Fixed Inductors

Inductors, also known as coils, chokes or reactors, are passive electrical components used in AC circuits to store energy in the form of an electromagnetic field. They are used to oppose the flow of current by providing inductive reactance, allowing energy to be stored in the magnets. Fixed inductors are often used in audio and radio frequency circuits, and one of the most common types is the 103-103FS.

103-103FS Inductors

The 103-103FS is a winding-type inductor with low resistance and a wide range of applications. This type of inductor is mainly used in audio and radio frequency filter circuits, providing inductance and impedance to prevent substantial fluctuation in the current levels. Additionally, the 103-103FS is used as an inductive element in power supply filter circuits as it provides less noise without significantly decreasing current levels.

103-103FS Application Field

The most common application field of the 103-103FS is in filter circuits for amplifier, radio, and television equipment. The inductor can be used to filter out radio frequency interference, allowing for a more consistent signal with less distortion. Additionally, the 103-103FS is commonly used in digital receivers for filtering and limiting signal frequencies. Other application fields of the 103-103FS include antenna conversion systems, instrument amplifiers, radio and television receivers, precision regulators, and switching power supplies.

103-103FS Working Principle

The 103-103FS inductor provides inductance by creating an electromagnetic field when a current is passed through it. The electromagnetic field reacts to electrical current, generating a counter-electromagnetic field that opposes the electrical current through the coil. This opposing force generates resistance or impedance, which reduces the amount of current that is allowed to flow through the inductor. The inductance of the 103-103FS is influenced by both the coil length and the number of windings, allowing for a wide range of inductances to be achieved.

The frequency response of the 103-103FS is determined by the amount of inductance present in the coil. Lower frequencies are allowed to pass through the inductor without much attenuation while higher frequencies are filtered out. This is why the inductor is often used in filter circuits, as it provides a reliable way to filter out higher frequency signals.

Conclusion

The 103-103FS is a winding-type inductor that is primarily used in filter circuits for audio and radio frequency applications. It is capable of providing low resistance and inductance, allowing for precise control of signal frequencies. Additionally, the 103-103FS can be used in power supply filter circuits to reduce noise and ensure a consistent electrical current. Overall, the 103-103FS is a versatile and reliable inductor that is well-suited for use in a variety of applications.
