ER1537-12KR Fixed Inductors

Fixed inductors are one of the most commonly used components in electronics. The ER1537-12KR fixed inductor is an axial leaded device used in power supplies, low current applications such as radio receivers, and high-frequency RF amplifiers. It is typically used as a smoothing device in varying circuit designs.

Construction

The ER1537-12KR is a high-quality inductor with accurate DC resistance values that guarantee stable voltages and current. It is made with the highest grade of materials available and is precision-wound to ensure reliability. It has a ferrite core with an insulating sleeve and strong magnetic properties, which help keep the inductance of the device stable. Its windings are surrounded by a plastic encasement which protects them from environmental factors and moisture. The outer case also helps protect against physical damage and provides improved insulation against stray electrical fields.

Application Fields

ER1537-12KR fixed inductors have diverse applications in the electronic industry. Its key application areas are in power management applications, such as in power supply circuits, battery chargers, and voltage regulators. It is widely used in AC/DC converters, power factor correction systems, and in the distributed power systems of appliances and motors.The ER1537-12KR fixed inductor can also be used in RF circuitry, such as in signal amplifiers, oscillator circuits, and radio receivers. Additionally, it can be used in filter circuits, in signal transient suppression, and in signal-coupling and decoupling applications.

Working Principles

Fixed inductors work by creating an electromagnetic field when current is passed through them. This can be used to store energy or limit the current going through the device. The inductance of the inductor is determined by the number of turns of wire, the coil area, and the type of core material used.When current flows through the inductor, a magnetic field is generated, which also generates a back-EMF (electromotive force). This back-EMF opposes the current through the component, leading to a decrease in current. In an AC circuit, the back current opposes the current going through the inductor, which results in current flow being limited.The ER1537-12KR fixed inductor is designed for high-frequency applications and provides excellent tolerance and stability for power management applications. By using the ER1537-12KR inductor, engineers can create reliable power systems that ensure efficient performance and stability.
