Fixed inductors are electrical components used to store and regulate electrical currents. Their primary purpose is to restrict the flow of current so that it does not exceed a certain threshold. The 2890R-12J is a type of fixed inductor that is specifically designed with dual-polarity treatment, enabling it to successfully withstand high current. Furthermore, it has on-chip flux canceling, which helps to reduce the pickup of the traces on the printed circuit board.

The 2890R-12J is widely used in many applications, such as power supply circuits, regulated power supply circuits, voltage regulation circuits, AC/DC switching circuits, DC/DC converters, high frequency converters, motor drivers and other high current power control circuits. It is also suitable for use in harsh environments, due to its robust construction and special coating, which makes it resistant to vibration, shock, and extreme temperatures.

The 2890R-12J is a high-power, high-capacity, low-resistance inductor. It has an inductance of about 0.65mH, and it can handle up to 12A of current. The core material is made of ferrite, and it boasts a very low DC resistance of 0.37 ohms. The working temperature is rated between -25℃ and +85℃.

In terms of its working principle, the 2890R-12J works by storing energy in the form of a magnetic field. When the current travels through the wire, the magnetic field is created, which causes an opposing force to be produced, which in turn reduces the current. This process can be thought of as akin to a ventilator reducing the flow of air, as the fan blades apply pressure to the air flow and reduce its velocity. In this way, the 2890R-12J is able to achieve a high degree of current regulation, which helps to improve the power efficiency of the circuit.

In conclusion, the 2890R-12J is a highly durable fixed inductor that is capable of controlling the flow of current in a number of different applications and environments. Its dual-polarity treatment, low DC resistance, and on-chip flux canceling make it an ideal choice for high current power control circuits. It has an inductance of about 0.65mH, and it can handle up to 12A of current. Its working principle is based on the principle of storing energy in a magnetic field, and this helps to reduce the current, thus improving the power efficiency of the circuit.
