Fixed Inductors

Fixed inductors are passive electronic components found in many electrical devices. A fixed inductor is a winding of one or more coils, usually of wire, wound on a ferromagnetic core. The core is typically formed from core material with a high magnetic permeability, such as iron or ferrite.The application field and working principle of AISM-1812-1R5K-T is a perfect example of fixed inductors. AISM-1812-1R5K-T is a ferrite-based fixed inductor specifically designed for high-frequency and power applications, such as for high-frequency switching and power conversion circuits operating at frequencies greater than 20MHz. It can store sufficient magnetic energy in coils to produce high levels of inductance for a given number of turns. This, together with its properties of compact size and high insulation resistance, makes it ideal for use in a wide range of current and voltage regulated controlled circuits.The working principle of a fixed inductor is based on the concept of induced electromotive force (EMF). This occurs when a current-carrying conductor is placed in a changing magnetic field, or when the number of turns on the coil is increased or decreased. When a current flows through the inductor, a stored energy field builds up in the core material, allowing it to provide an impedance to the current. The magnitude of impedance depends on the magnitude of the stored energy and the rate at which it is changing. The stored energy in the magnetic field opposes any change in the current flow, creating a self-induced EMF, or back EMF, opposite to the current.The AISM-1812-1R5K-T has been developed to provide an optimized combination of inductance and current-handling capability. The core material used allows the coil to operate across a wide frequency range and produce high levels of inductance while handling significant currents. This makes it ideal for use in power circuits requiring extremely reliable control of voltage and current.The construction of the core material also provides a high level of insulation between turns, allowing the device to withstand higher voltages without the risk of insulation loss. This prevents the risk of short-circuiting and allows for precise control of the device’s inductance value. It also ensures low levels of capacitive coupling between windings, allowing it to operate as a very high-quality coil in high- frequency switching and power circuits.The AISM-1812-1R5K-T can be used in a variety of different applications. It is suitable for use in power supplies, motor control applications, voltage regulators, high-frequency switching circuits, and for energy storage in distributed capacitance or equivalent circuits. It is also suitable for use in inductive sensing circuits and power factor correction circuits.The AISM-1812-1R5K-T, with its combination of optimized core material and precision winding geometry, provides an excellent choice for a high-quality fixed inductor. Its properties of compact size, high insulation resistance, and wide frequency range make it ideal for use in high-frequency and power applications, offering efficient performance and reliable control of voltage and current.
