Fixed Inductors

Fixed inductors are electronic components that can store electrical energy when an alternating current flows through them. The ER1840-11KM fixed inductor is a popular choice for a variety of applications due to its long-term reliability, high efficiency, and wide range of application fields.

Application Field

The ER1840-11KM fixed inductor is widely used in many applications such as:

• Radio frequency (RF) circuits,
• Adjustable power filters,
• High-frequency switching power supplies,
• Demodulator circuits,
• Radio receivers,
• FM transmitters,
• Automation controllers.

The ER1840-11KM\'s favorable electrical characteristics and consistent performance make it a great choice for any of the above applications, as well as many others.

Working Principle

The working principle of the ER1840-11KM fixed inductor is based on Faraday\'s Law, which states that when a conductor is placed in a changing magnetic field, a voltage is induced in the conductor. This voltage is then stored by the inductor in the form of a magnetic field.The ER1840-11KM consists of a coil of wire wound around an iron core. The wire is usually connected to two terminals called the primary and the secondary. When an alternating current is applied to the primary terminal, a magnetic field is generated around the coil that is proportional to the current. This magnetic field induces a voltage in the secondary terminal. The amount of voltage induced in the secondary terminal depends on the number of turns in the coil, the size of the iron core, and the strength of the current.The size and number of turns in the coil can be adjusted to give the inductor the desired characteristics for a particular application. In applications such as radio receivers, filters, and transmitters, the ER1840-11KM inductor is often used to regulate the frequency of an alternating current.

Conclusion

The ER1840-11KM fixed inductor is a versatile component that can be used in many applications due to its long-term reliability, high efficiency, and wide range of application fields. Its favorable electrical characteristics and consistent performance make it an excellent choice for various projects, ranging from radio receivers to FM transmitters. The component works based on Faraday\'s Law, and relies on the number of turns, size of the iron core, and strength of the incoming current in order to generate the desired voltage.
