Fixed Inductors: S4924-121K

A fixed inductor is an electrical device purposed to dampen and store kinetic energy in an electromagnetic field. The fixed inductor, also known as a coil, is an essential electronic component as it is mostly used in circuits to create and improve a control signal. The S4924-121K is a fixed inductor and a good example of one of these components. It is a cost-effective single-layer, high-current, axial shielded fixed inductor. This type of inductor is typically used as a replacement component in medical/industrial electronics applications that require reliable performance in low cost. It is also suitable for applications that require high frequency, high current, and low component profile.The S4924-121K is composed of a ceramic dielectric surrounded by a conductive shield and a ferrite core. The dielectric is composed of an alumina ceramic body with a dielectric constant of about 9.44. The ceramic material envelops the core, which is composed of a high-purity ferrite material with low winding resistance and high inductance.The ferrite\'s inductance is created by the magnetic field that is generated when a current is passed through the core. When a current is passed through the core, a magnetic field is set up and this magnetic field is what creates the inductance.The shield is the component of the inductor that protects the dielectric material and core from outside interference. It also helps to prevent interference from other components and also enables the inductor to increase its inductance by producing stronger magnetic fields.The shielding is provided by a plated steel wire which is wrapped around the outside of the dielectric material, creating a shield of magnetic fields. The shielding prevents leakage of magnetic fields that can interfere with other components.The S4924-121K is a low profile component, with a total height of only 4.4mm, making it suitable for miniaturization and space saving. It has a current rating of 1.2A and can be used in a wide range of operating temperatures from -55°C to +125°C.When it comes to applications, the S4924-121K can be used in various electronic devices such as: sampling capacitors, power supplies, filters, oscillators, signal transducers, and signal amplifiers. This inductor is mostly used in high power and high frequency applications. In conclusion, the S4924-121K is an example of the fixed inductor component type. It is a cost-effective and low profile component with a high current rating, suitable for high frequency and high power applications. Furthermore, its shield protects it from external interference and helps to produce stronger magnetic fields, resulting in higher inductance values.
