduce the emission and reception of noise from external sources. This type of choke is widely used in high-speed data and power transfer applications, such as in Ethernet cables and USB cables. The powerful EMI suppression capabilities of the 3094-122GS are also beneficial for electronic equipment in environments prone to EMI interference.

Working Principle of 3094-122GS Fixed Inductors

Fixed inductors are passive components, meaning they do not require an external source of power to operate. Instead, they use the current flowing through the windings to create a magnetic field. This field is used to resist changes in the current.When current passes through the windings of a 3094-122GS inductor, a magnetic field is created in the core. This magnetic field is comprised of a number of lines of force, which intersect at right angles to one another and form loops. These loops form a magnetic circuit which stores electrical energy, creating a counter-force that opposes the changes in current.When the circuit is subjected to a sudden change, such as a voltage spike, the counter-force increases and prevents the current from surging. This phenomenon is known as inductor reaction, whereby the magnetic field stores energy and expends it as needed to stabilize the current.Inductors are commonly used in circuits to help reduce noise and interference. The 3094-122GS is designed with multiple windings, which can be configured to reject or amplify certain frequencies. The inductance can be adjusted by changing the number of windings or the diameter of the coil.

Conclusion

The 3094-122GS fixed inductor is an integrated single-chip component, consisting of a cylindrical core and multiple windings of insulated wire. This type of inductor is widely used in commercial, industrial and automotive designs due to its high current-handling capability and low EMI attenuation. The 3094-122GS is also commonly used as a common mode choke to reduce emissions and reception of noise.The working principle of the 3094-122GS is based on the concept of inductor reaction, whereby the magnetic field created within the core stores electrical energy and expends it as needed to stabilize the current. The inductance of the device can be adjusted by changing the number of windings or the diameter of the coil that forms its core.
