Inductors are electronic components that store energy in the form of electrical charge. They’re also known as coils, chokes, or reactors. Fixed inductors are passive electronic components that are designed to store electrical energy in a magnetic field when electrical current is passed through them. The ELC-18B682L is an example of a fixed inductor. This article will discuss its application field, working principle, structure, and performance.

Application Field: The ELC-18B682L is primarily used for hardware filtering and power circuit damping applications. It can be used in home appliances, computers, telephones, and other products where filtering or damping is needed. It is also used in low and high voltage switchgear to protect against electrical noise. Additionally, the ELC-18B682L is suitable for filtering out noise caused by inverters or power supplies and is often used as an electromagnetic interference filter and for snubbing circuit applications.

Working Principle: Fixed inductors have a very simple working principle. When electrical current flows through the coils, a magnetic field is created around them. This magnetic field induces electrical current in the coils, which can then be stored in a capacitor. The capacitor then blocks any additional current from flowing through the inductor and prevents damage to the electronic components.
The ELC-18B682L is composed of 18 diameter-sized coils with an approximate diameter of 3 mm. Each coil is wound around a ferrite core, which allows the inductor to cope with larger currents while maintaining a high electrical impedance. The core also helps to efficiently convert the inductor\'s stored energy into electrical energy. This process is similar to how an electric motor works.

Structure: The ELC-18B682L is a radial leaded, surface mounted, molded inductor. It has a housing with a black plastic sleeve. The sleeve has two holes that are used to mount the inductor to a circuit board or other component. The 18 coils are wound around a ceramic ferrite core and are then covered by a plastic shell to protect the core. The core is connected to two terminals on the bottom side of the inductor.

Performance: The ELC-18B682L has a wide range of performance characteristics. Its inductance value ranges from 100 to 1000uH and has a current rating of 8.02A. Its saturable current rating is 4.02A and it can withstand temperatures of up to 105°C. It has a high self-resonance frequency which helps to reduce noise in circuits. Additionally, the inductance value is stable over its temperature range and it also has high Q-value.

In conclusion, the ELC-18B682L is a fixed inductor that is primarily used for power and filter applications. It is composed of 18 coils wound around a ceramic ferrite core, and it has a housing with a plastic sleeve and two mounting holes. Its inductance value ranges from 100 to 1000uH and has a current rating of 8.02A. It also has a high self-resonance frequency and a high Q-value. All these features make it ideal for applications that require a high level of performance.
