Fixed inductors, also known as chokes, are electrical components that are used to store energy in an electromagnetic field. They are generally used in electronics, where a brief current flow is converted into a more prolonged supply. The S4924R-475K is a fixed inductor from American manufacturer Vishay Dale that is specifically designed for use in high-reliability power electronic applications.

The S4924R-475K is a high-performance, 75μH inductor with a 0.5 ohm DC resistance. It has a maximum current rating of 6 Amps, with an operating temperature range between -55 – +125°C. The component measures 41.3 x 36.3 x 21.3mm in size and has a maximum power rating of 5 watts.

The primary application of the S4924R-475K is for DC/DC converters, where it is used to filter the incoming current to reduce noise and ripple. It is also used in bridge rectifiers, flyback transformers and motor control data logging systems. The component is suitable for use in higher voltage and frequency switching applications due to its low DC resistance and high maximum current rating.

In its most basic form, a fixed inductor works by generating a magnetic field in response to a current flowing through it. This magnetic field stores electrical energy that is released back into the circuit when the current flow stops. Inductors are polarised components, meaning that they must be connected the correct way round in order to work properly. The S4924R-475K has clear marking on its body to indicate its polarity and an isolation sleeve is used to ensure it is always connected the correct way.

The other component of the S4924R-475K is the core. The core is made from ferrite, and itincreases the inductance of the device by magnifying the magnetic field. This helps increase the device\'s power efficiency, allowing higher levels of current to flow through it without increasing its size.The S4924R-475K also has an epoxy casing which helps protect the internal components from shock and vibration and increases its reliability.

The S4924R-475K is a high-performance fixed inductor that is designed for use in high-reliability power electronics applications. It is an ideal component for DC/DC converters, bridge rectifiers, flyback transformers and motor control data logging systems as its low DC resistance and high maximum current rating make it suitable for use in higher voltage and frequency switching applications. The components durable epoxy casing helps protect the internal components from shock and vibration and its ferrite core helps to increase its power efficiency.
