Fixed Inductors

Inductors, otherwise known as coils, are electric components designed to store energy in the form of a magnetic field. They are usually assembled from coils of conductive metal, and the 1210-101K fixed inductors are no exception. Used in a variety of applications ranging from industrial control systems to consumer electronics, fixed inductors are essential components in many circuits.

Application Field

The 1210-101K is a fixed-inductor module, meaning it consists of multiple 1210-sized inductors in a single package. This makes it suitable for a wide variety of applications, from DC-DC Power Supplies and motor drives to switching and multiple power conversion stages. This module is particularly suited to automotive systems, given its high temperature stability and resistance to vibration.

In consumer electronics, 1210-series fixed inductors are an ideal choice for use in computers and electronic appliances. They are small enough to fit in many types of circuit boards and electronic design projects, and because they take up less space than other inductors, they are often preferable for these type of systems.

Working Principle

The working principle behind fixed inductors involves the electromagnetic field they create when electricity passes through them. This field is created, in part, by wrapping a conductive coil around a magnetic core, the strength of which is determined by the type of core used. As current passes through the coil, it creates a magnetic field, which in turn stores energy.

Fixed inductors also use a high-frequency switching characteristic to control the current. This is achieved by using a switching frequency higher than the inductance of the coil. When a signal is applied asking for a certain level of current, the fixed inductor uses the switching frequency to determine how much current needs to be provided to satisfy the specific request.

The 1210-101K module consists of two layers of smaller inductors connected in series. Each layer has an independent switching circuit, allowing multiple power supplies to be controlled independently. This arrangement provides a high degree of flexibility in the application of the module, and ensures that the desired level of current is delivered.

Conclusion

The 1210-101K fixed inductor module provides a combination of features that make it particularly useful in automotive systems and other applications where space is at a premium. Thanks to their relatively small size, they can be ideally suited to a variety of electronic design projects, and their working principle makes them efficient and reliable. With the range of applications and the performance they offer, the 1210-101K fixed inductors are a great choice for any circuit board.
