Fixed Inductors

IMS05SH331K Application Field and Working Principle

Fixed inductors are used for a variety of applications, such as line filtering, voltage regulation, and energy storage. The IMS05SH331K is a fixed inductor from Johanson Technology, Inc. that is designed for a wide range of applications, such as radio frequency (RF) filters, line inductors, and high-temperature switching power supplies. It is available in a package size of 5mm x 5mm, with a maximum height of 1.6mm.

The IMS05SH331K fixed inductor is made with high-temperature Mn-Zn ferrite cores, features an operating temperature range of -25°C to +105°C, and has a shielding layer to prevent stiction, a form of adhesion resulting from the static and dynamic forces between objects. This layer prevents the inductor coil from sticking to other components and reduces mechanical shock. As a result, the IMS05SH331K has exceptional stability, even under harsh conditions.

Fixed Inductor Working Principle

A fixed inductor is an electrical component that stores energy in the form of a magnetic field. It consists of a coil of wire wound around a core, which can be made of iron, ferrite or powdered iron. When an alternating current flows through the coil, a magnetic field is created around the core material. The amount of flux produced depends on the inductor\'s size and construction. The amount of current that passes through the inductor is limited by the reactance of the inductor, as set by the inductance.

The two actuators of a fixed inductor are its inductance and current. Inductance is the ratio between the magnitude of the inductor\'s magnetic field and the amount of current that passes through it. It is typically measured in henries, which is the amount of inductance required to generate one ampere of current when one is applied across one ohm of resistance.

The current is limited by the amount of flux produced by the inductor. This is known as the inductor\'s inductive reactance, also measured in ohms. When an alternating current is passed through a fixed inductor, the reactance of the inductor affects the amount of current that can flow through it. When the reactance is higher than the resistance, the current is decreased, creating a minimum current value. When the reactance is lower than the resistance, an infinite current can pass through the inductor. This is known as resonance.

The IMS05SH331K Inductor produces a very low inductive reactance, allowing a wide range of current to be passed through it. This makes it an ideal choice for RF filters, line inductors, and high-temperature switching power supplies, as well as other applications that require high efficiency and low power requirements.

ConclusionThe IMS05SH331K is a high-efficiency fixed inductor with low inductive reactance and exceptional stability. It has many uses in applications ranging from radio frequency filters to high-temperature switching power supplies. The use of high-temperature Mn-Zn ferrite cores and a shielding layer to prevent sticking further contribute to its success. Its working principle relies on the reactance of the inductor, which is determined by its inductance. This feature makes the IMS05SH331K an ideal choice for many applications.
