Fixed Inductors are electronic loop-shaped components that store energy and gradually releases it after a certain period of time. The most common types of fixed inductors are air-core coils, ferrite-core coils, and shielded coils. They can be found in a variety of applications, from medical equipment and consumer electronics to telecommunications and computer systems.

One type of fixed inductor is the SDS850R-123M. The SDS850R-123M is a high-density, high-inductance, and high-frequency device, designed for high-temperature applications. It features a low impedance which allows it to handle high current. The device also has excellent EMI suppression characteristics, making it ideal for use in mobile phone designs.

The SDS850R-123M is typically used for noise and signal filtering in amplifiers, loudspeakers, computers, POS terminals, and medical equipment. It has a temperature rating from -55C to +105C, making it suitable for use in extreme temperature zones. Its structure consists of two layers of high-permeability elecrolytic powder-magnet, sealed in an epoxy resin, and connected with a multilayer winding to a multipole connector.

The working principle of the SDS850R-123M is simple but effective. As electric current passes through the winding, it creates an electromagnetic field that generates a magnetic flux. The flux links the two layers of powder-magnet, creating a magnetic field, which induces a voltage in the winding.

The induced voltage opposes the current that created it, producing a back-EMF, and consequently reducing the current flowing through the device. This is known as the “back-EMF effect” and it plays an important role in signal filtering. By reducing the current, the device also reduces the amount of noise produced, which results in a cleaner signal.

A few key features of the SDS850R-123M include high temperature capability, high current handling capability, and excellent EMI suppression characteristics. Thanks to its low impedance, it can handle high current, while the sealed internal structure ensures a long life and excellent performance.

Overall, the SDS850R-123M is a reliable fixed inductor and is suitable for a wide range of high-temperature applications. Thanks to its high-temperature rating, low impedance, and excellent EMI suppression characteristics, the SDS850R-123M is a great choice for any device that needs to filter noise and signals.
