Fixed inductors are electronic components that store electrical energy in the form of a magnetic field. They are used in a variety of applications, from radio frequency (RF) and audio circuits, to power supplies and automotive systems. The ELJ-SA180KF is a radial-leaded, multi-layer, surface-mount, non-polarized, fixed inductor. It has outstanding mechanical characteristics, E-MIL and IEC quality standards, and is suitable for a variety of different applications.

General Characteristics

The ELJ-SA180KF has an inductance range of 0.47uH to 3.3uH with a maximum DC current rating of 1.9A and a self-resonant frequency (SRF) of 10MHz. It also has a low DCR (direct current resistance) of 0.03 ohm and a temperature range of -40°C to 125°C.

Material Construction

The ELJ-SA180KF is constructed with an aluminium alloy (electrolytic) coil body and a ferrite core. The device also features an integrated metal and plastic housing which protect it from the external environment and keep its integrity. The construction is designed to improve heat dissipation and mechanical support while providing an efficient magnetic field.

Application Fields and Working Principle

The ELJ-SA180KF is suitable for many different application fields, such as audio and radio frequency circuits, power supplies, and automotive systems. In these applications, the inductors are used to store energy in a magnetic field and to filter out unwanted signals or frequencies. The inductors work by wrapping a conductor around a core material, typically made from ferrite or iron. This wrapped core creates a magnetic field when a current is applied and stores the current as energy in the form of a magnetic field. This stored energy is then used to create or filter out certain frequencies when needed.

The ELJ-SA180KF is a multi-layer inductor, meaning that the windings of the coil are intertwined with each other. This feature increases the inductance rating of the device as well as reduces the overall size. Due to its multiple layers, the ELJ-SA180KF can handle higher current and is suitable for high power applications.

The ELJ-SA180KF is also non-polarized, meaning that the direction of the current does not matter for the device to function properly. This feature allows for greater flexibility and easier assembly, as the inductor can be connected in either polarity, which can be beneficial for some applications.

Conclusion

The ELJ-SA180KF is a high quality, multi-layer, non-polarized fixed inductor suitable for a variety of different applications. Its outstanding mechanical characteristics and quality standards make it a great choice for many projects. The device stores energy in the form of a magnetic field in order to create or filter out certain frequencies, making it a versatile and reliable component.
