Fixed inductor is an active component whose capacitance remains unchanged with the change of frequency. It is mainly used for generating and storing energy in the power electronic device components. DC1390-274K is a fixed inductor of this kind, a series of single-layer board-type components. Due to its long life, high inductance, low temperature coefficient and strong anti-interference ability, this type of fixed inductor is widely used in power supplies and transformers in various application fields.

The DC1390-274K has a rated inductance of 274kHz, which is suitable for a wide range of applications. The operating temperature range is from -40°C to +150°C, and it can be used in different environmental conditions. It also has a high saturation current of 265mA, up to 3.3A, and a DC resistance of 300mΩ. With its robust design, this fixed inductor can work stably in a wide range of power supply systems for a long period of time.

The working principle of DC1390-274K is based on the magnetic field effect. When operating power passes through the magnetic circuit inside the fixed inductor, it creates a magnetic field, which will induce a voltage on the opposite side of the coil. This voltage creates a current in the opposite direction to the original current, resulting in a closed loop, thus generating an inductor effect. As the magnitude of the current changes, the induced voltage changes as well, creating a linear voltage that is proportional to the rate of change of the current.

Apart from using it as an inductor in power electronically control systems, the DC1390-274K fixed inductor can also be used in switch-mode power supplies, signal filtering and communications applications. As a single-layer board type inductor, it can be easily installed onto printed circuit boards so that it can be quickly and cost-effectively implemented into many high performance applications.

DC1390-274K is a highly versatile fixed inductor that combines enhanced electrical performance with robust design, making it suitable for all kinds of applications in various fields such as power supplies, transformers, switch-mode power supplies, signal filtering and communication applications.
