Fixed InductorsInductors are passive electronic components that use a magnetic field to store energy. The most common type of inductor is a coil of wire wound around a magnetic core, referred to as a “coil”. When an alternating current passes through the wire, a magnetic field forms around it. This, in turn, creates an opposing magnetic field, which stores the energy created by the current. This stored energy can then be used to power electrical circuits.The 1782-25H is a type of fixed inductor designed for applications requiring repetitive current flows. It is characterized by low winding losses and the ability to withstand high current spikes. This makes it suitable for power electronics applications such as motor controllers and drives, LED drivers, and PFC (power factor correction) circuits, as well as general-purpose electronics such as amplifier circuits. The 1782-25H also offers decent noise immunity and allows for large current transfers with low losses.The 1782-25H is constructed by winding a coil made of copper foil over a ferrite core. The design is known as a ferrite core-wound inductor. The copper foil winding reduces losses, while the ferrite core enhances the inductor’s ability to resist high current spikes. The copper foil also provides improved immunity to external noise interference.The working principle of the 1782-25H is simple. When a current is applied to the inductor, a magnetic field is generated around the coil. This field creates an electromagnetic force that opposes the current, thus limiting the amount of current that can flow through the coil. This effect is known as inductance, and the value of the inductance is determined by the geometry of the coil. The more loops of wire in the coil, the higher the inductance.The 1782-25H is a fixed inductor, meaning it has a fixed inductance value that cannot be changed. The inductance value is determined by the type of core used (in this case, ferrite), the geometry of the coil (in this case, copper foil), and the number of turns in the coil.The 1782-25H is used in many different types of applications, including motor controls, LED drivers, power factor correction circuits, and amplifier circuits. It is well-suited for applications where repetitive current flow is required and noise protection is a top priority.
