Fixed Inductors: 3615A100K application field and working principle

3615A100K fixed inductor is a type of electronic component having a composition of two or more coils of insulated wires wound into a core. It is mainly used to set up electromotive force as well as to store electrical energy; it can also be used to filter and protect an electronic circuit. It was developed from the inductance switch in 1970s and became popular in the middle of 1980s in power systems, measuring instruments, radio and other fields due to its features such as low power loss, high power factor, low standby loss, miniaturization, high Q value, high accuracy and durability.

3615A100K fixed inductor is a cylindrical type inductor, belonging to a two-core composed inductor. It is composed of a solid cylindrical core and two cores, one on each side of the core. The cylindrical core is made of ferrite or powder iron which has outstanding advantages in terms of magnetic induction intensity, size, resistance to environmental pressure, temperature stability, and magnetic shielding. The connection between the two cores and the core is established with conductive glue and soldered, guaranteeing stable insulation contact.

In terms of the application field, 3615A100K fixed inductors are mainly used in high power systems, including solar power systems, UPS power systems, DC-DC converters, LED drive power, and hybrid power systems. In addition, they are also used in industrial frequency converters, switching power supplies. Other applications such as the regeneration of low-frequency, high-voltage signals or wireless charging, dithering, noise reduction systems, and dual-energy anti-vibration systems are also possible.

Speaking of the working principle of 3615A100K fixed inductor, it is based on the Faraday’s laws of electromagnetic induction. It stores electrical energy in the form of a magnetic field when current is passed through the coil. This phenomenon is known as inductance. The magnitude of this inductance is proportional to the number of turns in the coil, the core material, and the coil size. When the current stops flowing through the coil, the magnetic field collapses and it releases the stored electrical energy. This process is called back electromotive force, or back emf.

Compared with other semiconductor components, the fixed inductor certainly has its advantages. For example, it has low power loss, high power factor, low standby loss, miniaturization, high Q value, high accuracy and durability. Due to its nature, the fixed inductor offers a great amount of reliability and stability that makes it the choice of modern power systems.

The two options of 3615A100K fixed inductor are molded and SMD type. The enhanced molded is designed to provide excellent EMC performance and features a high saturation current. The SMD type offers stable performance, despite the small size. The different types of 3615A100K fixed inductors are available to cope with different power ambitions.

In conclusion, the 3615A100K fixed inductor is an important component for energy storage. It is used by engineers to design high power DC systems for a variety of applications. It offers the benefits of low power loss, high power factor, miniaturization, high Q value, high accuracy and durability, making it an essential part of modern power systems.
