Fixed Inductors

Fixed inductors, also known as coils, are electrical components that store energy in the form of a magnetic field. These inductors are widely used in various electrical and electronic circuits and systems, such as power supplies, consumer electronics, communication systems, and radar systems. One of the most commonly used fix inductors is the ER1537-38KM. This specific type of inductor is a low-profile, unshielded, wire-wound, radial-leaded surface mount inductor, with a rated inductance value of 38.0 uH and a saturation current rating of 2.0A.

Application Field

The ER1537-38KM inductor is primarily used in DC-DC converters, DC-AC inverters, and various power supply systems. Its wire-wound construction and low-profile design makes it ideal for applications in high-density circuit boards, such as laptops and tablets, as well as in consumer electronics like TV sets and radios. It can also be used in automotive electronics, particularly in battery management systems, and energy harvesting circuits.

Working Principle

At the most basic level, an inductor is an electrical component that works by creating and storing magnetic fields. When an electrical current is applied to its leads, it generates a magnetic field around the component. This magnetic field stores energy, which can then be used to oppose a change in the flow of current in the device. This opposition to a change in current is known as inductance.The ER1537-38KM inductor works in the same way, by creating and storing energy in its magnetic field. It has a rated inductance of 38.0 uH, and it has a saturation current rating of 2.0A, meaning that it can handle up to 2.0A of current without saturating its magnetic field and losing its inductive properties. This makes it ideal for use in power supplies and other electronics that require high electrical current. The ER1537-38KM inductor also has a low profile design, allowing it to be placed on high-density circuit boards without taking up too much space. This makes it ideal for applications in laptops, tablets, and other compact consumer electronics.

Conclusion

The ER1537-38KM fixed inductor is a low-profile unshielded wire-wound radial-leaded surface mount inductor with a rated inductance of 38.0 uH and a saturation current rating of 2.0A. It is primarily used in DC-DC converters, DC-AC inverters, power supply systems, consumer electronics, automotive electronics, and energy harvesting circuits. This type of inductor works by creating and storing energy in its magnetic field, providing up to 2.0A of current without saturating its magnetic field and losing its inductive properties. With its low profile design, it can be used on high-density circuit boards in laptops, tablets, and other compact consumer electronics applications.
